Ingredients
- 3/4 cup sugar
- 1/2 cup unsalted butter, softened to room temperature (for cookie base)
- 1 tsp vanilla extract
- 1 egg
- 1 3/4 cups flour
- 1 tsp baking powder
- 1/4 tsp salt
- 1/2 cup crushed peppermints
- 2 cups powdered sugar
- 1/2 cup unsalted butter, softened to room temperature (for frosting)
- 1 tsp peppermint extract
- 1 tsp vanilla extract (for frosting)
- 2 tbsp milk
- 1/4 cup crushed peppermints (for topping)
Instructions
- Step 1: Line a 9×9-inch baking dish with parchment paper, leaving ends hanging over the sides for easy removal. Spray the parchment with non-stick cooking spray. Preheat your oven to 350°F.
- Step 2: In a large bowl, beat 3/4 cup sugar and 1/2 cup softened butter with a hand mixer until light and fluffy. Add 1 tsp vanilla extract and 1 egg, then beat until fully combined.
- Step 3: Add 1 tsp baking powder, 1/4 tsp salt, and half of the flour (about 7/8 cup) to the butter mixture. Mix to combine, then add the remaining flour and continue mixing until the batter forms.
- Step 4: Stir in 1/2 cup crushed peppermints. Pour the batter into the prepared baking dish, scraping down the sides to transfer all batter.
- Step 5: Evenly spread the batter in the dish using a spatula or your hands. If thick, press it out gently with your hands. Bake for 20-25 minutes until golden and a toothpick comes out clean. Let cool completely in the dish.
- Step 6: For the frosting, combine 2 cups powdered sugar, 1/2 cup softened butter, 1 tsp peppermint extract, 1 tsp vanilla extract, and 2 tbsp milk in a medium bowl. Beat until smooth and fluffy.
- Step 7: Lift the cooled bars out of the dish using the parchment paper. Spread the frosting evenly over the top.
- Step 8: Sprinkle 1/4 cup crushed peppermints over the frosting. Chill the bars in the fridge for about 10 minutes to firm up the frosting.
- Step 9: Slice into squares and serve. Enjoy the festive flavor in every bite!
Tips & Variations
- For a stronger peppermint flavor, add an extra 1/2 tsp of peppermint extract to the frosting.
- Use crushed candy canes instead of peppermints for a different texture and flavor.
- To make cleanup easier, let the bars cool completely before lifting out with parchment paper.
- If you prefer a thinner frosting, add a little more milk, one teaspoon at a time, until desired consistency is reached.
Storage
Store the Peppermint Sugar Cookie Bars in an airtight container in the refrigerator for up to 5 days. Let the bars come to room temperature before serving, or enjoy chilled for a firmer texture. They can also be frozen for up to 2 months; thaw in the fridge before serving.
