Devil’s Food Chocolate Cake… But Better

This pictured cake is a combination of chocolate buttercream and mock-devil’s food cake. You know the Devil’s Food chocolate cake you get at a restaurant or even from a box mix? This is that exact cake, only completely homemade. Notice the reddish tint? That’s where the name Devil’s Food comes from. The baking soda in this recipe reacts with the natural cocoa powder, which results in the reddish color. Gorgeous!

This chocolate cake is:

  • Extra moist
  • 2 layers, but can be made as a sheet cake
  • Soft with a velvety crumb
  • Deeply flavorful
  • Unapologetically rich
  • Covered with creamy chocolate buttercream

This is, without a doubt, the best chocolate cake I’ve ever had.

Chocolate Cake Ingredients

Each ingredient serves an important role. For best results, do not make substitutions.

  1. All-Purpose Flour: The structure of the cake. Use all-purpose flour– cake flour is too light.
  2. Unsweetened Natural Cocoa Powder: Do not use dutch-process cocoa powder. If desired, see dutch-process vs natural cocoa powder for more information.
  3. Baking Soda & Baking Powder: Use both baking soda and baking powder for lift.
  4. Salt: Salt balances the flavor.
  5. Espresso Powder: Espresso powder is optional, but I recommend its addition because it enhances the chocolate flavor. The chocolate cake will not taste like coffee.
  6. Oil: Don’t use butter in this cake batter. Cocoa powder is a particularly drying ingredient, so this cake needs oil for moisture.
  7. Eggs: Use 2 room temperature eggs. Place refrigerated eggs in a cup of warm water for 10 minutes to warm them up. Did you know what the temperature of your ingredients has a direct correlation to the success of your recipes. Unless otherwise noted, use room temperature ingredients.
  8. Buttermilk: This chocolate cake requires the moisture and acidity from buttermilk. Lately I’ve been using a mix of sour cream and buttermilk, as well as reducing the hot liquid (below). You can see that in my dark chocolate mousse cake, tuxedo cake, black forest cake, and German chocolate cake recipes.
  9. Vanilla Extract: Vanilla extract adds flavor.
  10. Hot Coffee or Hot Water: Hot liquid encourages the cocoa powder to bloom and dissolve. If you don’t drink coffee, you can use hot water. For deeper flavor, though, use coffee.

How to Make Chocolate Cake

What an easy chocolate cake! No mixer required for the batter, simply whisk the dry ingredients in one bowl and the wet ingredients in another bowl. Pour the wet ingredients into the dry ingredients (or vice versa, it doesn’t make any difference), add the hot coffee, then whisk everything together. The cake batter is thin. Divide between 2 9-inch cake pans. You can easily stretch it to 3 or 4 8-inch or 9-inch cakes if needed. Or make a quarter sheet cake using a 9×13 inch cake pan.

Chocolate Buttercream

I use my favorite chocolate buttercream recipe as the base, but slightly increase the amount of each ingredient to produce enough frosting for the layer cake. If you prefer a thinner layer of frosting, use the chocolate buttercream recipe. But if you crave extra buttercream, follow the frosting measurements below. You need 6 ingredients total:

  1. Unsalted Butter
  2. Confectioners’ Sugar
  3. Unsweetened Cocoa Powder
  4. Heavy Cream or Milk
  5. Vanilla Extract
  6. Salt

Because there is no leavening occurring, you can use either dutch-process or natural cocoa powder in the buttercream. Heavy cream provides an extra creamy frosting, but milk can be substituted if needed.

So, why do I call it triple chocolate layer cake when it only has 2 layers? Well, chocolate is used three times: chocolate cake, chocolate frosting, chocolate chip garnish. Let’s eat!

Triple Chocolate Layer Cake

Description

This is my favorite homemade chocolate cake recipe. With a super moist crumb and fudgy, yet light texture, this chocolate cake recipe will be your favorite too. Top with chocolate buttercream and chocolate chips for 3x the chocolate flavor. You can also prepare this chocolate layer cake as a sheet cake too. See recipe note.


