Ingredients

Scale

Dry Ingredients:

  • 2.25 cups all-purpose flour
  • 0.5 teaspoon baking soda
  • 0.5 teaspoon salt

Sugars and Sweeteners:

  • 1 cup packed brown sugar (light or dark)
  • 0.5 cup granulated sugar

Wet Ingredients and Mix-ins:

  • 1 cup unsalted butter, melted and slightly cooled
  • 2 large eggs, at room temperature
  • 2 teaspoons vanilla extract
  • 1.5 cups M&M candies
  • 1 cup semi-sweet chocolate chips

Instructions

  1. Prepare a 9×13 inch baking pan by lining with parchment paper, ensuring overhang for easy removal. Preheat oven to 350°F.
  2. Using an electric mixer, whip butter and sugars until light and airy, creating a creamy texture that incorporates air for a softer cookie bar.
  3. Incorporate eggs and vanilla extract into the butter mixture, blending until smooth and uniform in consistency.
  4. Gently fold dry ingredients – flour, baking soda, and salt – into the wet mixture, stirring until just combined to prevent overmixing.
  5. Delicately distribute most of the M&Ms throughout the dough, reserving some for topping to create a visually appealing surface.
  6. Transfer the dough to the prepared pan, using a spatula to spread evenly and create a level surface. Sprinkle remaining M&Ms on top for extra color and crunch.
  7. Bake in the preheated oven for 22-27 minutes, watching for golden edges and a slightly set center. Avoid overbaking to maintain a soft, chewy texture.
  8. Remove from oven and allow to cool completely in the pan for at least 1 hour. Use parchment paper edges to lift and transfer to a cutting board.
  9. Slice into uniform bars, creating approximately 16-20 servings depending on desired size.

Notes

  • Customize your M&M colors to match seasonal themes or special occasions for a festive touch.
  • Slightly underbake the bars for a gooier, softer texture that melts in your mouth.
  • Chill the dough for 30 minutes before baking to prevent excessive spreading and create a thicker bar.
  • Swap out regular M&Ms for peanut, pretzel, or dark chocolate varieties to add unique flavor variations.
