Triple Layer Chocolate Cake


You will need three bowls to make this cake – two large and one medium in size.




How to Make a Chocolate Cake from Scratch




Mix the cocoa powder and boiling water in a medium bowl until well combined and no lumps remain.  




Chocolate Buttercream Frosting


Mix the butter and cocoa powder in a large bowl until well blended. Then add the powdered sugar and mix on low speed until all of the sugar is combined. Finally, stir in milk and vanilla extract to reach a smooth consistency.

Helpful Tips


  • To bring the eggs to room temperature quickly, let them sit in a bowl of warm water for 5 minutes.
  • Bake cakes a day prior for the easiest frosting. Just cover the baking pans with plastic wrap after they’ve cooled, and frost the next day.

Prep Time 20 minutes
Cook Time 28 minutes
30 minutes
Total Time 1 hour 18 minutes
Course Dessert
Servings 12 servings



  • 1 cup unsalted butter
  • cups granulated sugar
  • 4 large eggs room temperature
  • 2 tsp vanilla extract
  • 3 cups all-purpose flour
  • 2 tsp baking soda
  • 1 tsp baking powder
  • ½ tsp salt
  • 1 cup unsweetened cocoa powder
  • cups boiling water


  • 1 cup unsalted butter
  • ½ cup cocoa powder
  • 16 oz powdered sugar
  • 2 tbsp whole milk
  • 1 tsp vanilla extract


  • Preheat oven to 350°F. Grease and flour (3) 8” round cake pans, then line bottom with round parchment paper. Set aside.
  • Cream the butter and sugars in a large mixing bowl. Add in the eggs and vanilla and mix until well blended.
  • In a separate large mixing bowl, combine flour, baking soda, baking powder, and salt.
  • Mix the cocoa powder and boiling water in a medium bowl until well combined and no lumps remain.
  • Alternating between the two, slowly add dry ingredients and chocolate mixture to the bowl with the butter and sugar. Mix on low speed to incorporate ingredients.
  • Divide the cake batter evenly between the three cake pans and place in the pre-heated oven. Bake 22-28 minutes, or until toothpick inserted in the center of the cake comes out clean.
  • Remove from oven and set aside to cool for approximately 10 minutes before transferring the cakes from the pans to a wire rack to cool completely, approximately 20 more minutes. (Cakes should no longer be warm to the touch before frosting).
  • To assemble the cake, place the first layer top-side down on a cake plate. Add 1/3 of the frosting to the top of the cake layer and spread it out evenly. Take the second layer and level off the rounded top with a knife or cake leveler. Place the second layer on top of the first layer, top-side down. Add frosting to this layer and spread out evenly. Repeat this with the 3rd layer, and spread the remaining frosting out on the top layer.


  • Mix the butter and cocoa powder in a large bowl until well blended
  • Add the powdered sugar and mix on low-speed until all of the sugar is combined.
  • Stir in milk and vanilla extract to reach smooth consistency.
