How to Make Mocha Fudge Layer Cake
Mix the Batter
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
- Add the buttermilk, vegetable oil, eggs, and vanilla extract to the dry ingredients. Mix until just combined—no over-mixing!
- Carefully pour in the hot brewed coffee and stir until smooth. The batter will be thin—that’s exactly how it should be.
Bake the Cakes
- Divide the batter evenly between both cake pans.
- Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
- Cool the cakes in their pans for 10 minutes, then turn onto wire racks to cool completely.
Make the Mocha Fudge Frosting
- In a medium bowl, beat together the softened butter and cocoa powder until smooth.
- Gradually add the powdered sugar, alternating with splashes of brewed coffee, until the frosting reaches your desired creamy consistency.
- Mix in the vanilla extract.
Assemble the Cake
- Place the first cake layer onto a serving plate. Spread a generous layer of frosting on top.
- Add the second cake layer. Frost the top and sides with the remaining mocha fudge frosting.
- Garnish with chocolate shavings or a dusting of cocoa powder, if desired.

Tips for Success
- Ensure the coffee is hot when added—it helps bloom the cocoa for deeper flavor.
- If your cakes dome on top, gently level them with a serrated knife before frosting.
- For an ultra-smooth finish, apply a “crumb coat,” chill for 20 minutes, then add the final frosting layer.
- Use room-temperature ingredients for the best mixing and texture.

FAQs
Can I make this cake ahead of time?
Yes! Bake the layers up to 2 days in advance, wrap tightly, and store at room temperature.
Can I freeze the cake?
Absolutely. Freeze frosted or unfrosted layers for up to 2 months. Thaw in the refrigerator.
Do I have to use coffee?
Coffee intensifies the chocolate flavor but doesn’t make the cake taste like coffee. You can substitute hot water if needed.
Can I use a different frosting?
Yes—cream cheese frosting, whipped ganache, or classic buttercream all work well.
My frosting is too thick/thin. What should I do?
Add more coffee (or milk) a tablespoon at a time to thin, or extra powdered sugar to thicken.
Can I bake this in one pan instead of two?
Yes, use a 9×13 pan and increase baking time to 40–45 minutes.
