Ingredients

Root Beer Cookie

  • 1 1/2 cups salted butter softened
  • 1 1/2 cups granulated sugar
  • 3 eggs
  • 2 1/2 tsp root beer flavoring I use Lorann's brand
  • 2 tbsp canola oil
  • 4 1/2 cups all purpose flour
  • 3 tsp baking powder

Marshmallow Frosting

  • 1/2 cup butter
  • 3 cups powdered sugar
  • 7 oz marshmallow creme
  • milk as needed for consistency

Instructions

  • Preheat the oven to 350°.
  • In the bowl of a stand mixer cream together the butter and sugar until light and fluffy.
  • Scrape the sides of the bowl and add the eggs, root beer flavoring and oil.
  • Mix until combined.Lastly, add in the flour and baking powder. Mix until the dough forms. The dough will be soft.
  • Scoop your dough out into generous 1/3 cup portions. Roll the cookie dough into a ball and then flatten the cookie dough slightly. Repeat with the remaining dough, arrange on pan.
  • Bake at 350° for 11-14 minutes. The cookies will spread slightly and the centers will puff up when they are ready to be taken out of the oven. Allow the cookies to cool on the pan.
  • Make the frosting, by whipping the butter until smooth.
  • Add the powdered sugar, one cup at a time, adding a little bit of milk after each cup of powdered sugar to keep the consistency like a thick frosting.
  • Add the marshmallow creme to the frosting and mix until well combined.
  • Divide the frosting among the cookies and spread to cover the top of the cookie.
  • Serve chilled.
