Method
 

Cookie Bars
  1. Preheat oven to 350°F (175°C) and grease a 9x13 inch baking pan.
  2. In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
  3. Beat in the egg and vanilla extract until well combined.
  4. In a separate bowl, whisk together the flour, baking powder, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined and a soft dough forms.
  6. Press the dough evenly into the prepared baking pan.
  7. Bake for 10-14 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out clean; do not overbake.
  8. Let the cookie bars cool completely in the pan on a wire rack before frosting.
Vanilla Buttercream Frosting
  1. In a medium bowl, cream the softened butter until smooth.
  2. Gradually add the powdered sugar, alternating with milk or cream, mixing until smooth and creamy.
  3. Stir in the vanilla extract and food coloring if desired.
  4. Once the cookie bars are completely cool, spread the frosting evenly over the top.
  5. Cut into bars and decorate with sprinkles or candies before serving.

Notes

For best results, ensure your butter and egg are at room temperature. You can decorate these bars with festive sprinkles, candies, or edible glitter to enhance the Christmas theme. Store leftovers in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.
