  • 2 1/4 cups all purpose flour
  • 1 tsp baking soda
  • 3/4 tsp salt
  • 3/4 cup unsalted butter melted
  • 3/4 cup brown sugar
  • 3/4 cup granulated sugar
  • 2 eggs
  • 1/2 tsp vanilla extract
  • 1 cup chocolate chips or M&M's
  • leftover Halloween candy roughly chopped (choclated based works best, no gummies)


  • Preheat your oven to 350 degrees F.
  • Line a baking dish with parchment pray or spray with nonstick baking spray.
  • In a medium bowl, mix together flour, baking soda and salt.
  • In a separate bowl (I used my Kithchen Aid) mix together butter, brown sugar and granulated sugar until creamed together.
  • Add in the eggs and vanilla to the butter sugar mixture, mixing well.
  • Add the dry ingredients (flour mixture) into the wet ingredients, and stir until combined.
  • Sprinkle in the chocolate chips or M &Ms
  • Spread the cookie dough into the prepared baking dish, pressing down until firm.
  • Bake until golden brown (about 20-25 minutes).
  • While the cookie dough bakes, unwrap your Halloween candies and chop or break into chunks.
  • When the cookie dough is done baking, remove from oven. Press the chocolate pieces into the top of the cookie while still warm. We had leftover googly eye sprinkles so I sprinkled those on as well.
  • Allow to completely cool, then cut and serve.
