Ingredients

  • FOR CUPCAKES
  • 2 cups Flour
  • 1/2 teaspoons Baking Soda
  • 1 teaspoon Baking Powder
  • 1/4 teaspoons Salt
  • 1/2 cups Butter
  • 1-3/4 cup Sugar
  • 1 teaspoon Vanilla
  • 4 whole Egg Whites
  • 1-1/2 cup Sour Milk
  • 1-1/2 cup Oreo Pieces, Finely Chopped
  • FOR FROSTING:
  • 1-1/2 stick Butter
  • 3/4 cups Shortening
  • 1-1/2 teaspoon Vanilla
  • 6 cups Powdered Sugar
  • 3 Tablespoons Milk
  • 1 cup Oreo Pieces, Finely Ground

Method

  • For the cupcakes, preheat the oven to 350 degrees. Mix together the flour, baking soda, baking powder, and salt in a medium bowl.
  • In a large bowl, cream the butter with the sugar and vanilla.
  • Add the egg whites, half at a time. The mixture will go from crumbly to soupy.
  • Add half of the flour mixture and then half of the sour milk to the butter mixture, mixing until well-blended. Repeat with the remaining halves of each. The mixture should now have a normal cake batter consistency.
  • Stir in the Oreo pieces.
  • Pour the batter into two cupcake paper-lined cupcake pans (24 cupcakes total). Bake for about 20 minutes, or until a knife inserted in the center comes out clean. Cool completely before frosting.
  • While you're waiting for the cupcakes to cool, make the frosting. First, cream together the shortening, butter, and vanilla. Add in the powdered sugar 2 cups at a time. Then, add in the milk, and mix until well-blended. Finally, mix in the Oreo pieces.
  • Spread on the cupcakes with a knife, or pipe on with a frosting bag.
