- 1 3/4 cups all-purpose flour
- 2/3 cup cocoa powder
- 1 1/2 cups sugar
- 1 1/2 tsp baking soda
- 1 tsp baking powder
- 1 tsp salt
- 2 eggs, at room temperature
- 2/3 cups buttermilk
- 1/2 cup vegetable oil
- 1 tbsp vanilla extract
- 1 cup hot brewed coffee
- 1 cup salted butter, softened
- 1/2 cup cocoa powder
- 2-3 cups powdered sugar
- 1/2 tsp vanilla extract
- 2 tbsp heavy cream or milk
- Preheat oven to 350F and grease a 9×13 inch sheet pan with nonstick cooking spray.
- In a large bow, stir together the flour, cocoa powder, sugar, baking soda, baking powder and salt. Set aside.
- In a separate bowl, whisk together the eggs, buttermilk, vegetable oil and vanilla.
- Stir the wet ingredients into the flour mixture and mix until just combined.
- Pour in the hot coffee and stir until fully incorporated.
- Pour the batter into the prepared pan and bake for 30 minutes, until a toothpick inserted in centre of cake comes out clean. Cool cake on wire rack.
- For the frosting: in the bowl of an electric mixer fitted with the paddle attachment or using a hand mixer, whip the butter until light and fluffy and almost doubled in volume. This should take about 10 minutes.
- Reduce mixer speed to low and add in the vanilla, heavy cream and cocoa powder. Mix until combined.
- Next, slowly add in the powdered sugar, half a cup at a time, until desired consistency is reached. Use an offset spatula to spread frosting on completely cooled cake.
