These chewy peanut butter marshmallow cookies combine soft, pillowy texture with gooey marshmallow pockets and rich peanut butter flavor, perfect for cozy sweet moments.

Ingredients

Scale
  • 1 cup creamy peanut butter (smooth or chunky)
  • 3/4 cup granulated sugar
  • 1/2 cup packed brown sugar
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup mini marshmallows

Instructions

  1. Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.
  2. In a medium bowl, combine peanut butter, granulated sugar, and brown sugar. Cream together using an electric mixer or wooden spoon until smooth and slightly fluffy, about 2-3 minutes.
  3. Add the egg and vanilla extract to the mixture and beat until well combined and glossy.
  4. In a separate small bowl, whisk together baking soda and salt. Slowly add to the wet mixture, stirring gently until just incorporated. Avoid overmixing.
  5. Gently fold in the mini marshmallows using a spatula, distributing them evenly.
  6. Scoop dough balls about 1 1/2 inches in diameter using a tablespoon or cookie scoop. Place them 2 inches apart on the prepared baking sheets.
  7. Bake for 9-11 minutes until edges look set but centers remain soft. Marshmallows may puff slightly and get a light golden tint.
  8. Let cookies rest on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

Notes

If marshmallows brown too fast, lower oven temperature or cover loosely with foil halfway through baking. Use room temperature egg and peanut butter for smooth mixing. Fold marshmallows gently to keep chewy pockets intact. Dough can be refrigerated up to 24 hours before baking.
