🥣 How to Make It
This chocolate cake is much simpler to prepare than it looks. You’ll need 13 basic ingredients and about 1 hour from start to finish.
For the cake layers, you’ll need:
Start by whisking together all of the dry ingredients in a large bowl. Then, add the wet ingredients and whisk until the batter is smooth and glossy.
Lightly grease and line three 6-inch cake pans with parchment paper. Divide the batter evenly between the pans and bake for about 20 minutes. The tops of the cakes should be just slightly cracked, and a toothpick inserted into the center should come out almost clean.
Let the chocolate cake layers cool completely at room temperature before frosting.
The frosting is incredibly simple to prepare. Simply beat the softened vegan butter with cocoa powder, powdered sugar, almond milk, vanilla extract, and a pinch of salt until it becomes light and fluffy.
To assemble, spread a generous amount of the frosting on top of the first chocolate cake layer and repeat the process. Finish by frosting the top and sides of the cake, then garnish with shaved chocolate or your favorite decorations.
📔 Pro Tips for Success
Use room temperature ingredients.
Make sure your plant-based milk and vegan butter are at room temperature before you start. This helps everything combine smoothly for a perfectly textured cake.
Don’t overmix the batter.
Mix just until the ingredients are combined. Overmixing can develop too much gluten, resulting in a dense, tough cake instead of a light, fluffy one.
Level your cake layers.
If your cake layers have domed tops, use a serrated knife to level them off before frosting. This ensures a stable, professional-looking final cake.
Chill before slicing.
For clean, neat slices, refrigerate the finished cake for at least 30 minutes before cutting. This helps the frosting set and prevents crumbling.
💬 Frequently Asked Questions
Can I make this cake gluten-free?
While I haven’t tested it myself, I believe a 1:1 gluten-free flour blend should work well as a substitute. Just make sure to use a blend specifically designed for baking.
Can I use a different frosting?
Absolutely! You can easily swap the buttercream for a cashew-based chocolate frosting, a chocolate ganache, or even a coconut cream frosting for a lighter option.
How long does this cake keep?
This layer cake will stay fresh for up to 5 days when stored in the refrigerator. Be sure to remove it from the fridge 30-40 minutes before serving to allow it to come to room temperature for the best flavor and texture.

Yes! You can freeze the unfrosted cake layers for up to 3 months. Wrap them tightly in plastic wrap and then foil. When ready to use, thaw overnight in the refrigerator before frosting.

- 1/2 tsp baking soda
- 1/2 tsp salt
- 1 cup plant-based milk (soy, oat, or almond)
- 1/2 cup melted coconut oil (or vegetable oil)
- 1/4 cup unsweetened applesauce

- 1/2 cup unsweetened cocoa powder
- 2-3 tbsp plant-based milk
- 2 tsp vanilla extract

For Garnish
- Chocolate shavings or curls
- Fresh berries (optional)
Instructions
- Preheat and prepare: Preheat your oven to 350°F (175°C). Grease and line three 6-inch cake pans with parchment paper.
- Mix dry ingredients: In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- Combine wet ingredients: Add the plant-based milk, melted coconut oil, applesauce, vanilla extract, and apple cider vinegar to the dry ingredients. Whisk until the batter is smooth and well combined. The batter will be quite thin—this is normal.
- Bake: Divide the batter evenly among the prepared cake pans. Bake for 18-22 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
- Cool: Allow the cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
- Make the frosting: In a large mixing bowl, beat the softened vegan butter until creamy and smooth. Gradually add the sifted powdered sugar and cocoa powder, beating until combined. Add the plant-based milk, vanilla extract, and salt, and continue beating until light and fluffy (about 3-4 minutes).
- Assemble: Once the cakes are completely cool, level the tops if needed. Place one layer on a serving plate and spread a generous layer of frosting on top. Repeat with the second and third layers.
- Frost and decorate: Use the remaining frosting to cover the top and sides of the cake. Garnish with chocolate shavings, berries, or your favorite decorations.
- Chill and serve: Refrigerate for at least 30 minutes before slicing for clean, neat pieces.
Notes
- Pan size: If using 8-inch cake pans, reduce the baking time by 2-3 minutes.
- Storage: Store in the refrigerator for up to 5 days. Bring to room temperature before serving.
- Freezing: Unfrosted cake layers can be frozen for up to 3 months. Thaw overnight in the refrigerator before frosting.
