Step-by-Step Instructions for M&M'S Cookie Bars
  1. Preheat your oven to 350°F (175°C) and prepare a 9x13 aluminum baking pan by lining it with foil.
  2. In a stand mixer, combine 1 cup of unsalted butter, 1 cup of granulated sugar, and 1 cup of golden brown sugar. Beat until fluffy.
  3. Mix in 2 large eggs and 2 teaspoons of pure vanilla extract until smooth.
  4. Gradually add 2.5 cups of all-purpose flour, 1 teaspoon of baking soda, and 0.5 teaspoon of salt, mixing until just combined.
  5. Fold in 1 cup of Halloween M&M's and 0.5 cup of mini chocolate chips, reserving some for topping.
  6. Spread the dough evenly in the prepared pan and press reserved M&M's and chocolate chips on top.
  7. Bake for 30-35 minutes, until a toothpick comes out clean or with a few moist crumbs.
  8. Allow the cookie bars to cool completely in the pan, then lift out with foil and slice into squares.
