Instructions
Preheat and Prepare Pans
Preheat your oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper. Lightly dust with cocoa powder for easy release.
Mix Dry Ingredients
In a large mixing bowl, sift together the flour, dark cocoa powder, sugar, baking powder, baking soda, and salt. Whisk to combine.
Add Wet Ingredients (Except Coffee)
Add the eggs, buttermilk, vegetable oil, and vanilla extract to the dry mixture. Beat on medium speed until well combined and smooth.
Incorporate Hot Coffee
Slowly pour in the hot coffee while mixing on low speed. The batter will be thin, which is perfect—it makes the cake moist and tender.
Divide and Bake
Evenly divide the batter between the prepared pans. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean. Let cakes cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
Make the Ganache Filling
While the cakes are cooling, prepare the ganache. Heat the heavy cream in a small saucepan until it just begins to simmer. Pour it over the chopped chocolate and let sit for 1–2 minutes. Stir until smooth. Stir in butter for added gloss, if desired. Cool to room temperature until spreadable.
Prepare Chocolate Buttercream
In a large bowl, beat the softened butter until creamy. Gradually add the powdered sugar and cocoa powder, mixing on low. Add vanilla extract and heavy cream. Beat until light and fluffy, adding more cream if needed.
Assemble the Cake
Place one cake layer on a serving plate or cake board. Spread a layer of ganache evenly over the top. Repeat with the second layer. Top with the third cake layer and gently press down.
Frost and Decorate
Cover the entire cake with the chocolate buttercream frosting. Use an offset spatula to smooth the top and sides. For a cleaner look, chill the cake for 15 minutes before applying a final smooth coat of frosting. Decorate as desired chocolate shavings, sprinkles, or more ganache drizzled on top work beautifully.
Notes
Notes:You can make the cake layers a day in advance. Wrap in plastic and refrigerate. Don’t skip the hot liquid it helps bloom the cocoa for a richer chocolate flavor. For a mocha twist, use espresso instead of coffee. If you’re in a hot climate, chill the cake slightly before slicing for cleaner cuts.
