Ingredients

Cookie Bars

  • 2 sticks unsalted butter (at room temperature)
  • 1 cup granulated sugar
  • 1 cup golden brown sugar (firmly packed)
  • 3 large eggs
  • 1 1/2 teaspoons pure vanilla extract
  • 3 cups all-purpose flour
  • 3/4 teaspoon baking soda
  • 3/4 teaspoon salt
  • 1 1/2 cups M&M’s (plus more for topping)
  • 1 cup mini chocolate chips (plus more for topping)

Instructions

  1. Preheat Oven: Preheat your oven to 350 degrees Fahrenheit to ensure it’s ready for baking the cookie bars.
  2. Prepare Baking Dish: Line a 9×13-inch baking dish with foil, leaving some overhang on the sides for easy removal after baking. Generously spray the foil with nonstick cooking spray to prevent sticking.
  3. Mix Butter and Sugars: In the bowl of a stand mixer, beat the room temperature unsalted butter, granulated sugar, and golden brown sugar together on medium speed until the mixture is fluffy and light in texture.
  4. Add Eggs and Vanilla: Add the eggs one at a time along with the vanilla extract into the butter and sugar mixture, continuing to beat until fully incorporated and smooth.
  5. Combine Dry Ingredients: Reduce the mixer speed to low. Gradually add the all-purpose flour, baking soda, and salt to the wet ingredients. Mix until just combined and no dry flour streaks remain.
  6. Fold in Mix-ins: Gently fold in the M&M’s and mini chocolate chips, reserving some to sprinkle on top of the dough for an appealing look and extra chocolatey bites.
  7. Transfer Dough: Spread the cookie dough evenly into the prepared baking dish, pressing it down lightly to form an even layer. Sprinkle the reserved M&M’s and mini chocolate chips evenly over the top and press them down slightly.
  8. Bake: Place the baking dish in the preheated oven and bake for 30 to 35 minutes. The bars should be light golden brown and just set in the center when done.
  9. Cool and Serve: Allow the cookie bars to cool completely in the baking dish before lifting them out using the foil overhang. Cut into 18 bars and serve.

Notes

  • Make sure the butter is at room temperature for easy mixing and better texture.
  • Do not overmix the flour to prevent tough cookie bars.
  • You can use regular chocolate chips if minis are not available.
  • Cooling completely is key for clean cuts and bars that hold together well.
  • Store baked bars in an airtight container at room temperature for up to 4 days.
