Ingredients

Cake

  • 1 cup all-purpose flour
  • 1 cup granulated sugar
  • ¼ cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • ¼ teaspoon salt
  • 1 large egg
  • ½ cup vegetable oil
  • ½ cup buttermilk, (see note)
  • ½ cup hot water

Frosting

  • ¼ cup unsalted butter
  • 1 tablespoon unsweetened cocoa powder
  • 2-3 tablespoons milk
  • ½ teaspoon vanilla extract
  • cups powdered sugar, sifted
  • sprinkles for topping, optional

Instructions

  • Preheat oven to 350°F. Grease an 8x8 cake pan with cooking spray.
  • In a large bowl, whisk the flour, sugar, cocoa, baking soda, baking powder and salt.
  • Add egg, oil, buttermilk and hot water and beat until the batter is smooth.
  • Pour into the prepared pan and bake for 26-28 minutes or until a toothpick inserted into the middle comes out clean.

Frosting

  • Melt butter in a medium pot over low heat. Add cocoa powder, milk and vanilla and whisk until smooth. Add powdered sugar and whisk until smooth.
  • Remove from the heat and pour over the warm cake. Spread frosting quickly and add sprinkles right away, since frosting sets up quickly.
