Equipment

  • 1 9x13-inch baking dish greased and lined with parchment paper
  • 1 electric mixer
  • 1 Mixing Bowl large

Ingredients
  

Sugar Cookie Dough

  • 1 cup unsalted butter softened
  • 1 1/2 cups granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 3 cups all-purpose flour
  • 1 tsp baking powder
  • 1/2 tsp salt

Creamy Icing

  • 1/2 cup unsalted butter softened
  • 4 cups powdered sugar
  • 2 tbsp milk
  • 1 tsp vanilla extract
  • Red and blue gel food coloring

Toppings

  • Red white, and blue sprinkles

Instructions
 

Preparation

  • Preheat your oven to 350°F. Grease a 9x13-inch baking dish and line with parchment paper for easy removal.
  • In a large mixing bowl, cream together the butter and granulated sugar until light and fluffy. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
  • In a separate bowl, whisk together flour, baking powder, and salt. Gradually add to the wet ingredients, mixing until fully combined.
  • Spread the dough evenly in the prepared baking dish. Bake for 20-25 minutes or until the edges are lightly golden. Allow the cookie base to cool completely in the pan on a wire rack.

Icing and Decoration

  • In a clean bowl, beat the softened butter until creamy. Gradually add powdered sugar, milk, and vanilla extract. Beat until smooth and creamy. Divide into three bowls; color one red, one blue, and leave one white.
  • Once the cookie base is cooled, spread the icing over the top in sections or create a marbled effect by swirling the colors together. Decorate with sprinkles immediately to ensure they stick.

Serving and Storage

  • Cut the cookie bars into 16 squares and serve on a platter. They make a perfect addition to any dessert table, especially during patriotic holidays.
  • Store the frosted bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. For longer storage, freeze wrapped in foil for up to 2 months.
