What is your perfect holiday moment? Mine is to have both of my children home for the holidays. When you don’t live close by it makes it even more special. This year I am going to be the lucky mom who has both of her children in the same room at the same time for the holidays. I’m so happy that we can all be together again, even if it will be for just a short time. It’s time to celebrate, its time for cupcakes!

Rootbeer Float Cupcake

Why Root Beer Float Cupcakes for the holidays? When I was a young girl I loved Root Beer Floats. I loved the way the root beer would freeze slightly around the vanilla ice cream and I remember loving to eat that part of the float in particular. I also loved chocolate cake. In particular, my Nanny’s Chocolate Mayonnaise Cake. It would always be my birthday request from Nanny or Mom as my birthday cake. This year we will be celebrating not only the holidays, but will be celebrating my youngest son’s birthday which happens to be December 26th! We are a cupcake loving family, so to me, creating the perfect holiday moment combined with memories and treats is what mom needs most.

3-ingredient cake (1 of 1)-2

I decided to give the cupcakes a trial run to see how they would turn out and to see if that Root Beer flavor would come through in the cake (which it did!). I put my cake mix, 2 egg whites, and 1-12 ounce can of A&W TEN® into a mixing bowl.

Using my hand mixer on medium speed, I blended the ingredients together until they were smooth.

I used my large cookie scoop to place the batter in the cupcake liners. If you don’t have a large cookie scoop, you can measure about ¼ cup of batter into each liner. I needed two cupcake tins as recipe was going to yield 24 cupcakes! I baked the cupcakes at 350 for 20 minutes, then set them out to cool.

While they were cooling, I put together the buttercream frosting. I needed some A&W TEN®, confectioner’s sugar, and unsalted butter.

I mixed the frosting ingredients together and frosted the cool cupcakes, then decorated with a maraschino cherry. I always loved to have a cherry on top of my Root Beer Float!

Calories: 148kcal


For the cake:

  • 1-18.25 ounce box of chocolate cake mix
  • 2 egg whites
  • 1 can 12 oz A&W TEN®

For the frosting:

  • 3 cups confectioners sugar
  • 1 tablespoon unsalted butter melted
  • 1/4 cup A&W TEN® more if needed for correct consistency


  • 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.

      I used the Root Beer in the icing. It did not change the color of the icing 🙂

    Can i use a cake mix other than chocolate? May i use a 9×17 glass baking dish instead?

    • Shelby December 10, 2015 at 7:54 pm - Reply

      Hi Alice, yes you can use whatever flavor cake mix you like and if you prefer to make a cake rather than cupcakes a 9×13 would work best. Glass is fine.

  14. […] While I am at Walmart, I always grab some A&W Root Beer. Not only because I love it, but because it will bring back my memories of the days I would go to town with Mom as a young girl! I like to bring those memories home with me and create new ones with my family and friends. And, one of those ways is to incorporate the root beer flavor in my food, like I did with these Caramelized Onions with Root Beer Glaze and Root Beer Float Cupcakes! […]
