Ingredients

Scale

Dry Ingredients

  • 1 ¼ Cups Gluten-Free Flour (can substitute all-purpose flour)
  • 1 Teaspoon Baking Soda
  • ½ Teaspoon Sea Salt

Wet Ingredients

  • ½ Cup Unsalted Butter, softened
  • ½ Cup Granulated Sugar
  • ¾ Cup Packed Brown Sugar
  • ¾ Cup Creamy Peanut Butter
  • 1 Large Egg
  • 2 Teaspoons Vanilla Extract

Add-ins

  • 1 ¼ Cups Mini Marshmallows, frozen

Instructions

  1. Prepare Marshmallows. Place the mini marshmallows in an airtight container and freeze them for a few hours before baking to prevent melting too quickly in the cookies.
  2. Preheat Oven. Set your oven to 350°F (175°C) to ensure it’s ready for baking once the dough is prepared.
  3. Mix Dry Ingredients. In a medium bowl, whisk together the gluten-free flour, baking soda, and sea salt thoroughly. Set aside.
  4. Cream Butter and Sugars. In a large bowl, use a hand mixer to whip together the softened butter, granulated sugar, and brown sugar until smooth and well combined.
  5. Add Wet Ingredients. To the butter and sugar mixture, add the peanut butter, egg, and vanilla extract. Mix well until completely combined and smooth.
  6. Incorporate Marshmallows. Remove the frozen marshmallows from the freezer and quickly fold them into the wet batter before they thaw to maintain their shape.
  7. Combine Dry and Wet Mixtures. Add the flour mixture into the wet ingredients and mix just until a dough is formed. Avoid overmixing to keep the texture light.
  8. Prepare Baking Sheet. Line a baking sheet with parchment paper to prevent sticking and allow for easy cleanup.
  9. Scoop Dough. Using a large cookie scoop (or spoon), shape dough into balls about 2-3 tablespoons each. Place them on the parchment-lined sheet spaced 1-2 inches apart to allow room for spreading.
  10. Bake Cookies. Bake in the preheated oven for 10-11 minutes until the edges are set and cookies are lightly golden.
  11. Cool Cookies. Remove from oven and let the cookies cool on the baking sheet for about 10 minutes, allowing them to finish baking and firm up.
  12. Serve and Store. Enjoy the cookies warm or at room temperature. Store leftovers in an airtight container in the refrigerator for up to one week.

Notes

  • Freezing the mini marshmallows before folding them into the dough helps them maintain their shape during baking.
  • If you don’t have a cookie scoop, a spoon will work to portion out the dough.
  • These cookies will continue to bake slightly during the cooling period on the baking sheet, so avoid overbaking in the oven.
  • You can substitute gluten-free flour with all-purpose flour if gluten is not a concern.
  • Store cookies in an airtight container in the refrigerator to maintain freshness for up to one week.
