Easy peanut butter chocolate marshmallow cookies that bake up soft and chewy with gooey marshmallow pockets and melty chocolate chunks. A quick, comforting treat perfect for any occasion.

Ingredients

Scale
  • 1 cup 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 1/2 cups all-purpose flour (190 g) or gluten-free 1:1 blend
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup mini marshmallows (or chopped regular marshmallows)
  • 1 cup chocolate chips (semi-sweet or milk chocolate)
  • Optional: chopped peanuts for crunch
  • Optional: sprinkle of sea salt on top before baking

Instructions

  1. Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats.
  2. In a large bowl, cream together peanut butter, granulated sugar, and brown sugar using an electric mixer or sturdy spoon until smooth and creamy, about 2-3 minutes.
  3. Add the egg and vanilla extract to the peanut butter mixture and mix until fully combined.
  4. In a separate bowl, whisk together flour, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet mixture, stirring gently until no flour streaks remain. Avoid overmixing.
  6. Fold in mini marshmallows and chocolate chips gently to distribute evenly without squishing the marshmallows.
  7. Drop rounded tablespoon-sized mounds of dough about 2 inches apart onto prepared baking sheets. Optionally, sprinkle a pinch of sea salt on each mound.
  8. Bake for 10-12 minutes until edges look set but centers remain soft.
  9. Cool cookies on the baking sheet for 5 minutes before transferring to a wire rack to finish setting.

Notes

If dough is too sticky to scoop, chill for 15 minutes before baking. Tent cookies with foil if marshmallows brown too quickly. Use room temperature egg for best texture. Avoid overmixing after adding flour to keep cookies soft. Store in airtight container at room temperature for up to 3 days or freeze for up to 2 months.
