Ingredients
  

Group: Cookie Base
  • 3 cups all-purpose flour
  • 1 tsp. baking soda
  • 1 tsp. baking powder
  • ½ tsp. salt
  • 1 cup unsalted butter, softened To room temperature
  • 1 ½ cups granulated sugar
  • 1 large egg
  • 1 tsp. vanilla extract
  • 1 tsp. peppermint extract
Group: Frosting
  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar
  • 1 tsp. vanilla extract
  • 1 tsp. peppermint extract
  • 2-3 Tbsp. heavy cream To desired consistency
  • candy cane pieces For topping (optional)

Equipment

  • 9x13-inch baking dish Lined with parchment paper
  • Medium bowl
  • Large mixing bowl
  • Wire rack For cooling

Method
 

  1. Preheat your oven to 350°F (175°C). Line a 9x13-inch baking dish with parchment paper.
  2. In a medium bowl, whisk together flour, baking soda, baking powder, and salt.
  3. In a large mixing bowl, beat the softened butter and sugar until light and fluffy.
  4. Add egg, vanilla extract, and peppermint extract. Mix until fully combined.
  5. Gradually add the dry ingredients into the wet mixture and mix until just combined.
  6. Transfer the dough into the prepared baking dish and press evenly into the corners. Bake for 20-25 minutes until lightly golden.
  7. Cool completely on a wire rack before frosting.
  8. For the frosting, beat the softened butter with powdered sugar, vanilla extract, peppermint extract, and enough heavy cream until smooth.
  9. Frost the cooled cookie bars evenly and sprinkle with crushed candy cane pieces.
  10. Lift the bars out using the parchment overhang and slice into squares for serving.

Notes

Allowing the cookie bars to cool completely before frosting will prevent the frosting from melting.
