Equipment

  • 9x9 baking dish
  • Electric mixer or hand mixer
  • Mixing bowls
  • Parchment paper or non-stick spray
  • Spatula or offset spatula
  • Measuring Cups and Spoons

Ingredients
  

  • 3/4 cup of sugar
  • 1/2 cup of unsalted butter softened to room temp
  • 1 tsp vanilla extract
  • 1 egg
  • 1 3/4 cup of flour
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 1/2 cup of crushed peppermints
  • 2 cups powdered sugar
  • 1/2 cup of unsalted butter softened to room temp
  • 1 tsp peppermint extract
  • 1 tsp vanilla extract
  • 2 tbsp milk
  • 1/4 cup of crushed peppermints

Instructions
 

  • Line a 9x9-inch baking dish with parchment paper, allowing the ends to hang over the sides. This will help you lift the bars out later. Spray the parchment with non-stick cooking spray. Preheat the oven to 350°F.
  • In a large mixing bowl, combine 3/4 cup of sugar and 1/2 cup of softened butter. Use a hand mixer to beat them together until light and fluffy. Add 1 tsp vanilla extract and 1 egg, and beat again until fully incorporated.
  • To the butter mixture, add 1 tsp baking powder, 1/4 tsp salt, and half of the 1 3/4 cups flour. Beat to combine. Then, add the remaining flour and continue mixing until a batter forms.
  • Stir in 1/2 cup of crushed peppermints. Pour the batter into the prepared baking dish, scraping down the sides of the bowl to ensure all the batter is transferred.
  • Use a spatula or your hands to evenly spread the batter in the dish. If the batter is thick, lightly press it out with your hands. Bake the batter for 20-25 minutes, or until the top is golden and a toothpick inserted comes out clean. Let the bars cool completely in the baking dish.
  • In a medium mixing bowl, combine 2 cups powdered sugar, 1/2 cup softened butter, 1 tsp peppermint extract, 1 tsp vanilla extract, and 2 tbsp milk. Beat with a hand mixer until smooth and fluffy.
  • Once the cookie bars have cooled, lift them out of the baking dish using the parchment paper. Spread the frosting evenly over the top.
  • Sprinkle 1/4 cup of crushed peppermints over the frosting. Place the bars in the fridge for about 10 minutes to let the frosting firm up.
  • Once the frosting has set, slice the bars into squares. Serve and enjoy the holiday spirit in every bite!

Notes

Tips and Tricks!

  • Keep the bars fresh by storing them in an airtight container in the fridge for 3-4 days.
  • No peppermints? Swap them for candy canes!
  • Out of parchment paper? Use foil as a substitute.
  • Let the bars cool completely before frosting to prevent the frosting from melting.
