Ingredients

Scale

Dry Ingredients

  • 3 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon salt

Wet Ingredients

  • 1 cup unsalted butter (room temperature)
  • 1 cup light brown sugar (packed)
  • ½ cup granulated sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract

Add-ins

  • 1 ⅓ cup M&M candies (divided)
  • 1 cup semi-sweet chocolate chips

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 350℉. Line a 9×13-inch baking pan with parchment paper or foil to ensure easy removal after baking.
  2. Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, baking soda, and salt. This ensures even distribution of leavening agents.
  3. Cream Butter and Sugars: Using a stand mixer or hand mixer, beat the room temperature unsalted butter with the brown sugar and granulated sugar until the mixture is light, fluffy, and well combined.
  4. Add Eggs and Vanilla: Beat in the eggs, one at a time, along with the vanilla extract until the dough is smooth and fully incorporated.
  5. Combine Dry and Wet Ingredients: On low mixer speed, gradually add the dry flour mixture to the wet ingredients, mixing just until combined to avoid overworking the dough.
  6. Fold in Mix-ins: Gently fold in one cup of M&M candies and all the semi-sweet chocolate chips to the cookie dough.
  7. Press Dough into Pan: Spread the cookie dough evenly in the prepared baking pan, pressing down gently to form an even layer. Sprinkle the remaining ⅓ cup of M&M candies evenly on top for a colorful finish.
  8. Bake: Bake in the preheated oven for 22 to 30 minutes, until the top is golden, edges are lightly browned, and the center is just set but still slightly soft.
  9. Cool and Serve: Remove the pan from the oven and place on a cooling rack. Allow the cookie bars to cool completely before slicing into squares and serving to ensure clean cuts.

Notes

  • Room temperature butter helps achieve a smoother and more consistent dough texture.
  • Pressing the dough evenly into the pan ensures uniform baking and thickness.
  • Cooling the bars completely before slicing helps prevent them from crumbling.
  • You can substitute M&Ms with any other colorful candy-coated chocolates or skip the chocolate chips for a different texture.
