Ingredients
  

For the cupcakes:

  • 1 box 15.25 oz white cake mix
  • 1 c all-purpose flour sifted
  • 1 c granulated sugar
  • ¾ t salt
  • 1 1/3 c water
  • 1 c sour cream
  • 4 large egg whites
  • 2 T vegetable oil
  • 1 t vanilla extract

For the buttercream frosting:

  • 1 c 2 sticks unsalted butter, at room temperature
  • 3 c powdered sugar
  • 1 t vanilla extract
  • 2 t heavy whipping cream

Instructions
 

  • Preheat oven to 325F. This recipe makes about 36 cupcakes when filled ¾ with batter. Prepare the pans with the cupcake liners. Be sure all of your butter is soft (but not melted).
  • Sift the flour and cake mix into a large mixing bowl, then whisk in the sugar and salt.
  • Add the water, sour cream, egg whites, vegetable oil, and vanilla. Beat with an electric mixer on low speed just until combined.
  • Scoop the batter into the prepared muffin pans, filling each about ¾ full.
  • Bake at 325F for 18 minutes, until a toothpick inserted into the center comes out clean.
  • Cool in the pan for 2 to 3 minutes, then transfer to a wire rack to cool completely before frosting.
  • For the frosting, in a large mixing bowl, beat the 2 sticks of softened butter with an electric mixer on medium speed until smooth.
  • Beat in the powdered sugar on low speed, 1 c at a time, until combined.
  • Add the vanilla extract and heavy whipping cream, then beat until light and fluffy.
  • Spread or pipe the frosting onto the completely cooled cupcakes and decorate with sixlets, sprinkles or nonpareils, if desired.
