Ingredients

Scale
  • 1 cup unsalted butter, softened
  • 1 1/2 cups granulated sugar
  • 2 large eggs
  • 1 tablespoon vanilla extract
  • 3 3/4 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup milk
  • For the Frosting:
  • 1/2 cup unsalted butter, softened
  • 3 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 2-4 tablespoons milk
  • Optional: Sprinkles for decoration

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
  2. In a large bowl, cream together the softened butter and granulated sugar until light and fluffy. This step builds the texture.
  3. Beat in the eggs one at a time, then mix in the vanilla extract.
  4. In a separate bowl, whisk together the flour, baking powder, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, alternating with the milk, mixing until just combined. Do not overmix the dough.
  6. Press the dough evenly into the prepared 9×13 inch pan.
  7. Bake for 20 to 25 minutes, or until the edges are lightly golden and the center is set. You want them slightly underdone for a soft texture.
  8. Let the bars cool completely in the pan on a wire rack. This is important before frosting.
  9. To make the frosting, beat the softened butter until smooth. Gradually add the powdered sugar, vanilla extract, and milk, one tablespoon at a time, until you reach a smooth, spreadable consistency.
  10. Spread the frosting evenly over the cooled cookie bars. Add sprinkles immediately if using.
  11. Once the frosting is set, use the parchment paper overhang to lift the bars from the pan. Cut into squares.

Notes

  • For the chewiest bars, slightly underbake them; they will firm up as they cool.
  • You can easily adapt the frosting color or sprinkles for any holiday or celebration.
  • These are excellent make ahead dessert bars; store them covered at room temperature for up to three days.
