Ingredients

For the cookie:

  • Cooking spray
  • 2 1/2 c. all-purpose flour, spooned and leveled
  • 1 tsp. cornstarch
  • 1/2 tsp. baking powder
  • 1/2 tsp. kosher salt
  • 3/4 c. (1 1/2 sticks) unsalted butter, at room temperature
  • 1 1/2 c. granulated sugar
  • 2 large eggs
  • 1 tsp. pure vanilla extract
For the buttercream:

1/2 c. (1 stick) unsalted butter, at room temperature

Holiday sprinkles

1 Tbsp. whole milk

1 tsp. pure peppermint or vanilla extract

2 c. confectioners’ sugar

Directions

  1. Step 1: Make the cookie bars: Preheat oven to 350°F. Lightly grease a 9- by 9-inch baking pan and line with parchment paper, leaving a 2-inch overhand on two sides. Whisk together flour, cornstarch, baking powder, and salt in a bowl. 
  2. Step 2: Beat butter and sugar with an electric mixer on medium speed until light and fluffy, 1 to 2 minutes. Add eggs and vanilla and beat until well combined. Slowly beat in flour mixture until combined. 
  3. Step 3: Transfer dough to prepared baking pan and spread evenly. Bake until edges are golden brown, 25 to 30 minutes. Cool in pan on a wire rack, 15 minutes. Use the parchment paper to lift cookie out of the pan and cool completely on wire rack. 
  4. Step 4: Make the buttercream: Beat butter with an electric mixer on medium speed until light and creamy, 1 to 2 minutes. Beat in milk, peppermint or vanilla extract, and confectioners’ sugar. Spread frosting over cookie bars and sprinkle with holiday sprinkles. Cut into squares.
