Method
- Preheat oven to 350°F (175°C). Grease two 9-inch round cake pans and line the bottoms with parchment paper.
- In a large bowl, sift together flour, sugar, cocoa powder, baking powder, baking soda, and salt. Whisk to combine evenly.
- Add buttermilk, oil, eggs, and vanilla extract. Mix until just combined. Do not overmix.
- Slowly pour in boiling water or hot coffee while mixing on low speed. The batter will be thin.
- Divide batter evenly between prepared pans. Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.
- Let cakes cool in pans for 10–15 minutes, then transfer to a wire rack to cool completely.
- To make frosting, beat softened butter until smooth and creamy.
- Add cocoa powder and mix well.
- Gradually add powdered sugar, mixing on low speed.
- Add milk and vanilla extract. Beat until light and fluffy.
- Place one cake layer on a plate, spread frosting evenly on top, then place second layer over it.
- Frost the top and sides of the cake. Slice and serve.
