Ingredients

Scale

Dry Ingredients

  • 1 ¼ Cup 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 Brown Sugar, packed
  • 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 them from melting too quickly during baking.
  2. Preheat Oven: When ready, preheat your oven to 350°F (177°C) to prepare for baking the cookies.
  3. Mix Dry Ingredients: In a medium bowl, whisk together the gluten-free flour, baking soda, and sea salt until fully combined. Set aside.
  4. Cream Butter and Sugars: In a larger bowl, use a hand mixer to beat the softened butter, granulated sugar, and brown sugar until creamy and well incorporated.
  5. Add Wet Ingredients: To the butter mixture, add the creamy peanut butter, egg, and vanilla extract. Mix again until thoroughly combined.
  6. Fold in Marshmallows: Remove the frozen mini marshmallows from the freezer and quickly fold them into the wet mixture before they defrost, ensuring they remain intact.
  7. Combine Mixtures: Add the dry flour mixture to the wet ingredients and stir until a smooth cookie dough batter forms.
  8. Prepare Baking Sheet: Line a baking sheet with parchment paper to prevent sticking.
  9. Scoop Dough: Using a large cookie scoop (about 2-3 tablespoons), portion dough balls onto the baking sheet, spacing them 1-2 inches apart to allow for spreading.
  10. Bake Cookies: Bake in the preheated oven for 10-11 minutes until the edges are set but the centers remain soft.
  11. Cool Cookies: Remove the baking sheet from the oven and allow the cookies to cool on the sheet for 10 minutes; this resting time lets them finish baking and firms them up.
  12. Serve and Store: Enjoy the cookies warm or at room temperature. Store any leftovers in an airtight container in the refrigerator for up to one week.

Notes

  • Freezing mini marshmallows before adding them to the dough helps maintain their shape and prevents excessive melting during baking.
  • If you don’t have a cookie scoop, use a tablespoon to portion out dough evenly.
  • These cookies will be soft and chewy; avoid overbaking to maintain this texture.
  • Gluten-Free flour can be substituted with all-purpose flour if gluten restrictions are not required.
  • Storing the cookies in the fridge helps retain freshness and texture for up to a week.
