Description

Indulgent M&M cookie bars blend childhood nostalgia with sweet chocolate happiness in one irresistible dessert. Colorful candy-studded bars deliver chewy comfort that sparks joy for cookie enthusiasts seeking pure deliciousness.


Ingredients

Scale
  • 2 large eggs
  • 1 cup (226 g) unsalted butter, melted
  • 1 cup (200 g) brown sugar, packed
  • ½ cup (100 g) granulated sugar
  • 2 ½ cups (313 g) all-purpose flour
  • 1 ½ cups M&Ms (plus extra for topping)
  • 1 tsp vanilla extract
  • 1 tsp baking soda
  • ½ tsp salt
  • ½ cup (85 g) chocolate chips (optional)

Instructions

  1. Oven Preparation: Warm the oven to 350F (175C) and ready a 9×13-inch baking pan by lining with parchment paper or applying a light grease coating.
  2. Wet Ingredient Fusion: In a spacious mixing bowl, vigorously whisk melted butter with brown and granulated sugars until achieving a silky consistency. Incorporate eggs and vanilla extract, blending thoroughly until uniform.
  3. Dry Ingredient Integration: Separately combine flour, baking soda, and salt through a gentle whisking motion. Gradually fold the dry mixture into the wet ingredients, stirring minimally to prevent overmixing.
  4. Confectionery Incorporation: Delicately fold M&Ms and chocolate chips into the developing dough, ensuring even distribution throughout the mixture.
  5. Baking & Decorative Finishing: Transfer the dough into the prepared pan, spreading evenly and garnishing the surface with additional M&Ms for visual appeal. Slide the pan into the preheated oven, baking for 25-30 minutes until the edges transform to a golden hue and a inserted toothpick emerges clean.
  6. Cooling & Serving: Allow the cookie bars to cool completely before slicing into delectable squares, ready to be savored and shared.

Notes

  • Use melted butter at room temperature for smoother mixing and better texture in cookie bars.
  • Stir dry ingredients into wet ingredients just until combined to prevent tough, dense bars.
  • Reserve some M&Ms to press on top of the batter before baking for a more vibrant, picture-perfect finish.
  • Check bars at 25 minutes and remove from oven when edges are golden but center still looks slightly soft to ensure chewy, moist texture.
