Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, softened
  • 1 1/2 cups granulated sugar
  • 2 large eggs
  • 1 tablespoon vanilla extract
  • 4 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1/2 cup milk
  • For the Frosting: 4 cups powdered sugar
  • 1/2 cup (1 stick) unsalted butter, softened
  • 1 teaspoon vanilla extract
  • 3–4 tablespoons milk
  • Pinch of salt
  • Sprinkles, for decoration (optional)

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.
  3. Beat in the eggs one at a time, mixing well after each addition. Stir 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 on low speed until just combined. Do not overmix.
  6. Press the dough evenly into the prepared baking pan.
  7. Bake for 20 to 25 minutes, or until the edges are lightly golden and a toothpick inserted near the center comes out with moist crumbs attached.
  8. Let the cookie bars cool completely in the pan on a wire rack.
  9. To make the frosting, beat the softened butter until smooth. Gradually add the powdered sugar, vanilla extract, and salt. Add milk one tablespoon at a time until you reach a smooth, spreadable consistency.
  10. Spread the fluffy vanilla frosting evenly over the cooled cookie bars.
  11. Decorate immediately with sprinkles, if using. Once the frosting sets slightly, use the parchment overhang to lift the bars out and cut them into squares.

Notes

  • For the best melt in your mouth cookie bars texture, ensure your butter and eggs are at room temperature before starting.
  • If you want bakery style cookie bars, chill the dough for 30 minutes before pressing it into the pan.
  • These simple dessert bars freeze well; frost them completely, then cut and place in an airtight container between layers of wax paper.