Ingredients

  • 1 and 3/4 cups (220g) all-purpose flour (spoon & leveled)
  • 3/4 cup (65g) unsweetened natural cocoa powder*
  • 1 and 3/4 cups (350g) granulated sugar
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 2 teaspoons espresso powder (optional)*
  • 1/2 cup (120ml) vegetable oil (or canola oil, or melted coconut oil)
  • 2 large eggs, at room temperature*
  • 1 and 1/2 teaspoons pure vanilla extract
  • 1 cup (240ml) buttermilk*
  • 1 cup (240ml) freshly brewed strong hot coffee*

Chocolate Buttercream

  • 1.25 cups (2.5 sticks or 290g) unsalted butter, softened to room temperature
  • 34 cups (360-480g) confectioners’ sugar
  • 3/4 cup (65g) unsweetened cocoa powder (natural or dutch process)*
  • 35 Tablespoons (45-75ml) heavy cream (or half-and-half or milk)
  • 1/4 teaspoon salt
  • 1 teaspoon pure vanilla extract
  • optional for decoration: semi-sweet chocolate chips

Instructions

  1. 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.
  2. Make the cake: Whisk the flour, cocoa powder, sugar, baking soda, baking powder, salt, and espresso powder (if using) together in a large bowl. Set aside. Using a handheld or stand mixer fitted with a whisk attachment (or you can use a whisk) mix the oil, eggs, and vanilla together on medium-high speed until combined. Add the buttermilk and mix until combined. Pour the wet ingredients into the dry ingredients, add the hot water/coffee, and whisk or beat on low speed until the batter is completely combined. Batter is thin.
  3. Divide batter evenly between pans. Bake for 23-26 minutes or until a toothpick inserted in the center comes out clean. Baking times vary, so keep an eye on yours. The cakes are done when a toothpick inserted in the center comes out clean.
  4. Remove the cakes from the oven and set on a wire rack. Allow to cool completely in the pan.
  5. Make the buttercream: With a handheld or stand mixer fitted with a paddle or whisk attachment, beat the butter on medium speed until creamy – about 2 minutes. Add confectioners’ sugar, cocoa powder, heavy cream, salt, and vanilla extract. Beat on low speed for 30 seconds, then increase to high speed and beat for 1 full minute. Do not over-whip. Add 1/4 cup more confectioners’ sugar or cocoa powder if frosting is too thin or another Tablespoon of cream if frosting is too thick. Taste. Add more salt if needed. (I usually add another pinch.)
  6. Assemble and frost: If cooled cakes are domed on top, use a large serrated knife to slice a thin layer off the tops to create a flat surface. This is called “leveling” the cakes. Discard or crumble over finished cake. Place 1 cake layer on your cake stand or serving plate. Evenly cover the top with frosting. Top with 2nd layer and spread remaining frosting all over the top and sides. I always use an icing spatula and bench scraper for the frosting. Garnish with chocolate chips, if desired.
  7. Refrigerate cake for at least 30-60 minutes before slicing. This helps the cake hold its shape when cutting.
  8. Cover leftover cake tightly and store in the refrigerator for 5 days.

Notes

  1. Make Ahead & Freezing Instructions: Prepare cake through step 4. Wrap the individual baked and cooled cake layers tightly and refrigerate for up to 2 days or freeze up to 3 months. Bring to room temperature then continue with step 5. You can prepare the chocolate buttercream 2-3 days in advance. Cover and refrigerate, then bring to room temperature before spreading onto/assembling the cake. Frosted cake freezes well, up to 3 months. Thaw overnight in the refrigerator, then bring to room temperature or serve cold.
  2. 3 Layer Cake: You can also prepare this cake as a 3 layer cake. Divide batter between three 8-inch or 9-inch cake pans and bake for 22-25 minutes or until a toothpick inserted in the center comes out clean. This frosting will be enough for 3 layers. If desired for extra frosting, use the frosting recipe from my Piñata Cake.
  3. Cocoa Powder: Use natural cocoa powder in the cake, not dutch-process. (If desired, see dutch-process vs natural cocoa powder for more information.) Since there is no leavening occurring in frosting, you can use either natural or dutch-process in the chocolate buttercream.
  4. Buttermilk: Buttermilk is required for this recipe. You can make your own DIY version of buttermilk by measuring 1 Tablespoon of lemon juice or white vinegar in a measuring glass. Add enough milk (1%, 2%, or whole) in the same measuring glass to reach 1 cup. Stir it around and let sit for 5 minutes. The soured milk will be somewhat curdled and ready to use in your recipe. Lately I’ve been using a mix of sour cream and buttermilk, as well as reducing the hot coffee. You can see that in my dark chocolate mousse cake. That cake and this cake are both fantastically moist, but the sour cream version has a sturdier crumb.
  5. Room Temperature Ingredients: All refrigerated items should be at room temperature so the batter mixes together easily and evenly. Read here for more information.
  6. Espresso Powder/Coffee: Espresso powder and coffee will not make the cake taste like coffee. Rather, they deepen the chocolate flavor. I highly recommend them both. If coffee isn’t your thing, you can leave out the espresso powder and use extra hot water or hot chai tea.
  7. 9×13 Inch Pan: You can bake this cake in a 9×13 inch baking pan. Same oven temperature, about 35-40 minutes bake time.
  8. Chocolate Cupcakes: Here is my favorite chocolate cupcakes recipe. Same unbelievable texture as this cake! You can also use this cake batter for 2-3 dozen cupcakes. Same baking instructions as my chocolate cupcakes.

