Burnt Sugar Caramel Cake

This unique and absolutely divine burnt sugar caramel cake gets its flavor from burnt sugar syrup. Cook sugar until caramelized, then add boiling water. We’ll use the syrup in both the cake and frosting. Add salted caramel for extra flavor and toasted pecans for a lovely garnish. It’s soft, buttery, and totally worth every minute of prep time.

It’s been a year in the making. I’m proud to finally share my version of caramel cake, a new cake recipe inspired by a favorite that my mother-in-law enjoyed when she was younger.

What is Burnt Sugar Caramel Cake?

This burnt sugar caramel cake is a wonderfully sweet and buttery cake flavored with homemade burnt sugar syrup. The syrup combines caramelized sugar and water, a mixture you cook on the stove until it’s dark amber in color. The cake does not taste burnt, bitter, or charred. Rather, it tastes like caramel and caramelized sugar, the same topping used for creme brûlée! We’ll flavor the frosting with burnt sugar syrup as well. Inside the cake and frosting, the syrup tastes like caramel. In my experience, this is the only from-scratch caramel flavored addition that (1) provides flavor and (2) doesn’t ruin the cake’s texture.

Behind the Recipe

This is not the exact recipe that my mother-in-law used to enjoy. Sadly, she was unable to find her original. She tried a few online recipes for burnt sugar cake, but none of them lived up to her memories. I researched a few recipes and after testing them myself, I was pretty disappointed at the dense texture and lack of flavor. I tried adding brown sugar and more vanilla for extra flavor, but nothing proved successful. So I turned to my white cake recipe, a cake that’s consistently soft and flavorful. My white cake is the starting point for strawberry cake, pistachio cake, and coconut cake because it’s ALWAYS a winner.

My MIL said it’s the only burnt sugar cake most resembling what she enjoyed growing up!


How to Make Burnt Sugar Caramel Cake

  1. Make Burnt Sugar Syrup: After cooking it, cool the syrup before using in the recipe. Use half in the cake batter and half in the burnt sugar frosting.
  2. Prepare Cake Batter: Since we’re adding a liquid (the sugar syrup), reduce the sugar and milk in my white cake recipe. We’ll also leave out 1 egg white to really ensure that this cake isn’t too wet. Cake flour promises a soft crumb, egg whites (no yolks) promise a fluffy crumb, and sour cream promises a moist crumb. For best results, do not make any ingredient substitutions.
  3. Bake the Cakes: As a result of the burnt sugar syrup cooking, the cakes develop a golden crust around the edges. For a 3 layer or 9×13 inch cake, see recipe notes.
  4. Prepare Salted Caramel: To boost the caramel flavor in this cake, I highly recommend filling and garnishing the cake with my 4 ingredient salted caramel. You can even prepare the salted caramel a few days ahead of time.
  5. Make the Frosting: The burnt sugar frosting is just like my vanilla buttercream, but we’ll add burnt sugar syrup for flavor. To complement the flavor, use extra salt. If you love salty sweet, this is the frosting for you!
  6. Assemble & Frost the Cake: 2 layer cakes are pretty easy to decorate. For a little garnish, I love topping the cake with toasted pecans. See recipe note for instruction.

Video Tutorial: Burnt Sugar Caramel Cake


Prepare the Burnt Sugar Syrup First

The most important step in this cake recipe is preparing the burnt sugar syrup. You need a sturdy 3 quart pan to ensure the cooking sugar doesn’t crystalize. (This pan is great quality for its price.) Cook 1 cup granulated sugar over medium heat, stirring constantly with a wooden spoon. Wooden spoons do not conduct heat and are ideal for candy-making. After chipping a few of my old wooden spoons, I just bought this set and LOVE them!

After about 5 minutes, the sugar begins to melt. If you notice any clumps, try to break them up with your spoon. So far in the process, this is the same exact way we start salted caramel. Once there are no lumps and the sugar is golden brown, about 8-10 minutes total, very slowly drizzle in 3/4 cup of boiling water. Have boiling water at the ready for this step because in the world of candy-making, timing and temperature are key. Wear an oven mitt because the water will rapidly sizzle and steam.

You don’t need a candy thermometer for this, but you can use it if you have one.

After you add all of the water, cook the syrup for an extra 3 minutes over low heat then cool the syrup completely. It will thicken as it cools. Once cool, you can use it in the cake batter and frosting. The cake batter is light beige and smells incredible. Steal a taste!

