Stepwise Method: Triple Layer Cocoa Cake

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your cake will bake evenly.
Step 2: Prepare the Cake Pans
Grease and flour three 9-inch round cake pans. This will help the cake layers release easily after baking.
Step 3: Hydrate the Cocoa
In a small bowl, combine 1 cup of lukewarm water with the unsweetened cocoa powder. Stir until smooth, then set aside to cool slightly.
Step 4: Mix the Dry Ingredients
In a large mixing bowl, whisk together the cake flour, baking soda, granulated sugar, and brown sugar until well combined.
Step 5: Cream the Butter
In a separate bowl, beat the room-temperature butter with an electric mixer until creamy and light in color. This should take about 2-3 minutes.
Step 6: Add the Eggs
Add the eggs one at a time, mixing well after each addition. This will help ensure your batter is smooth and well-mixed.
Step 7: Combine Wet Ingredients
To the butter and egg mixture, add the buttermilk and the cooled cocoa mixture. Mix until fully combined.
Step 8: Combine Dry and Wet Ingredients
Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Be careful not to overmix; a few lumps are okay.
Step 9: Bake the Layers
Divide the batter evenly among the three prepared pans and smooth the tops. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Step 10: Cool the Cakes
Once baked, remove the cake layers from the oven and let them cool in the pans for 10 minutes. Then, transfer them to a cooling rack to cool completely.
Step 11: Frost and Assemble
Once the layers are completely cool, frost between the layers and on top using your favorite chocolate frosting. Enjoy a slice of your homemade Triple Layer Cocoa Cake!
Allergy-Friendly Substitutes

- Gluten-Free: Substitute cake flour with a gluten-free blend.
- Dairy-Free: Use coconut milk or almond milk instead of buttermilk and a plant-based butter alternative.
- Vegan: Replace eggs with flax eggs (1 tablespoon of ground flaxseed mixed with 3 tablespoons of water for each egg).
Notes from the Test Kitchen
For the best results, make sure your butter and eggs are at room temperature. This helps to create a smooth batter and a fluffy cake. If you want to enhance the chocolate flavor, consider adding a teaspoon of instant coffee to the cocoa mixture.
- Don’t skip the cooling step! Frosting a warm cake can lead to a melty mess.
- Make sure to sift your cocoa powder and flour for a lighter texture.
Keep-It-Fresh Plan
Your Triple Layer Cocoa Cake can be stored in an airtight container at room temperature for up to 3 days. For longer storage, wrap the cake layers tightly in plastic wrap and freeze for up to 3 months. Thaw in the refrigerator before frosting and serving.
Helpful Q&A
Can I make this cake ahead of time?
Absolutely! You can bake the cake layers a day in advance. Just be sure to wrap them well and store them in the fridge or freezer until you’re ready to frost and serve.
What can I use if I don’t have buttermilk?
You can make a quick substitute by adding 1 tablespoon of vinegar or lemon juice to a cup of milk. Let it sit for 5-10 minutes to curdle before using.
Can I use a different frosting?
Yes! This cake pairs wonderfully with cream cheese frosting, ganache, or even a simple whipped cream topping. Get creative!
How do I know when the cake is done baking?
The cake is done when a toothpick inserted in the center comes out clean or with a few moist crumbs. If it comes out wet with batter, give it a few more minutes in the oven.
