Gluten-Free Peanut Butter Marshmallow
Gluten-Free Peanut Butter Marshmallow Cookies became the unexpected star of a chilly Sunday baking exchange hosted in my friend Nora’s small city apartment. The guest list included a marathon runner experimenting with gluten-free eating, a preschool teacher who never arrives without sprinkles, and Nora’s brother who evaluates every dessert like a food critic.
Grocery bags filled the kitchen counter while mugs of cinnamon tea warmed cold hands. Someone placed a jar of peanut butter beside a bowl of marshmallows and the conversation instantly shifted toward cookies.
The room buzzed with ideas while rain tapped gently against the windows. A baking tray rotated between us as everyone debated texture preferences. Some wanted soft cookies, others insisted on crispy edges.
The frozen marshmallow trick became the day’s experiment and suddenly the kitchen turned into a mini test lab. Laughter echoed as dough clung to spatulas and flour dusted the countertop like powdered sugar snow.
When the cookies baked, the aroma wrapped around the apartment and drifted into the hallway. Conversations paused as the oven light flickered on and golden edges appeared. A warm tray landed in the middle of the table and the room fell quiet for the first bite. Gluten-Free Peanut Butter Marshmallow Cookies delivered chewy centers, melty pockets, and toasted peanut notes that sparked instant approval from everyone gathered around.

Key Ingredients
- 1 ¼ cup gluten-free flour

- ½ cup granulated sugar
- ¾ cup brown sugar, packed
- ¾ cup creamy peanut butter
- 1 large egg

- 1 ¼ cups mini marshmallows, frozen
Tools Needed
- Mixing bowls
- Hand mixer or electric mixer
- Whisk
- Baking sheet
- Cookie scoop or spoon
- Parchment paper
- Airtight container
Cooking Instructions
Step 1: Freeze the Marshmallows
Place mini marshmallows in an airtight container and freeze for a few hours. This prevents them from melting into the dough too quickly.
Step 2: Preheat the Oven
Preheat oven to 350°F. Line a baking sheet with parchment paper.
Step 3: Mix Dry Ingredients
Whisk flour, baking soda, and sea salt in a medium bowl until evenly combined.
Step 4: Cream Butter and Sugars
Using a hand mixer, beat butter, granulated sugar, and brown sugar until light and fluffy. This takes about 2 to 3 minutes.
Step 5: Add Peanut Butter and Flavoring
Mix in peanut butter, egg, and vanilla extract until smooth and creamy.
Step 6: Fold in Frozen Marshmallows
Remove marshmallows from freezer and quickly fold into the wet mixture.
Step 7: Combine Dough
Add dry ingredients gradually and mix until a soft dough forms. If dough feels sticky, add 1 tablespoon flour at a time.
Step 8: Scoop Cookies
Use a large cookie scoop to portion dough into balls about 2 to 3 tablespoons each. Space 1 to 2 inches apart.
Step 9: Bake
Bake for 10 to 11 minutes until edges are golden and centers appear slightly soft.
Step 10: Cool
Allow cookies to cool for 10 minutes on the tray before transferring.
Step 11: Store
Store in airtight container in refrigerator up to one week.