Buttercream

Same goes for the burnt sugar frosting– make sure you steal a few tastes! You need:

  1. Unsalted Butter: Make sure you’re using room temperature butter.
  2. Confectioners’ Sugar
  3. Burnt Sugar Syrup
  4. Milk
  5. Vanilla Extract
  6. Salt

I love this salty sweet frosting. It’s similar to my salted caramel frosting, but has a much creamier consistency. The burnt sugar cake and burnt sugar frosting are definitely worthwhile on their own, but this entire cake is greater than the sum of its parts. Together, they’re the perfect match.

Don’t Forget the Salted Caramel!

This burnt sugar caramel cake wouldn’t be as impressive without salted caramel. Drizzle salted caramel in between the cakes and on top. If the salted caramel is too warm, however, it will melt the frosting. See my recipe instructions below.

Toasted nuts add a flavorful and textural flair!

Description

The trick to burnt sugar cake is to use burnt sugar syrup as its main flavor. Make sure you prepare the burnt sugar syrup ahead of time so that it can properly cool and thicken. While you’re at it, prepare the salted caramel ahead of time too.


Ingredients

Burnt Sugar Syrup

  • 1 cup (200g) granulated sugar
  • 3/4 cup (180ml) boiling water

Cake

  • 2 and 1/2 cups (250g) sifted cake flour* (spoon & leveled)
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1 teaspoon salt
  • 3/4 cup (1.5 sticks; 170g) unsalted butter, softened to room temperature
  • 1 cup (200g) granulated sugar
  • 1/2 cup (120ml) cooled burnt sugar syrup
  • 4 egg whites, at room temperature
  • 1/2 cup (120g) sour cream, at room temperature
  • 2 teaspoons pure vanilla extract
  • 1/2 cup (120ml) whole milk, at room temperature

Burnt Sugar Frosting

  • 1 cup (2 sticks; 230g) unsalted butter, softened to room temperature
  • 4 cups (480g) confectioners’ sugar
  • 1/2 cup (120ml) cooled burnt sugar syrup
  • 1 teaspoon pure vanilla extract
  • 2 Tablespoons (30ml) whole milk or heavy cream
  • 1/4 teaspoon salt

