Ingredients

**For the Cookie Bars:**

  • ¾ cup salted butter melted
  • 1 cup light brown sugar
  • ⅓ cup granulated sugar
  • 1 tbsp vanilla extract
  • 2 eggs room temperature
  • 2 cups all-purpose flour
  • 1 tbsp cornstarch
  • ½ tsp baking soda
  • ½ tsp salt

**For the Frosting:**

  • ¾ cup salted butter room temperature
  • 4 cups powdered sugar
  • 1 tsp vanilla extract
  • 3-5 tbsp heavy cream or milk room temperature
  • ½ tsp salt

Instructions

**For the Cookie Bars:**

  • Preheat the oven to 350°F. Grease a metal 9×13 pan and set aside.
  • In a stand mixer, combine melted butter, brown sugar, and granulated sugar. Mix until combined. Add vanilla and eggs, and mix until incorporated.
  • On low speed, add flour, salt, cornstarch, and baking soda. Mix until just combined. Fold in M&Ms, chocolate chips, and sprinkles.
  • Spread batter evenly in the prepared pan. Bake for 22-25 minutes, or until the edges are golden brown. Remove from the oven and cool completely before frosting.

**For the Frosting:**

  • In a stand mixer, beat together butter and powdered sugar for 2-3 minutes until combined. Add vanilla, salt, and 2 tablespoons of heavy cream, and beat until smooth. Adjust the consistency with more heavy cream as needed.
  • Divide frosting into 3 bowls. Add a few drops of red food coloring to one bowl, blue to another, and leave the third white.
  • Pipe alternating colors around the edges using a piping bag with a large tip (like Wilton #8B). Top with additional sprinkles.
  • Slice and serve!
