The Necessities:


  • 12 tbsp butter, softened/room temperature
  • 1 3/4 cup sugar
  • 3 cup flour, sifted
  • 2 tsp baking powder
  • 1 tsp baking soda
  • Pinch salt
  • 1 tbsp cocoa powder
  • 3 eggs, room temperature
  • 1 tsp vanilla
  • 1 cup buttermilk
  • 1/2 cup strong coffee
  • 2 tsp instant espresso powder

Mocha Buttercream 

  • 2 ½ sticks butter, softened/room temperature
  • 3 cup powdered sugar
  • 1 tbsp cocoa powder
  • ¼ cup strong coffee
  • 2 tsp instant espresso powder
  • 1 tsp vanilla
  • ¼ c grated good dark chocolate (ie. Scharffen Berger 70%)
  • 1 tbsp coffee beans (optional)
  • 1 tbsp cocoa nibs (optional)
  • Additional powdered sugar for dusting (optional)


  • Preheat oven to 350F (325F if using a glass pan). Butter and flour a 9 x 13 sheet pan, set aside.
  • Cream butter and sugar in a stand mixer until pale and fluffy.
  • Meanwhile, whisk together flour, baking powder, backing soda, salt, and cocoa in a separate bowl.
  • In another bowl (or measuring cup) combine vanilla, buttermilk, espresso powder, and coffee.
  • Add one egg at a time to the butter/sugar mixture and mix in completely before adding each remaining egg.
  • When the eggs are fully combined, add the dry and wet ingredients in intervals.
  • Start by adding 1/4 of the dry, then 1/3 of the wet – ending with dry ingredients.
  • Scrape down the sides of the mixer occasionally and turn off the mixer when adding the dry ingredients to avoid being covered in a cloud of flour.
  • Once the last of the dry ingredients are mixed in and the batter is smooth (don’t over mix!), transfer it to the buttered and floured (or buttered and parchment covered) ½ sheet pan.
  • Evenly spread the batter across the pan.
  • Bake for 25 minutes until the top of the cake springs back when touched or a toothpick inserted into the center comes out clean. Remove from oven to cool.
  • While the cake is out of the oven, move onto the frosting.
  • Beat butter until creamy. Add sugar and beat until creamy.
  • Dissolve the 2 tsp of espresso powder into the strong coffee and vanilla.
  • Add to butter and sugar and beat until combined.
  • Add remaining ingredients and beat until light and fluffy.
  • Spread the frosting over the cool cake.
  • Grind the coffee and cocoa nibs to a fine dust in a coffee grinder.
  • Sift the grounds lightly over the frosted cake.
  • Then sift the extra powdered sugar over the cake.
  • Slice and enjoy.