  1. This cake is absolutely delicious and I love the decorating with the chocolate chips, so pretty!!

  2. Oh my gosh Sally, my mouth is watering at this recipe! You’re right, you can’t mess with chocolate cake, and this recipe looks like a keeper! Love how moist it looks 😀 It must have tasted like chocolate heaven…yum!!

      1. Hello SAlly…I love your recipes i have a question I always have problem how to get the perfect heavy cream?is it the same with thick cream?

  3. Oh my goodness, Sally… You keep stunning me with one after another amazing creation! This cake looks soooo devilishly delicious! I’ve never found myself craving chocolate so bad so early in the morning, haha. Thanks for sharing! Have a happy Monday!

  4. I’ve been making the same chocolate fudge cake for thirty years now so I’m not allowed to switch. However this looks incredible and I’ll bet everyone in your office is thrilled!

  5. This is my kind of cake – just LOVE it! The cake itself looks so moist and the frosting is so creamy! The cake is very similar to my favorite recipe from Ina Garten, which is sorta like Hershey’s recipe but whatever you call it, it is such a great chocolaty moist cake. I can’t believe you made 3 cakes over the weekend to find the perfect one! That’s why I visit professional blogs like this so I can take a shortcut and go straight to the good stuff! Thank you! ; )

    1. Hey Monica! This cake is adapted from Ina! 🙂 Love Ina’s recipes so much. Yes three cakes – a lot of chocolate in the apartment over the weekend.

  6. This looks like a winner, especially since it has buttermilk AND coffee in it! I can never have enough good cake recipes.

  7. Sally, I LOVE using coffee in my chocolate cakes! And I can’t stand the taste of coffee…but I love the aroma, I’m weird like that. In fact, I have a coffee maker JUST to use the coffee for baking! But the coffee truly gives it a more intense taste with chocolate, other than just using plain water. AND, without tasting the coffee. Love everything about this cake! (You rock!)

  8. oh no! Poor Sally, having to sample 3 chocolate cakes in one weekend. Sounds like a really rough time 😉 I love the addition of coffee, I always love the way it develops chocolatey flavors

  9. I’m beyond obsessed with chocolate – I once gave a lecture on the history of chocolate to my 8th grade English class. I don’t think I was ever that motivated over any other subject in all my years of schooling. I HAD to come and read this post immediately upon seeing this pop up on my Bloglovin feed. Good God, Sally – I’d give my right arm for a slice of this cake! This should be how every Monday starts – the world would be a much happier place!

    1. hahaha I don’t think I’d ever be more motivated on anything besides peanut butter. So, I totally hear you on the chocolate lecture. 🙂

  10. You DO only give us the best of the best and we love you for it!! 😉 This looks sinful and delicious!!

  11. What have you done?! You’re totally torturing me here. You had me at the title and even the first pic but the third pic was over the top amazing. It looks so super moist and amazingly delicious. I must have a slice!

  12. This looks so beautiful Sally! I love that you decorated it with chocolate chips – such a cute idea! I hate it when I test a recipe a few times to get it right and have an excess of baked goods hanging around the house (not good for my waistline haha)

    PS – I LOVE your cake stand! It’s adorable!!

  13. By far and away, without a doubt, the prettiest thing you’ve ever made on your blog. You make lots of things that are pretty and look good and get my drooling, but this is the prettiest and most beautiful! It literally…takes the cake 🙂

    The amount of work that it takes to come up with a winning cake recipe is mindblowing. When I was writing PBC, I tested PB cakes until I couldn’t even taste them anymore. It was like…omg another.pb.cake. And then last year right after that, I came up with my own chocolate cake. After more research and trials. It takes ages!!! And lots of (wasted) chocolate. Some things are good enough to donate to others even if they’re not blog-able. But some things just get tossed.

    The choc chip spikes. So beautiful. Sally, so impressed! And your smooooooth frosting and decorating skills. Wonderful! Pinning!

    1. Thank you VERY much for the kind words Averie! That means a lot coming from you. I owe it to the new lens, new lighting, and just a pretty cake overall. Still getting used to the new light. This was one of the photoshoots I actually liked! Wasted chocolate, I am all too familiar with that after this weekend. Again… thank you!

  14. Hey Sally! Oh My Gosh……this looks soooo good!!! I shouldn’t be looking at this coming home from school with my stomach growling right now hahaha 😛 I really thought I had a “perfect chocolate cake recipe but I think I need to give this one a try for my parent’s anniversary that’s coming up soon!

