Method
- Preheat your oven to 350°F (177°C). Grease and line two 9-inch round cake pans with parchment paper.
- In a large bowl, whisk together the flour, cocoa powder, sugar, baking soda, baking powder, salt, and espresso powder.
- In another bowl, whisk together the vegetable oil, eggs, and vanilla extract. Stir in the buttermilk.
- Pour the wet ingredients into the dry ingredients and stir until just combined. Add the hot coffee or water and mix until smooth. The batter will be thin.
- Divide the batter evenly between the two prepared pans. Bake for 23–26 minutes or until a toothpick inserted in the center comes out clean.
- Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
- To make the frosting, beat the butter until creamy. Add powdered sugar, cocoa powder, cream, vanilla, and salt. Beat until light and fluffy.
- Frost the cooled cake layers with the chocolate buttercream. Garnish with chocolate chips if desired.
- Chill the cake for at least 30 minutes before slicing for clean cuts.
