Ingredients
  

  • 2 cups all purpose flour
  • 2 teaspoons corn starch
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup unsalted butter, melted
  • 1 cup sugar
  • 1 egg
  • 1 teaspoon pure vanilla extract
  • 1/3 cup rainbow sprinkles (an additional tablespoon for sprinkling on top if desired)

Instructions
 

  • Preheat oven to 350°F and line 8x8 baking pan with parchment paper.
  • In a medium mixing bowl, whisk together flour, corn starch, baking soda, and salt.
  • In a large mixing bowl, stir together butter, sugar, and vanilla.
  • Mix egg into wet ingredients. (If butter is still quite warm from melting, be sure to mix egg in rapidly so that it doesn't become a scrambled egg in the batter.)
  • Gradually stir dry ingredients into wet ingredients until almost completely blended together.
  • Add 1/3 cup sprinkles to cookie dough and mix until evenly distributed. Dry ingredients should also now be fully incorporated.
  • Press dough into prepared pan. Add remaining tablespoon of sprinkles on top if you choose using (no need to press these into the dough).
  • Bake 30 minutes or until slightly golden on top and a test toothpick comes out clean.
  • Let cool completely before cutting into 16 squares.