  15. My cakes are in the oven right now!! The part im not looking forward to is the frosting! I really really really dont like making frosting! When I make birthday cakes I order butter cream online! 🙂 But for the love of chocolate I will do this and it will be great! BTW kitchen is still not clean, why its actually messier yah!

    1. Just finished decorating and taking pics of this cake, and here is what I know:

      1. In about 5 minutes I will be officially removing myself from anymore blog posts from sallysbakingaddiction.com

      2. The frosting alone on this thing is good enough to be considered a last meal choice on death row.

      3. I probably just made about 500 new BFFS after I just posted pics of the cake on Facebook.

      4. I will go to the gym tomorrow for about 8-10 hours after eating a piece.

      5. I WILL SHARE THIS CAKE WITH NO ONE, not even my 2 year old son or husband. Ok, my son can have some, he doest eat a lot anyway.

      ok ok only #2 is true! I haven’t cut into this cake yet, but I’m going to go ahead and make a guess that its better than it looks!!

      1. I got scared reading #1. But I am so glad you were only joking. So glad you loved this cake and the frosting – I know, it’s dangerously good! Share your pictures on my facebook page. I want to see it. Thanks Mary!

  16. Wow, Sally, your photographs are always incredible, but I think these are some of your best! The focus is great and I love how clean all your lines are. The chocolate chips look fabulous too, and for a largely brown post, the pictures are NEVER boring to look at. Great work! About the recipe…do you happen to know whether the make-your-own buttermilk thing works with almond milk?

    1. Thanks so much Caley! I got a new lens over the weekend, and this was my first photoshoot with it. (got the Canon 50mm 1.4). So glad you noticed the better quality photos, thank you for that! Unfortunately, you need dairy milk to replace the buttermilk when using the lemon juice/vinegar.

      1. There is a great product that I use whenever buttermilk is called for in a recipe. The brand is SaCo and it is a Cultured Buttermilk powder. You measure the dry powder and mix it with the rest of your dry ingredients, and then add the appropriate amount of water to the rest of the liquid ingredients. It can be stored in the refrigerator so that it is always ready to use. I find it in the baking aisle. It is so convenient; I never have to be concerned if I have real buttermilk on hand, or figure out what to do with the rest of the buttermilk that I didn’t need.

  17. I’d love to know what brands you use, especially when it comes to the coco and chocolate. I always worry that it’s the brand I choose that leaves my chocolate concoctions not so great. Please list for me!!!

    1. Hi Alison! I used Hershey’s unsweetened cocoa powder and Nestle dark chocolate morsels as the chocolate chips. Everything else really doesn’t need a name brand. Thank you!

  18. I really enjoy reading all your baking tips about why thinks work the way they do and what happens if you omit them. Baking really is a science and it’s so neat that things work out the way they do when the right ingredients are together. This cake look SUPER moist and chocolatey and dense. I really would adore a double portion of this 🙂

  19. Coffee in chocolate desserts is the best thing ever. LOVE this cake Sally! It’s gorgeous!

  20. OMG, what a gorgeous cake! I love adding coffee to my chocolate cakes, though I have to admit, it’s been far too long since I’ve made one. I think that’s going to have to change–soon. This looks perfect – you can see how moist it is from the pictures. LOVE!

  21. Oh Sally! This made my morning! My sweet husband (who never bakes) bakes a chocolate something for my birthday every year – later this month. I’ve been on the fence about what I want this year – brownies or chocolate cake, but you may be tipping the scales in favor of cake with this one! The texture of the cake looks perfect!

  22. Love this cake! Defo death by chocolate! And I love that you used buttermilk, I never really used buttermilk till this weekend- used it in 2 recipes and I definitely pondered about it in a chocolate cake and here we are! So funny! The milk chocolate frosting looks like I could take a spoon to it! Drool!

  23. I have to try this recipe. I’m very picky about chocolate cake recipes because my grandmother passed down such a fabulous one. This one sounds like it may be as fabulous as my grandmother’s. You are absolutely right about buttermilk in cakes. My grandmother swore by it, and told me never to make a cake without buttermilk in it. I tried recipes without it, and found out she was correct.

    One thought about the vegetable oil. If anyone is concerned about genetically modified (GMO) food, make sure to get a vegetable oil that is certified organic. And stay away from canola oil if GMO is something you want to avoid. Most canola in the U.S. is GMO.

    And if you are concerned about artificial color, find food dyes that are natural. As someone with ADD, I avoid artificial colors and flavors like the plague.

  24. Sally, I am positive that everyone in my house would go crazy for this cake!! OMG, I would kill for a slice…..or 3!
