Description

Irresistible M&M cookie bars combine childhood nostalgia with sweet chocolate magic. Colorful candy pieces scattered through buttery dough create a playful dessert that delights you with each chewy, indulgent bite.


Ingredients

Scale

main ingredients:

  • 2 cups all-purpose flour
  • 1 cup unsalted butter
  • 1 cup brown sugar
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 1 bag M&M candies

leavening and flavor enhancers:

  • 1 tsp baking powder
  • 1/2 tsp salt
  • 1 tsp vanilla extract

optional add-ins:

  • 1/2 cup chocolate chips
  • 1 tbsp milk (if needed for consistency)

Instructions

  1. Preheat the oven to 350°F and line a 9×13-inch baking pan with parchment paper, allowing slight overhang for easy removal.
  2. Cream together softened butter with brown and granulated sugars until the mixture becomes light and fluffy, creating a smooth base for the cookie bars.
  3. Incorporate eggs one at a time into the butter-sugar mixture, mixing thoroughly after each addition to ensure a uniform texture.
  4. Blend vanilla extract into the wet ingredients, infusing the batter with rich aromatic flavor.
  5. In a separate bowl, whisk together flour, baking powder, and salt to evenly distribute the dry ingredients.
  6. Gradually fold the dry ingredient mixture into the wet ingredients, stirring until just combined to prevent overworking the dough.
  7. If the dough seems too stiff, cautiously add milk to achieve a spreadable consistency.
  8. Transfer the batter into the prepared baking pan, using a spatula to create an even layer across the surface.
  9. Generously sprinkle M&M candies and chocolate chips over the batter, pressing them gently into the surface to ensure they adhere during baking.
  10. Bake for 25-30 minutes, or until the edges turn golden brown and a toothpick inserted in the center comes out with minimal crumbs.
  11. Remove from the oven and allow the bars to cool completely in the pan before lifting out and cutting into squares.
  12. Slice into desired bar sizes and serve at room temperature for optimal texture and flavor.

Notes

  • Soft Texture Secret: Add an extra tablespoon of softened butter or a splash of milk to keep the bars incredibly moist and tender.
  • Color Pop Technique: Reserve a handful of M&Ms to press into the top of the batter just before baking for a vibrant, picture-perfect appearance.
  • Dietary Flexibility: Swap regular flour with gluten-free flour blend for a celiac-friendly version, ensuring everyone can enjoy these delightful treats.
  • Make-Ahead Magic: Wrap the cooled bars tightly in plastic wrap and freeze for up to 3 weeks, creating an instant dessert solution for unexpected guests or sweet cravings.
