Ingredients

  • 12 Tablespoons (1 & 1/2 sticks) unsalted butter, softened
  • 1 cup brown sugar
  • 1/2 cup granulated white sugar
  • 1 large egg
  • 1 large egg yolk
  • 1 Tablespoon vanilla extract
  • 1 teaspoon baking soda
  • 2 teaspoons cornstarch
  • 1/4 teaspoon salt
  • 2 cups all-purpose flour
  • 2/3 cup semi-sweet chocolate chips
  • 3/4 cup Valentine's M&M's candies plus more for garnish
  • 1/4 cup Valentine's heart sprinkles

Instructions

  • Preheat oven to 350 degrees F. Line a 9x13 rectangular baking pan with foil, extending the sides of the foil over the edges of the pan. Spray the foil liberally with cooking spray; set aside.
  • In the bowl of a stand mixer, cream together the butter, brown sugar and white sugar with the paddle attachment until creamy and pale yellow, about 1 minute. Add in the egg, followed by the egg yolk and vanilla, beating well after each addition. Lastly, add in the baking soda, cornstarch, salt and flour and mix on low speed until incorporated. Stir in the chocolate chips, M&M's and sprinkles by hand until combined.
  • Press the dough evenly into the prepared baking sheet. If desired, press in some more Valentine's M&M's into the top of the dough so they are more visible.
  • Bake for 25-30 minutes or until the cookie bars are light golden brown and a toothpick inserted near the center comes out clean. Cool completely before cutting into bars.