For Assembly


Instructions

  1. For best success, read the recipe in full and watch the video tutorial in the post above before starting.
  2. Prepare the burnt sugar syrup first so it has time to cool. Make sure you have boiling water at the ready. For the burnt sugar syrup, place sugar in a medium saucepan over medium heat. Best to use a 3 quart heavy-bottomed quality saucepan. Stirring constantly with a wooden spoon, cook until the sugar has completely melted and is amber brown, about 8-10 minutes. If the sugar is clumpy, break up the lumps with your wooden spoon. A candy thermometer is not necessary, but if you’re using one, the sugar temperature should reach about 300°F (149°C) when it’s ready. Turn the heat to low and very carefully and slowly drizzle in the boiling water, a little at a time. Stir after each addition and stand back, as the mixture will rapidly sizzle and bubble. After all of the boiling water is stirred in, stir and cook the sugar syrup for 3 more minutes on low. Turn off the heat and let it cool completely, overnight preferred. It’s imperative that the sugar syrup is completely cool. You will have about 1 cup of syrup.
  3. Preheat oven to 350°F (177°C). Grease two 9-inch cake pans, line with parchment paper, then grease the parchment paper. Parchment paper helps the cakes seamlessly release from the pans.
  4. Whisk the cake flour, baking powder, baking soda, and salt together. Set aside.
  5. Using a handheld or stand mixer fitted with a whisk attachment, beat the butter and sugar together on high speed until creamed, about 2 minutes. Scrape down the sides and up the bottom of the bowl with a rubber spatula as needed. With the mixer running on medium speed, pour in 1/2 cup of the cooled burnt sugar syrup. Beat until combined. Scrape down the sides and up the bottom of the bowl as needed. Beat in the egg whites, sour cream, and vanilla extract. With the mixer on low speed, add the dry ingredients just until combined. With the mixer still running on low, slowly pour in the milk until combined. Do not over-mix. The batter will be slightly thick.
  6. Pour batter evenly into prepared cake pans. Bake for 23-25 minutes or until the cakes are baked through. As a result of the burnt sugar syrup cooking inside the cake batter, the cakes brown nicely on top and on the sides. To test for doneness, insert a toothpick into the center of the cake. If it comes out clean, it is done. Allow cakes to cool completely in the pans set on a wire rack.
  7. As the cakes cool, I suggest making the salted caramel. The salted caramel adds necessary flavor. We’ll use it as a filling and garnish. When ready to use in step 9, make sure the salted caramel isn’t too hot anymore. If it’s too hot, it will melt the frosting. If it’s too cool, it won’t drizzle. Let it cool for at least 30 minutes before using. If you prepared the salted caramel ahead of time and it became too cool or too thick, microwave it for 5-10 seconds or JUST until it’s drizzle-able again. (It won’t be too hot at this point.) You can also toast the pecans during this time, too. See recipe note.
  8. Make the frosting: In a large bowl using a hand-held mixer or stand mixer fitted with a paddle attachment, beat the butter on medium speed until creamy, about 1-2 minutes. Add confectioners’ sugar, remaining 1/2 cup of cooled burnt sugar syrup, vanilla extract, milk/cream, and salt. Beat on low speed for 30 seconds, then increase to high speed and beat until completely combined, about 2 minutes. Add more confectioners’ sugar if frosting is too thin or more milk/cream if frosting is too thick. Taste. Add more salt if desired. (I usually use 1/2 teaspoon of salt total. I like this frosting salty/sweet.)
  9. Assemble and frost: First, using a large serrated knife or cake leveler, slice a thin layer off the tops of the cakes to create a flat surface. Discard (or crumble over ice cream!). If you have any leftover burnt sugar syrup, drizzle over leveled cakes. I usually don’t have any leftover, but this is a great place to use any last drops if you have some. Place 1 cake layer on your cake stand or serving plate. Using a large icing spatula, evenly cover the top with frosting. Drizzle 1/4 cup of salted caramel on top of the frosting. Top with 2nd cake layer. Refrigerate the cake for at least 30-45 minutes before finishing the frosting and garnish. The caramel inside the cake must “set.” After chilling in the refrigerator, spread the remaining frosting all over the top and sides. Run a bench scraper around the cake to smooth out the sides, if desired. Garnish with toasted pecans and more salted caramel. Slice and serve.
  10. Cover leftover cake tightly and store in the refrigerator for up to 5 days.

Notes

  1. Make Ahead & Freezing Instructions: Prepare burnt sugar syrup up to 3 days ahead of time. Cover and store at room temperature until ready to use. Prepare the salted caramel up to 1 week ahead of time. Cover and store in the refrigerator until ready to use. You can prepare the cake layers ahead of time too. Wrap the individual baked and cooled cake layers tightly and refrigerate for up to 2 days or freeze up to 3 months. (See How to Freeze Cake for instructions.) Bring cake layers to room temperature, then continue with step 7. Frosted cake freezes well, up to 3 months. Thaw overnight in the refrigerator, then bring to room temperature before garnishing with caramel and pecans and serving.
  2. Special Tools: KitchenAid Stand Mixer, Wooden Spoons, Stainless Steel Saucepan, 9-inch Cake Pans, Straight Frosting Spatula, Bench Scraper, and Wood & Marble Cake Stand
  3. 3 Layer Cake or 9×13 Inch Cake: You can also prepare this cake as a 3 layer cake or 9×13 inch sheet cake, but the texture tastes best at the thickness of a 2 layer cake. I highly recommend sticking to a 2 layer cake. For a 3 layer cake, though, divide batter between three 8-inch or 9-inch cake pans and bake for 20-22 minutes or until a toothpick inserted in the center comes out clean. For a 9×13 inch cake, pour the batter into a greased and lightly floured 9×13 inch pan and bake for 40 minutes or until a toothpick inserted in the center comes out clean. Top with a thick layer of frosting and drizzle salted caramel all over the top.
  4. Cupcakes: Recipe yields 30-36 cupcakes. Fill cupcake liners 2/3 full with batter. Bake for 20-22 minutes or until a toothpick inserted in the center comes out clean.
  5. Cake Flour: If you can’t get your hands on cake flour, use this cake flour substitute. I suggest doing this 3x, then remove 1/2 cup since you need 2 and 1/2 cups in this recipe.
  6. Egg Whites: Egg whites (no yolks) are KEY to the cake’s fluffy texture. Here are recipes using leftover egg yolks.
  7. Why Room Temperature? All refrigerated items should be at room temperature so the batter mixes together easily and evenly. Read here for more information. Instead of sour cream, you can use plain yogurt. The cake won’t taste as rich, but it’s a fine substitute.
  8. Salted Caramel: No matter which size cake you make, or if you make cupcakes, you’ll have salted caramel leftover. Here are 50 ways to use salted caramel if you need inspiration for the leftovers. I don’t recommend halving the salted caramel recipe– make the whole recipe (1 cup).
  9. Toasted Pecans: Toasting the pecans is optional, but adds incredible flavor to the garnish. To toast, preheat the oven to 300°F (149°C). Spread chopped pecans onto a parchment paper or silicone baking mat lined baking sheet. Toast until slightly darkened, about 5-7 minutes. Cool before using as garnish.

