A Simple Root Beer Cupcake Recipe. This recipe has the perfect amount of root beer flavor for them. Made from a doctored up cake mix.



Root Beer Cupcakes

  • 1 box of White Cake Mix (I used Pillsbury Classic White Cake Mix)
  • 1 cup of Root Beer (substitute for the water)
  • 3 Eggs (or per your cake mix directions)
  • 1/3 cup of Oil (or per your cake mix directions)

Root Beer Buttercream Frosting

  • 1 cup (2 sticks) unsalted butter, softened
  • 34 cups of powdered sugar, Sifted
  • 1/4 teaspoon salt
  • 1 tablespoon root beer concentrate
  • up to 4 tablespoons milk
  • Food Coloring Gel – optional


Root Beer Cupcakes

  1. Prepare the White Cake Mix per the instructions on the box EXCEPT substitute Root Beer for the water.
  2. Line Cupcake pan with liners
  3. Fill the cupcake liners 1/2 to 2/3rds full
  4. Bake at 350 for 20 min (or per your cake mix instructions)

Root Beer Buttercream Frosting

  1. Beat the butter for a few minutes using your mixer on medium speed.
  2. Add 3 cups of powdered sugar and mix on low speed until blended.
  3. Add the root beer concentrate, salt, and 2 tablespoons of milk. Mix on medium speed for 3 minutes.
  4. If you need stiffer frosting, add the remaining sugar.
  5. If you need a thinner frosting, add the remaining milk.
  6. Add your food coloring gel until you get the color desired. (optional)


I added a touch of brown coloring gel to my icing to give it a bit of a cream color. Seems appropriate since it is root beer flavor.
