Ingredients

  • 3 cups all purpose flour
  • 2 teaspoons baking soda
  • 1 teaspoon salt
  • 1 cup butter, softened
  • 1 3/4 cups sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 2 cups chocolate chips
  • 2 cups M&Ms candy
  • 1/4 cup Christmas-themed candy sprinkles

Instructions

  • Preheat the oven to 350 degrees. Line a baking sheet with parchment paper and lightly coat with non-stick cooking spray. Set aside.
  • In large bowl, use a hand-held mixer to beat together the butter and sugar for 3 minutes.
  • Add the eggs and vanilla and beat for 2 minutes.
  • Add the flour, baking soda and salt. Beat until just combined.
  • Add 1 cup of the chocolate chips and 1 cup of the M&Ms. Stir into the cookie batter using a wooden spoon.
  • Spread the cookie dough as evenly as possible onto the parchment-lined baking sheet. Don't get too worried about the dough being even. It will expand and fill in the gaps during the baking process.
  • Bake for 15 minutes. Remove from oven. Sprinkle over the remaining chocolate chips and M&Ms, along with the candy sprinkles. Return to over and bake for 5 more minutes.
  • Remove from oven. Allow to cool, undisturbed, for 15 minutes. Carefully slide the giant cookie off of the sheet pan and onto a cooling rack to continue cooling.
  • Once completely cooled, slice into large bars.

Notes

Sheet Pan: I am using a two thirds sheet pan (also referred to as a three quarter size sheet pan) and measures 21" by 15".
