Ingredients

  • 1 cup Butter (1/2 cup melted in saucepan, 1/2 cup mixed with sugars)
  • 1 cup Brown Sugar
  • 3/4 cup Sugar
  • 1 large Egg
  • 1 large Egg Yolk
  • 1 teaspoon Vanilla
  • 2 1/3 cups Flour
  • 1 teaspoon Baking Soda
  • 1 teaspoon Salt
  • 1 1/2 cups Chocolate Chips
  • 2 cups M & M's

Instructions

  1. Preheat oven to 350 degrees. Melt 1/2 cup of butter (1 stick) in a saucepan over medium-low heat. Let it completely melt and start to bubble. Remove from heat.

  2. In a large mixing bowl, combine the remaining 1/2 cup of butter (1 stick), brown sugar, and sugar. Using a stand mixer or handheld mixer, mix for 2 minutes or until light and fluffy. Carefully add the melted butter and continue to mix for 3 minutes longer.

  3. Add egg, egg yolk, and vanilla and mix for 1 minute.

  4. Fold in flour, baking soda, and salt. Add chocolate chips and M & M's.

  5. Place a piece of parchment paper in a 9 x 13 pan. Press around the sides. Spread cookie dough into baking pan. Bake for 22-25 minutes. Remove from the oven and let set up for at least 15 minutes before cutting into bars.
