Chewy, gooey cookies featuring Reese’s peanut butter chips and mini marshmallows for a perfect sweet and nostalgic treat.

Ingredients

Scale
  • 2 ½ cups (312 grams) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup (226 grams) unsalted butter, softened
  • ¾ cup (150 grams) granulated sugar
  • ¾ cup (165 grams) packed light brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1 ½ cups (270 grams) Reese’s peanut butter chips
  • 1 cup (about 50 grams) mini marshmallows

Instructions

  1. Preheat your oven to 350°F (177°C). Line two baking sheets with parchment paper or silicone mats.
  2. In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
  3. In a large bowl, beat the softened butter, granulated sugar, and light brown sugar until light and fluffy, about 3 to 5 minutes.
  4. Beat in the eggs one at a time, then stir in the vanilla extract until fully combined.
  5. Gradually add the flour mixture to the wet ingredients, mixing on low speed or folding with a spatula just until combined. Avoid overmixing.
  6. Gently fold in the Reese’s peanut butter chips and mini marshmallows, distributing evenly without crushing the marshmallows.
  7. Using a cookie scoop or tablespoon, drop generous mounds about 2 inches apart on the prepared baking sheets.
  8. Bake for 10 to 12 minutes, until edges are golden but centers look slightly soft. Marshmallows will puff and get a light golden tint.
  9. Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Notes

For extra thick and chewy cookies, chill the dough for 30 minutes before baking. Avoid overbaking to prevent marshmallows from burning. Use room temperature eggs for best texture. Fold in mix-ins gently to keep marshmallows intact. Parchment paper or silicone mats prevent sticking and make cleanup easier.
