Triple Chocolate Cake

This is my favorite homemade chocolate cake recipe. With a super moist crumb and fudgy, yet light texture, this chocolate cake recipe will soon 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.

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.

This is, without a doubt, the best chocolate cake I’ve ever had. And judging by your feedback in the reviews, I’m confident you’d say the same thing!


This Chocolate Cake Is:

  • Extra moist
  • 2 layers, but can be made as 3 layers or as a sheet cake
  • Soft with a velvety crumb
  • Deeply flavorful
  • Unapologetically rich, just like my flourless chocolate cake
  • Covered with creamy chocolate buttercream

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. Do not use cake flour– when combined with ultra-light cocoa powder, cake flour is too fine.
  2. Unsweetened Natural Cocoa Powder: Do not use dutch-process cocoa powder. If you’re interested, see dutch-process vs natural cocoa powder for an in-depth explanation.
  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, I promise. I use espresso powder in my chocolate zucchini cake, too!
  6. Oil: Don’t use butter in this cake batter. Cocoa powder is a particularly drying ingredient, so this cake needs oil for suitable moisture.
  7. Eggs: Use 2 room temperature eggs. To speed up the gently warming, place refrigerated eggs in a cup of warm water for 10 minutes. 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. You can read more about this next and see 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 enhances the cocoa powder’s flavor. It also encourages it to bloom and dissolve appropriately. You’ll notice I don’t use hot liquid in my chocolate cupcakes recipe. That’s because there isn’t the same volume of dry ingredients. With this amount of cake batter, we need a hot liquid to break up the cocoa powder lumps resting in all that flour. If you don’t drink coffee, you can use hot water. For deeper and darker flavor, though, use coffee. (Decaf coffee works!)

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. See my recipe notes for details.

Lately I’ve Been Using Sour Cream

As mentioned above and in the video tutorial, there are two ways to prepare this cake batter and the slight difference involves the wet ingredients. You can follow the recipe as written using buttermilk and hot coffee/water. Or you can add sour cream. Whichever way you make it, the process is the same. (Just reduce the liquids and add sour cream!)

  1. Original Version (pictured and written below): The original recipe produces a very thin batter. The cake is extra soft with a deliciously spongey texture.
  2. Sour Cream Version (written in recipe notes and shown in video tutorial): By replacing some of the buttermilk and hot coffee with sour cream, the cake batter is slightly thicker and produces a slightly denser cake with more structure. I love using sour cream in my vanilla cake, too!

Both cakes are equally moist and chocolatey with the same flavor and ease of preparation. It just depends if you want a spongier cake or not. 🙂

Chocolate Buttercream

Like my yellow cake, I use my favorite chocolate buttercream. I slightly increase the amount of each ingredient to produce extra frosting. 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*
  • 2 teaspoons pure vanilla extract
  • 1 cup (240ml) buttermilk*
  • 1 cup (240ml) freshly brewed strong hot coffee (regular or decaf)*

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), at room temperature
  • 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. (Note: Even if they’re completely done, the cooled cakes may *slightly* sink in the center. Cocoa powder is simply not as structurally strong as all-purpose flour and can’t hold up to all the moisture necessary to make a moist tasting chocolate cake. It’s normal!)
  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 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 up to 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, use the frosting recipe from my Piñata Cake if you want extra frosting.
  3. Cocoa Powder: Use natural cocoa powder in the cake, not dutch-process. (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 if needed. Add 2 teaspoons of white vinegar or lemon juice to a liquid measuring cup. Then add enough whole milk to the same measuring cup until it reaches 1 cup. (In a pinch, lower fat or nondairy milks work for this soured milk, but the cake won’t taste as moist or rich.) Stir it around and let sit for 5 minutes. The homemade “buttermilk” will be somewhat curdled and ready to use in the recipe.
  5. Sour Cream Version: Lately I’ve been using a mix of sour cream and buttermilk, as well as reducing the hot coffee. Reduce the buttermilk and hot coffee to 1/2 cup (120ml) each. Add 3/4 cup (180g) of full-fat room temperature sour cream with the wet ingredients. You can see this described above, in the video tutorial, and in my dark chocolate mousse cake. That cake and this cake are both fantastically moist, but the sour cream version has a slightly sturdier crumb.
  6. FAQ: The sour cream version (note above) makes a sturdy enough cake that will hold under fondant.
  7. Amount of Cake Batter: This recipe (and the sour cream version) yields about 6 cups of batter, which is helpful if you need it for different Cake Pan Sizes & Conversions.
  8. Room Temperature Ingredients: All refrigerated items should be at room temperature so the batter mixes together easily and evenly. Read here for more information.
  9. Espresso Powder/Coffee: Espresso powder and coffee will not make the cake taste like coffee. Instead, they deepen the chocolate flavor. I highly recommend them both. You can use the same amount of instant coffee (the powder) instead of espresso powder if desired. If coffee isn’t your thing, you can leave out the espresso powder and use extra hot water or hot chai tea.
  10. Bundt Pan: I recommend my chocolate cream cheese bundt cake but without the cream cheese filling. Reduce buttermilk in that recipe to 1/4 cup and increase sour cream to 1 cup.
  11. 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.
  12. Chocolate Cupcakes: Here is my favorite chocolate cupcakes recipe. Same unbelievable texture as this cake! (You’ll notice I don’t use hot liquid in that recipe. That’s because there isn’t the same volume of dry ingredients to break up. If you need more than 1 dozen chocolate cupcakes, use this chocolate cake recipe for 2-3 dozen. Same baking instructions as my chocolate cupcakes.

    I baked your chocolate cupcakes at the weekend and they were delicious so I am planning to use your chocolate cake recipe when I make my wedding cake. It needs to be 10″ round so I wondered if you could give me any suggestions on how much the quantities should increase by?

    Also, thanks for including the quantities with grams as well as cups! Very helpful as I am in the UK

    1. Stephanie @ Sally's Baking Addiction says:

      Hi Sarah, We are so happy you enjoyed the cupcakes! We haven’t made this cake in a 10 inch pan. To calculate how much batter to use for different size pans see the post Cake Pan Sizes & Conversions.

      1. Thanks so much for getting back to me so quickly! I will do a practice cake anyway so will see how it goes!

  2. Just baked this recipe. AWESOME! I had doubts when I saw that there is NO butter in this recipe. It turned out to be absolutely fluffy and chocolatey (really, no coffee taste). It’s so springy and fluffy that I’m worried it won’t work with the cake I’m making though because it won’t be stackable. I’m making a firetruck that basically is a big rectangle ( height 15cmx length 43cmx depth 12cm). And I made this recipe with a 13″x9″ sheet pan and got ~3 cm thickness rise from this cake. So, I’m guessing I’ll need around 4 of these layers and ~1cm buttercream between these layers which brings me to a total of 15cm height for my cake. Since I have to stack 3 layers of cake do you think this recipe is still suitable or I should try a more dense cake to withstand the weight?? This is my second time baking, I’d appreciate if you could help.
    Nonetheless, this is an amazing cake just to eat plain (that’s what I’m doing as I type this comment).

  3. It’s a fab recipe, so satisfying. Won’t be the only time am making it. My perfect chocolate cake. Thank you so much Sally xxx
