Gooey Roasted Marshmallow M&M Cookie Bars

Marshmallows are baked into an M&M cookie base, making the perfectly toasted marshmallow gooey cookie bars.
Prep Time10 mins
Cook Time25 mins
Total Time35 mins
Servings: 24 bars


  • 1 cup (2 sticks) unsalted butter, softened
  • 1 cup dark brown sugar
  • 1 cup granulated sugar
  • 3 large eggs
  • 2 teaspoons pure vanilla extract
  • 2 1/2 cups all-purpose flour
  • 2 teaspoons baking soda
  • 1 teaspoon salt
  • 1 cup miniature M&M's
  • 24 jumbo (regular size) marshmallows


  • Preheat oven to 375 degrees F. Lightly grease a 9x13-inch baking pan with nonstick spray (I recommend Baker's Joy).
  • In a large mixing bowl, beat together the butter and sugars until creamy, about 2 minutes. Add the eggs, one at a time, beating after each addition. Mix in the vanilla.
  • In a separate medium bowl, whisk together the flour, baking soda and salt. Gradually add to the wet ingredients and beat until just combined. Gently mix in the M&M's until evenly distributed.
  • Press just less than 3/4 of the cookie dough evenly into the bottom of the prepared baking pan. Layer the 24 marshmallows into the pan, spacing evenly into a 4x6 grid. Use a medium cookie scoop or ice cream scoop to spoon dough balls in between each marshmallow in the 6-count rows, creating 20 dough balls (5 in each row).
  • Bake for 25 minutes, or until the marshmallows and cookie dough are dark golden brown. Let cool before slicing into 24 squares.
