Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and prepare three round baking pans by greasing and lining with parchment paper.
- In a large mixing bowl, whisk together flour, cornstarch, cocoa powder, baking powder, baking soda, and salt until well combined.
- In another bowl, combine brewed coffee, vegetable oil, sour cream, eggs, and vanilla extract; mix until smooth.
- Gradually add dry ingredients to wet ingredients, folding together gently until just combined.
- Divide batter evenly between prepared pans and bake for about 30 minutes, until a toothpick inserted comes out clean.
- Let cakes cool in pans for 10 minutes, then turn out onto a wire rack to cool completely.
- Beat room-temperature unsalted butter until creamy, then gradually mix in sifted powdered sugar, cooled coffee, and vanilla until fluffy.
- Assemble the cake by layering with buttercream in between and frosting the top and sides.

Notes
For a bolder coffee flavor, consider adding instant espresso powder. Ensure wet ingredients are at room temperature for the best texture.
