Ingredients
Method
- Preheat oven to 350°F (180°C). Grease and line two 8-inch baking pans with parchment paper.
- In a large bowl, whisk together flour, cocoa powder, baking powder, baking soda, salt, and granulated sugar.
- Add eggs, buttermilk, oil, and vanilla extract; mix until almost combined.
- Stir in hot brewed coffee until the batter is smooth and lump-free.
- Divide batter evenly into prepared pans. Bake 25–30 minutes or until a toothpick inserted comes out clean. Cool completely.
- For frosting, beat butter and powdered sugar until smooth. Add cocoa powder, vanilla extract, and salt; whip 1–2 minutes.
- Add cold brewed coffee and melted chocolate to the frosting. Mix on high until whipped and smooth.
- Assemble cake: Place first layer on serving plate with a small frosting dot underneath. Brush layer with cold coffee for 1–2 minutes, then spread half of the buttercream evenly.
- Top with second cake layer, brush with coffee, and frost with remaining buttercream. Create wave pattern with an offset spatula. Serve and enjoy!
Notes
Use cake strips for even baking and allow the cake to cool completely before frosting to prevent melting. For stronger coffee flavor, increase coffee used for brushing.
