  • 1/2 cup unsalted butter, softened
  • 1/2 cup packed brown sugar
  • 1/2 cup granulated sugar
  • 1 large egg
  • 2 teaspoons vanilla extract
  • 2 1/2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup colored sprinkles (jimmies)

For the Frosting:

  • 1/2 cup unsalted butter, softened
  • 2 teaspoons vanilla extract
  • 1/4 teaspoon salt
  • 3 1/2 cups powdered sugar
  • 1/4 cup heavy cream
  • More sprinkles for topping


  1. Prepare the Cookie Base:
    • Preheat the oven to 375°F (190°C). Spray a 9×13 inch baking pan with non-stick baking spray.
    • In a large bowl, cream together the butter, brown sugar, and granulated sugar until creamy.
    • Mix in the egg and vanilla extract.
    • Gradually add flour, baking powder, and salt, mixing until just combined.
    • Fold in the colored sprinkles and press the dough evenly into the prepared pan.
    • Bake for 14-15 minutes or until the edges are just set. Allow to cool completely in the pan.
  2. Make the Frosting:
    • In a mixing bowl, cream together the butter, vanilla extract, and salt.
    • Gradually add the powdered sugar, alternating with heavy cream, beating until the frosting is light and fluffy.
  3. Assemble the Bars:
    • Spread the frosting evenly over the cooled cookie base.
    • Sprinkle additional colored sprinkles on top for decoration.
    • Cut into bars and serve.


  • Creaming Butter and Sugar: Ensure that the butter is properly softened for easier creaming with the sugars, which helps create a light and fluffy texture in the cookie base.
  • Even Spreading: Use a spatula or the back of a spoon to evenly press the cookie dough into the pan, which helps achieve a uniform thickness and even baking.
  • Decorative Flair: Get creative with the sprinkles on top of the frosting for a more festive look, matching the color theme of your event or celebration.


  • Store the cookie bars in an airtight container at room temperature to maintain their softness and freshness. They can typically be kept for up to 5 days.
