Rootbeer Cupcakes
  1. Preheat oven to 350 degrees F. Line 12 muffin cups with paper liners. Set aside.
  2. In a small mixing bowl, whisk to combine the wet ingredients. Set aside.
  3. In a large mixing bowl, whisk together the dry ingredients. Create a well in the center of the dry ingredients, and pour the wet ingredients into the well. Stir to create a smooth batter.
  4. Spoon batter into prepared muffin tin. Bake in preheated oven for 18-20 minutes, or until a toothpick inserted into the middle comes out clean. Remove from oven and allow to stand for 5 minutes before transferring cupcakes to a wire rack. Allow to cool completely before frosting. Store in an airtight container. The flavour increases by the the second day.
Rootbeer Float Buttercream
  1. In a stand mixer fitted with a paddle attachment, beat the butter until fluffy. Add 1 1/2 cups of the confectioners' sugar, salt, vanilla and rootbeer extract. Beat until smooth.
  2. Add the remaining 1 1/2 cups of confectioners' sugar and continue to beat. Add 2 Tbsp of milk or cream, and beat the buttercream until light and fluffy. Add 1 more Tbsp of milk or cream if necessary, to get the consistency that you desire.
  3. Frost cupcakes with a knife or a pastry bag fitted with a large piping tip.

    Thanks for sharing

    Oh man…we JUST got back from our annual weekend across the border. Will have to wait for a whole year to try these! Sounds amazing.

    Can you use root beer , the beverage in place of the extract? Is there any ohter substitution possible?

    • says

      No, using rootbeer will not give you enough of the flavour, the rootbeer extract is very concentrated, a little goes a long way. I’ve also seen Lorann candy flavouring, which could be used in place of the rootbeer concentrate as well. HTH