  1. Oh. My. Goodness. There are really no suitable words to describe this cake that will do it justice. It looks AMAZING!!! The description reminds me of burnt caramel ice cream 🙂 I am DEFINITELY going to try this one out! I was searching for the perfect recipe to make for our first connect group of the fall, and this as cupcakes wins hands down! I can’t wait to try it! 😀

  2. Wow wow wow Sally!!! This cake looks amazing! I had never heard of burnt sugar caramel cake before but I am so trying this……one of the reasons I love your blog because you provide us with all the classics and then different recipes that aren’t so common but are equally as delicious – thank you Sally!

    1. I believe this cake could easily be made nondairy. Replace the butter with a butter substitute like Earth Balance (get the sticks, not the tub) and replace the sour cream with a nondairy yogurt- there are several different kinds made with soy, coconut, or almond milk. Replace the milk with any nondairy milk. The only tricky part would be the caramel sauce- if you google “nondairy caramel sauce recipes” you will fine some. BTW these substitutions make the cake nondairy, but not vegan (because of the egg whites.) if you need it to be vegan you would be best off finding a recipe for vegan white cake and figuring out how to incorporate the burnt sugar syrup. It might take some creativity but I think it could be done!

  3. If one was to make it a 9×13 cake, would you just drizzle the caramel on top of the frosting? Would you make half a recipe of it? Thank you.

  4. That looks amazing! Does the frosting pipe well? I might make this into cupcakes for my next gathering. Can’t wait to try it!

  5. This looks amazing! I made a burnt sugar cake before but the cake was similar to a pound cake. Yours looks much more to my liking!

      1. Hi Maria! As in some sugar that did not melt? As the caramel cooks, you can try to break up any large lumps with your spoon.

  6. YAY!!! I’m making cupcakes for my sister in law’s baby shower next month, and needless to say I need to bake a llllot of them. She requested salted caramel as a flavor component so I think I will use this recipe =) She and my brother were married the same day that you welcomed sweet Noelle into the world, and they are expecting their first baby girl right around the holidays! Thanks for saving the day (as always.)

  7. This looks absolutely amazing! I cannot wait to try it and that day may have to be tomorrow! I made your cheese bread and pumpkin pie yesterday so I may need to wait until tomorrow as there’s leftover pie but I want to make it today so bad! We shall see! Thank you for all your wonderful recipes! We are so lucky!

    1. It sounds like you had a delicious weekend, Melissa! Thank you for baking so many of my recipes- I hope you get a chance to make this cake! 🙂

  8. I am so glad you have finally got a caramel cake recipe on here. I have several recipes from my great grandmother and even further back and of course, I have tried to make them but with those people no longer being around, it is hard to get it just right. And now we have you to show us how to get it just right. Thank you so much! I look forward to trying this one as soon as I get the time!

  9. Also, I was thinking that if you made cupcakes and wanted to use up all the caramel, you could fill the cupcakes with caramel as well as drizzling it on top! Do you think that would work out, Sally? Or would there not be enough caramel to fill all thirty cupcakes?

  10. Hi Sally! Maybe this is a silly question, but how much of that “burnt” flavor gets into the cake? I love salted caramel but the second it gets too dark and bitter I’m not a fan. If there is any burned/bitter flavor, I could just reduce the cook time on the syrup, right? Thanks!

  11. Hi Sally, this sound Delicious! Thinking of making it for my daughter’s birthday party with her friends(we had your chocolate cake with chocolate truffles for her birthday with family in August, next week is her party with her school friends).
    I need to know if this frosting can hold the weight of fondant covering the cake,please? Thank you! X

      1. Thanks Sally, I tried pausing the ad blocker but that didn’t work. I’ll try the facebook link. Don’t want to miss anything!

