Prepare Marshmallows: Begin by adding the mini marshmallows to an airtight container and place them in the freezer for a few hours. This step ensures they stay fluffy and create delightful pockets of gooeyness in your cookies.

Mix Dry Ingredients: In a medium bowl, whisk together the gluten-free flour, baking soda, and sea salt. Set it aside and let these ingredients mingle for a bit.
-
Cream Butter and Sugars: In a larger bowl, whisk together the softened butter, granulated sugar, and brown sugar using a hand mixer. Mix until it looks creamy and well incorporated—this is where the magic begins!

Incorporate Wet Ingredients: Add in the creamy peanut butter, large egg, and vanilla extract. Mix everything until it’s fully combined; you want this mixture to be smooth and inviting.
-
Fold in Marshmallows: Remove the marshmallows from the freezer and fold them into your batter quickly. Be sure to act swiftly to keep them from defrosting too much, ensuring those lovely gooey bits stay intact.

Combine Mixtures: Gradually add the flour mixture into the bowl with the wet ingredients. Mix until a deliciously thick batter forms, staying true to that classic cookie dough texture.
-
Prepare Baking Sheet: Line a baking sheet with parchment paper to prevent sticking and make cleanup a breeze.

Shape Cookies: Use a cookie scoop to portion out the dough into balls of about 2-3 tablespoons each. Space them 1-2 inches apart on the baking sheet; they will spread slightly as they bake.

Bake Cookies: Bake the cookies for 10-11 minutes, or until they’re lightly golden around the edges. Once out of the oven, let them cool for another 10 minutes on the baking sheet—this helps them set up perfectly.

Tips for the Best Peanut Butter Marshmallow Cookies
-
Chill the Marshmallows: Ensure you freeze the mini marshmallows for a few hours. This keeps them from melting into the batter too quickly, giving you pockets of gooey goodness.
-
Use Room Temperature Butter: Softened butter combines more easily with the sugars, creating a smoother cookie dough. Take your butter out ahead of time for the best results!
-
Don’t Overmix: When combining the dry ingredients with the wet, mix until just combined. Overmixing can lead to tougher cookies, diminishing that perfect chewy texture.
-
Even Spacing: Make sure to space your cookie dough balls 1-2 inches apart on the baking sheet. This allows them to spread properly while baking, ensuring even cooking.
-
Cool on the Sheet: Remember to let your cookies cool on the baking sheet for 10 minutes before transferring them. This helps them set and prevents breaking.
With these simple tips, your Peanut Butter Marshmallow Cookies will be the star of any snack time!

Peanut Butter Marshmallow Cookies Recipe FAQs
What type of peanut butter is best for these cookies?
I highly recommend using creamy peanut butter for these cookies! It blends seamlessly into the dough, providing that rich, nutty flavor. Crunchy peanut butter can work too, adding a delightful texture, but be aware that it may alter the consistency slightly.
How do I know when my marshmallows are properly frozen?
You’ll want to freeze the mini marshmallows for at least a few hours until they are firm and icy. This ensures they hold their shape in the batter. If they start to defrost, they may stick together, losing that wonderful gooeyness we love in each cookie.
How should I store my Peanut Butter Marshmallow Cookies after baking?
Keep the cookies in an airtight container at room temperature for up to 3 days. Keeping them sealed helps maintain their soft and chewy texture. If you want them to last longer, you can store them in the fridge for up to a week. Just let them sit at room temperature for a bit before enjoying.
Can I freeze the cookie dough before baking?
Absolutely! To freeze the cookie dough, scoop it onto a baking sheet lined with parchment paper and freeze until firm. Then, transfer the cookie dough balls to a freezer-safe bag or container. They can be frozen for up to 3 months. When you’re ready to bake, just place the frozen dough balls directly on the baking sheet and bake for an additional minute or two—perfect for whenever those cookie cravings hit!
Are these cookies suitable for people with nut allergies?
Unfortunately, these Peanut Butter Marshmallow Cookies contain peanut butter, which may not be safe for those with nut allergies. However, you can try substituting the peanut butter with a sunflower seed butter or a similar alternative, but be sure to check ingredients for cross-contamination with nuts.
What should I do if my cookies turn out too dry?
If your cookies end up dry, it’s often due to overmixing or overbaking. Make sure to mix the dough just until combined and check them in the oven a minute or two before the 10-11 minute mark. If you find that your cookies are still dry, consider adding a touch more peanut butter or even a splash of milk next time to achieve that perfect chewy texture!
