Now you can have your brownie a la mode and root beer float all at once with these easy root beer float brownie cupcakes by doctoring up boxed brownie mix.

  • Yields: 1-1/2 Dozen


Preheat oven to 350°F. Line two muffin pans with cupcake liners and set aside.

In a large bowl, mix brownie mix and root beer together with a spoon until blended. Pour into lined cups about 3/4 full. Bake for 30 minutes or until tops spring back when lightly touched. Allow to cool completely on a wire rack before frosting.

While the cupcakes are cooling, make the frosting. In a medium bowl, cream butter and shortening together until smooth. Add softened ice cream and mix until combined.

Slowly add in powdered sugar until incorporated. Turn mixer up to medium and beat for 30 seconds. If necessary, add more ice cream or powdered sugar until desired consistency is reached.

Frost cupcakes and decorate, if desired, with hot fudge sauce, sprinkles, and colorful straws.
