Sweet chocolate m&m cookie bars bring layers of nostalgic comfort to classic dessert expectations. Homemade chocolate chip base studded with colorful candies creates irresistible treats you’ll savor with childhood memories.


Ingredients

Scale

Dry Ingredients:

  • 2 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt

Wet Ingredients:

  • 1 cup butter, melted
  • 2 large eggs
  • 2 teaspoons vanilla extract

Sweet Ingredients:

  • 1 cup brown sugar
  • 1/2 cup granulated sugar
  • 1 1/2 cups M&Ms

Instructions

  1. Warm the oven to 350F and coat a 9×13-inch baking pan with non-stick spray.
  2. Combine melted butter with brown and granulated sugars in a mixing bowl, stirring until completely smooth and uniform.
  3. Incorporate eggs and vanilla extract, whisking thoroughly until the mixture becomes light and fluffy.
  4. Separately sift together flour, baking soda, and salt to ensure even distribution of dry ingredients.
  5. Gently fold the dry ingredient mixture into the wet ingredients, stirring carefully to prevent overmixing.
  6. Delicately blend most of the M&Ms into the cookie dough, saving a handful for decorative topping.
  7. Transfer the dough into the prepared baking pan, using a spatula to spread evenly and create a smooth surface.
  8. Strategically place the reserved M&Ms across the top of the dough, pressing them slightly into the surface.
  9. Slide the pan into the preheated oven and bake for 25-30 minutes until edges turn golden brown and center appears set.
  10. Remove from oven and allow to cool completely on a wire rack before slicing into rectangular bars.

Notes

  • Enhance chewiness by slightly underbaking the bars, removing them from the oven when edges are golden but center looks slightly soft.
  • Experiment with different chocolate candies like Reese’s Pieces or chocolate chips for unique flavor variations.
  • For gluten-free option, substitute all-purpose flour with a 1:1 gluten-free baking blend to maintain similar texture and taste.
  • Chill the dough for 30 minutes before baking to prevent excessive spreading and create thicker, more dense cookie bars.
