Ingredients

• Cake
• 1 box white cake mix, 15.25 oz
• 1 cup sugar
• 1 cup all purpose flour
• 3/4 tsp salt
• 4 egg whites
• 1 cup milk
• 1/2 cup buttermilk
• 1 cup sour cream
• Vanilla Buttercream
• 2 sticks butter, room temperature
• 1/2 cup vegetable shortening (can be replaced with butter)
• 1 tsp vanilla extract
• 3-4 cups powdered sugar

Preparation

Step 1

Preheat the oven to 350º F.

In a large mixing bowl combine the cake mix, sugar, flour, salt, egg whites, milk, buttermilk, and sour cream, beat with an electric mixer until combined, 2-3 minutes.

Spray a 9x13 inch pan with non-stick cooking spray. Pour the batter into the pan and bake for 37-43 minutes or until a toothpick inserted in the center of the cake comes out clean. Allow the cake to cool completely before adding frosting.

Vanilla Buttercream

In a mixing bowl, combine the butter, vegetable shortening and vanilla extract, beat using an electric mixer until fluffy. Begin to add the powdered sugar, about 1 cup at a time, mixing by hand. Continue adding powdered sugar until the frosting no longer looks wet and tastes good to you.

Then I use my electric mixer one last time to make sure the powdered sugar is really incorporated and ready to go. If the frosting becomes too thick, add a dash of milk or heavy cream.

Spread on top of the cooled cake, add sprinkles if desired.
