Ingredients

Scale

Main Ingredients:

  • 2 ½ cups all-purpose flour
  • 1 ½ cups M&Ms (plus extra for topping)
  • 1 cup brown sugar, packed
  • 1 cup (2 sticks) unsalted butter, melted
  • 2 large eggs

Sweeteners and Flavor Enhancers:

  • ½ cup granulated sugar
  • 1 teaspoon vanilla extract
  • ½ cup chocolate chips (optional)

Leavening and Seasoning:

  • 1 teaspoon baking soda
  • ½ teaspoon salt

Instructions

  1. Prepare the baking environment by heating the oven to 350F (175C) and lining a 9×13-inch pan with parchment paper or applying a light grease coating.
  2. Create a smooth wet mixture by whisking melted butter with brown and granulated sugars until fully integrated, then incorporate eggs and vanilla extract, stirring until the texture becomes uniform and silky.
  3. In a separate vessel, thoroughly combine flour, baking soda, and salt, ensuring even distribution of dry ingredients.
  4. Gradually merge the dry ingredient mixture into the wet ingredients, stirring gently until just combined, avoiding overmixing to maintain a tender texture.
  5. Carefully fold chocolate chips and M&Ms into the cookie dough, distributing them evenly throughout the mixture.
  6. Transfer the dough into the prepared pan, spreading it uniformly and creating an even surface.
  7. Strategically sprinkle additional M&Ms across the top of the dough for enhanced visual appeal and extra chocolate bursts.
  8. Place the pan in the preheated oven and bake for 25-30 minutes, monitoring until the edges develop a golden-brown color and a toothpick inserted into the center emerges clean.
  9. Remove from the oven and allow the cookie bars to cool completely within the pan, which helps them set and achieve the perfect chewy consistency.
  10. Once cooled, slice into rectangular bars and serve, enjoying the rich, chocolatey treat.

Notes

  • Customize M&M colors for seasonal themes or special occasions, matching holiday color schemes for festive presentation.
  • Ensure butter is melted but not hot when mixing with sugars to prevent ingredient separation and maintain smooth texture.
  • Use parchment paper overhang for easy bar removal, allowing clean cuts and effortless serving without damaging the cookie bars.
  • Replace chocolate chips with alternative mix-ins like chopped nuts or dried fruit for dietary variations or personal flavor preferences.
