Ingredients

Scale

Main Cookie Ingredients:

  • 2 14 cups all-purpose flour
  • 1 cup (2 sticks) unsalted butter, melted
  • 2 large eggs

Sugars:

  • 1 cup light brown sugar, packed
  • 1/2 cup granulated sugar

Flavor and Mix-ins:

  • 1 1/2 cups M&Ms (regular or mini)
  • 1/2 cup semi-sweet chocolate chips
  • 2 teaspoons vanilla extract
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt

Decoration:

  • Extra M&Ms for sprinkling on top

Instructions

  1. Prepare the baking setup by preheating the oven to 350F (175C) and lining a 9×13-inch pan with parchment paper or greasing it thoroughly.
  2. Create a smooth base by whisking melted butter with brown and granulated sugars until fully integrated and glossy.
  3. Incorporate eggs individually into the sugar mixture, ensuring complete blending after each addition, then mix in vanilla extract for aromatic depth.
  4. Separately combine flour, baking soda, and salt, creating a uniform dry ingredient mixture.
  5. Gradually merge dry ingredients into the wet mixture, stirring carefully to prevent overmixing and maintain a consistent texture.
  6. Gently fold chocolate chips and M&Ms into the dough, distributing them evenly throughout the batter.
  7. Transfer the cookie dough into the prepared pan, using a spatula to spread it uniformly and create an even surface.
  8. Strategically scatter additional M&Ms across the top of the dough for visual appeal and extra candy bursts.
  9. Bake for 25-30 minutes, watching for golden edges and checking doneness with a toothpick that should emerge with minimal moist crumbs.
  10. Remove from oven and allow complete cooling in the pan to ensure proper setting and easy cutting of bars.

Notes

  • Chill the dough for 30 minutes before baking to prevent excessive spreading and create thicker, chewier bars.
  • Use room temperature eggs to ensure smoother mixing and more even baking of the cookie bars.
  • Swap some all-purpose flour with whole wheat flour for a nuttier flavor and added nutrition without compromising texture.
  • For gluten-free version, replace all-purpose flour with a 1:1 gluten-free baking blend to maintain the same delicious taste and texture.
