M&M Cookie Bars

M&M Cookie Bars offer a chewy, sweet bar with a tender crumb, enhanced by colorful M&M candies and mini semisweet chocolate chips. The dough blends melted butter with sugars, egg, vanilla, and dry ingredients for a soft texture. Baking until golden with slightly firm edges produces bars that hold together well but remain soft inside. These bars make a straightforward dessert or snack with a balance of sweetness and chocolate pops from the candy pieces.

Description

This recipe starts by combining melted butter with brown and granulated sugars, then mixing in egg and vanilla for moisture and flavor. Flour, salt, and baking soda are folded in gently to avoid overmixing, preserving a tender texture. The addition of both M&M candies and mini chocolate chips distributes chocolate throughout the bars, contributing to their color and flavor variety. Baking in an 8x8-inch pan at 350°F until light golden and edges pull from the pan produces soft yet structured bars.

The result is a sweet cookie bar with a chewy texture and pockets of chocolate from the candies and chips. The combination of melted butter and sugar ratios controls the balance of saltiness and sweetness, and using salted butter is an option depending on personal preference. These bars are convenient for portioning and sharing, suitable as a snack or dessert.

Accurate flour measurement is important to keep the bars soft rather than dry. Gently mixing by hand helps avoid tough bars by preventing excess gluten development.

Ingredients

Servings
  • 6 tablespoons butter melted and cooled slightly
  • 1/2 cup brown sugar packed
  • 1/4 cup granulated sugar
  • 1 egg large
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1/4 teaspoon baking soda
  • 1/2 cup M&M candies
  • 1/4 cup mini semisweet chocolate chips

Instructions

  1. Adjust the oven rack to middle position. Preheat the oven to 350 F.
  2. Grease an 8X8-inch metal pan. Set aside.
  3. Whisk the melted butter and sugars in a large bowl until combined.
  4. Add the egg and vanilla and mix well.
  5. Using a rubber spatula, fold the flour, salt, and baking soda into the butter mixture until just combined; do not overmix.
  6. Fold in the M&Ms and chocolate chips.
  7. Pour the batter into the prepared pan, smoothing the top with the spatula.
  8. Bake until the top of the bars is light golden brown, slightly firm to the touch, and edges start pulling away from sides of pan, about 15-25 minutes.
  9. Cool on a wire rack to room temperature.

Notes

  • Use salted butter for a balanced sweet-salty flavor or unsalted butter and omit added salt for a sweeter bar.
  • Measure flour by lightly spooning it into the measuring cup and leveling to maintain bar softness.
  • Mix the dough gently by hand to prevent overworking and tough texture.
  • M&Ms can be substituted with seasonal flavors, and mini chocolate chips are preferred for even chocolate distribution.
  • Melt butter just until liquefied to speed mixing without overheating.