  12. I made this cake this week and wow was it good!! Thank you sally!! I wish I could send you a picture of the cake

      1. Hi Sally,

        Mine looked just like yours and tastes great. Actually it looks just like your Icing in your picture of it in the bowl. But in the picture of your finished cake the Icing looks white that is what is throwing me off.

  13. OK, this is the best cake on the planet. No questions about it. I made this for our connect group and everybody raved about them! They are so so so so so good, Sally! The batter is absolute heaven by itself, and the cupcakes were the fluffiest, softest ones I have ever tasted. Honestly, they were SO fluffy! I filled the cupcakes with a little concoction of sugarless whipped cream with lots of caramel folded into it, and it was great. These cupcakes are probably some of the best I have ever made! I did find that the frosting waa extremely sweet though. I suppose that can’t be helped, what with all the powdered sugar and the burnt sugar syrup. Do you think there’s an alternative frosting/topping that wouldn’t be so crazily sweet? Thanks!! 😀

  14. Made this for an extended family dinner. It was a huge success, even with my super picky husband who thinks caramel cake is too sweet! The salted caramel drizzle was the key. Thank you!

    1. I’m so happy this cake was a hit with your family, Lisa! You’re right- the salted caramel drizzle really adds that something extra 🙂

  15. As you know, I can’t wait to make this for my 25th birthday! I was so excited when this recipe came through my inbox! My mom, sister, and I all love caramel cake-it’s definitely our favorite cake! Also, my mom and I are super excited that you use the caramel sauce in between the layers- we make that all the time- my mom evens eats it with a spoon! I’m excited to learn the technique of how to make the caramel syrup as well because I’ve never done that before! I love watching things form- one of my favorite things about baking as well as making memories with the ones you love! I also can’t wait for my great aunt to have a piece because she has always made the caramel cake in the family! Also, I can definitely believe that it took a year to perfect this caramel cake- caramel cakes are hard to master, but can be done! Thank you Sally- You definitely made my 25th birthday a huge hit with this caramel cake!

  16. I made this the other day and wow! I have found my go-to caramel cake! I left out the caramel drizzle, but made sure to add the toasted pecans for a different texture, and it was dynamite. Even my boyfriend (who usually prefers chocolate cake over any other flavor) said this was incredible, quickly eating forkfuls at a time. Loved this recipe, Sally, you’ve done it again!

  17. This cake was amazing!! I love the step by step instructions and the fact that if you follow them you can’t go wrong. I have never successfully made my own caramel before. The salted caramel was so easy to make and it turned out perfectly. I will be using this recipe as my go-to caramel sauce!! The cake was light and buttery, the frosting was the perfect salty/sweet combination and the burnt sugar syrup was delicious!
    Thank you, Sally, for your detailed instructions and the hours of testing you go through so that I, a home baker, can achieve professional results.

    1. Absolutely LOVE reading this, Laura! I’m so happy you were able to try making something new in the kitchen 🙂 So happy you enjoyed this recipe!

  18. Hi Sally,

    I baked this cake for an adult birthday party this weekend. It was incredibly easy to make and the perfect amount of sweet without being over the top. I have friends who don’t normally like buttercream but who loved this cake. I highly recommend to anyone who enjoys caramel flavor.

    The one baking modification I made was to use pure cane sugar as opposed to granulated sugar in the various parts of the recipe. I have been using your caramel recipe for years and the pure cane sugar resulted in the best caramel I’ve ever made. Not sure if that was the difference or if I was just on my baking game this time! 😉

  19. I have some of the salted caramel in my refrigerator now. I now it can be reheated in the microwave. Question…will it harden on the cake if the cake sits out at room temperature or will it stay soft?

    1. Hi Susan, Yes – reheat in the microwave! Just a few seconds at a time and stir each time so it heats evenly. This caramel will thicken but it will stay soft. Enjoy!

  20. This cake is so good! The cake layers are so soft and fluffy and they really melt in your mouth! The frosting is just delicious as well! We had some family over and I got so many compliments! Thank you so much for this amazing recipe!

  21. Hi!
    Made the cakes today hopefully ice them tomorrow can’t wait to try it!!
    Quick question can I add half cream and half milk in the frosting?

      1. Thank you very very much
        we all loved it will definitely be making it again x
        having trouble with the oven at the moment so made it in the airfryer the edges were a bit dry and hard do you have any experience with cakes in an airfryer? If you have any tips for me please!
