Ingredients
For the cake
  • 1 cup flour
  • ¼ cup unsweetened cocoa powder
  • ¾ tsp baking soda
  • ½ tsp baking powder
  • ¼ tsp salt
  • 1 cup granulated sugar
  • 1 egg (at room temperature)
  • 1 tsp vanilla extract
  • ½ cup oil
  • ½ cup buttermilk
  • ½ cup freshly brewed warm coffee
For the buttercream frosting
  • ½ cup softened unsalted butter
  • 1½ cup powdered sugar (sifted)
  • ¼ cup unsweetened cocoa powder (sifted)
  • 2-3 tbsp milk
  • 1 tsp vanilla extract
Instructions
For the cake
  1. Preheat oven to 350 degree F. Line an 8-inch square or 9-inch round baking pan with parchment paper, apply butter to grease the pan and set aside.
  2. In a medium bowl, combine dry ingredients by sifting flour, cocoa powder, baking soda, baking powder and salt. Set aside.

  3. In the bowl of a stand mixer fitted with a paddle attachment, beat granulated sugar and egg until combined, followed by adding vanilla extract and oil.

  4. Add the dry ingredients alternating with buttermilk and beat until they combine well. Add warm coffee and beat well for one last time, the batter will be loose/watery/runny.
  5. Pour into the prepared pan and bake for 30-35 mins or until a toothpick inserted in the center comes out clean.
  6. Unmold the cake carefully to a wire rack and allow it to cool completely.
For the buttercream frosting
  1. In the bowl of a stand mixer fitted with a paddle attachment, beat butter until creamy. Add sifted cocoa powder, powdered sugar and vanilla extract, beat until it turns out smooth.
  2. Add milk as needed for desired consistency. Make sure your frosting is not runny or too thick, it should be spreadable.
  3. If the frosting seems loose, refrigerate it for some time to thicken.
  4. Spread the frosting over the cooled cake and style as desired.
Notes
  • If your cake feels dry or crumbly after baking, brush some simple sugar syrup over the cake to retain it moistness and texture.
  • Grease your pan properly to avoid any cracks or holes in your cake. This helps the cake to slide through the sides of the pan easily.
