Step-by-Step Instructions
- Preheat your oven to 170ºC (340ºF) and line the bottoms of three 20 cm (8-inch) round cake pans with parchment paper.
- In a large mixing bowl, sift together all-purpose flour, cornstarch, granulated sugar, dark brown sugar, Dutch cocoa powder, baking powder, baking soda, and salt.
- In a separate bowl, whisk together the cooled black coffee, vegetable oil, sour cream, eggs, and vanilla extract until smooth.
- Carefully pour the wet mixture into the bowl of dry ingredients and gently fold everything together until just combined.
- Divide the batter evenly among the prepared cake pans and bake for 28-30 minutes.
- To prepare the coffee buttercream, beat the softened butter for 4 minutes, then gradually add the powdered sugar and instant espresso powder.
- Once the cake layers are cool, level the tops if necessary, then spread buttercream between layers and cover the cake.
