  • 2 3/4 cups 12.4 ounces all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1 cup 8 ounces unsalted butter, room temperature
  • 2 teaspoons vanilla
  • 2 cups granulated sugar

  • 1/2 cup 4 ounces unsalted butter, softened
  • 2/3 cup unsweetened cocoa powder
  • 2 1/2 to 3 cups of confectioners' sugar
  • Pinch of salt
  • 1/4 cup sour cream
  • 2-4 tablespoons of milk or as needed


  • Preheat the oven to 350 degrees F. Spray two 9x2 -inch metal cake pans with flour-added baking spray or grease with butter/shortening and flour.
  • Mix together the flour, baking powder and salt and set aside.
  • In a stand mixing bowl, beat the butter on medium high speed until light and creamy. Beat in the vanilla.
