Ingredients

Units Scale
  • For the Sugar Cookie Bars:
    • 1 cup (225 g) unsalted butter, softened
    • 1 cup (200 g) granulated sugar
    • 1/2 cup (100 g) powdered sugar
    • 2 large eggs
    • 1 teaspoon vanilla extract
    • 1/2 teaspoon peppermint extract
    • 2 3/4 cups (350 g) all-purpose flour
    • 1 teaspoon baking powder
    • 1/2 teaspoon baking soda
    • 1/4 teaspoon salt
  • For the Peppermint Frosting:
    • 1/2 cup (115 g) unsalted butter, softened
    • 3 cups (375 g) powdered sugar
    • 2 tablespoons heavy cream (or milk)
    • 1/2 teaspoon peppermint extract
    • 12 drops red food coloring (optional, for a festive pink hue)
  • For Garnish:
    • 1/4 cup crushed candy canes or peppermint candies

Instructions

  1. Prepare the Sugar Cookie Bars:
    • Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or grease it well.
    • In a large bowl, cream together the butter, granulated sugar, and powdered sugar until light and fluffy.
    • Beat in the eggs, vanilla extract, and peppermint extract until fully combined.
    • In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
    • Press the dough evenly into the prepared pan.
    • Bake for 18-20 minutes, or until the edges are lightly golden and the center is set. Remove from the oven and let cool completely in the pan.
  2. Make the Peppermint Frosting:
    • In a medium bowl, beat the butter until creamy.
    • Gradually add the powdered sugar, one cup at a time, alternating with the heavy cream. Beat until smooth and fluffy.
    • Mix in the peppermint extract and red food coloring (if using) until evenly combined.
  3. Frost and Garnish the Bars:
    • Spread the peppermint frosting evenly over the cooled sugar cookie bars.
    • Sprinkle the crushed candy canes over the top for a festive touch.
  4. Cut and Serve:
    • Use a sharp knife to cut the bars into squares or rectangles. Serve immediately or store in an airtight container.

Notes

  • For thicker bars, use a smaller pan (e.g., 8×8-inch) and bake for a few extra minutes.
  • If you prefer less sweetness, reduce the powdered sugar in the frosting slightly.
  • These bars can be made up to 3 days in advance and stored in an airtight container at room temperature or refrigerated.
