¼cupA&W TEN®more if needed for correct consistency
Instructions
Preheat oven to 350 degrees F. Line two cupcake tins with paper liners.
In a large mixing bowl, combine cake mix, egg whites, and A&W TEN® until batter is smooth.
Scoop about ¼ cup of batter into each cupcake liner. Bake at 350 for about 20 minutes, or until cake bounces back when lightly touched with the tip of your finger.
Remove from oven and let cool.
To make the frosting, mix together 1 cup of powdered sugar and butter. Add remaining sugar and A&W TEN® and stir until combined.
Add more Root Beer or confectioners sugar as needed to get desired frosting consistency. Be sure the frosting is not too soft. You want it to be easy to pipe or spread, but not so soft it will be runny.
