Ingredients

For the Cake:

  • 2 cups granulated sugar
  • 1 & 3/4 cups all-purpose flour
  • 3/4 cup cocoa
  • 1 & 1/2 teaspoons baking powder
  • 1 & 1/2 teaspoons baking soda
  • 1 teaspoon salt
  • 2 large eggs
  • 1 cup milk
  • 1/2 cup vegetable or canola oil
  • 2 teaspoons vanilla
  • 1 cup boiling water

For the One Bowl Chocolate Frosting

  • 6 tablespoons butter softened to room temperature
  • 2 & 2/3 cups confectioner’s powdered sugar
  • 1/2 cup cocoa
  • 1/3 cup heavy whipping cream
  • 1 teaspoon pure vanilla extract

Instructions

For the cake:

  • Preheat oven to 350 degrees F.  Grease and flour two 9-inch cake rounds or one 13×9x2-inch baking pan.
  • In a large mixing bowl, stir together the first six ingredients (sugar through salt); add eggs, milk, oil and vanilla; beat on medium speed for 2 minutes. Stir in boiling water (batter will be thin); pour into prepared pan(s) and bake in a preheated 350 degree F oven for 35-40 minutes or until a toothpick inserted in center comes our clean. If baking cake rounds, allow rounds to cool slightly before turning out onto wire racks to cool completely. If using rectangular baking pan, allow cake to cool completely before icing.

For the frosting

  • In a medium-sized bowl, mix and beat all ingredients using an electric mixer. If icing seems too thick, add a touch more heavy cream until desired consistency is reached, taking care not to over-thin the icing. I have found these amounts enough to frost the top and center layer of two, stacked, 9-inch cake rounds (but not the sides) or the top of a 13×9x2-inch rectangular cake. If you are looking to frost the sides of the stacked cake rounds as well, consider doubling these amounts.
