Instructions
- Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. In a large bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined.
- In a separate bowl, combine buttermilk, vegetable oil, eggs, and vanilla extract. Beat until smooth. Gradually add the wet ingredients to the dry ingredients, mixing on medium speed for about 2 minutes until well combined.
- Slowly pour in the hot coffee while mixing on low speed. The batter will be thin - this is normal! The coffee enhances the chocolate flavor without making the cake taste like coffee.
- Divide the batter evenly between the prepared pans. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Cool in pans for 10 minutes, then turn out onto wire racks to cool completely.
- While cakes cool, beat softened butter until creamy. Gradually add powdered sugar and cocoa powder, mixing until smooth. Add heavy cream, vanilla, and salt, beating until light and fluffy (about 3-4 minutes).
- Place one cake layer on a serving plate. Spread with about ¾ cup of frosting. Top with second layer and frost the top and sides with remaining frosting. For a professional look, use an offset spatula to create smooth sides and decorative swirls on top.
Notes
Ensure eggs, buttermilk, and butter are at room temperature for best texture. Don't overmix ingredients. Hot coffee intensifies chocolate flavor - don't skip it! Make sure cakes are completely cool before frosting to prevent melting.
