Description

These chewy, colorful cookie bars are a nostalgic treat that combines the classic taste of M&M’s with the convenience of a bar format. Perfect for parties, lunchboxes, or a sweet snack anytime!


Ingredients

  • 1 ¾ cups all-purpose flour

  • 1 teaspoon baking soda

  • ½ teaspoon salt

  • ¾ cup unsalted butter, softened

  • ¾ cup brown sugar, packed

  • ½ cup granulated sugar

  • 2 large eggs

  • 2 teaspoons vanilla extract

  • 1 cup M&M’s candies


Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or lightly grease it.

  2. In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.

  3. In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.

  4. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.

  5. Gradually add the dry ingredients to the wet mixture, mixing until just combined.

  6. Fold in the M&M’s candies, reserving a few to sprinkle on top before baking.

  7. Spread the dough evenly into the prepared baking pan and press the reserved M&M’s on top.

  8. Bake for 25–30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.

  9. Allow the bars to cool in the pan before slicing into squares.

Notes

For a festive touch, use seasonal M&M’s (like red and green for Christmas or pastels for Easter).

Add-ins like chopped nuts, chocolate chips, or a swirl of peanut butter can be mixed into the dough for extra flavor.

Store leftovers in an airtight container at room temperature for up to 5 days.

To freeze, wrap individual bars tightly in plastic wrap and place them in a freezer-safe bag. They can be frozen for up to 3 months.
