I can’t get enough of the way the flavors come together in this recipe. The peanut butter adds a deep nuttiness and creaminess, while the mini marshmallows provide surprise bursts of fluffiness and sweetness that melt just right in your mouth.

I love serving these at casual family gatherings, holiday parties, or anytime I want to surprise my loved ones with a cookie that’s a cut above the usual.

Ingredients You’ll Need

Every ingredient in this recipe plays a special role in creating the ideal texture and flavor. They’re simple, pantry-friendly staples that come together beautifully to make these cookies irresistible.

• 1 ¼ Cups Gluten-Free Flour: Provides the perfect base with a tender crumb, but you can use all-purpose flour if you prefer.
• 1 Teaspoon Baking Soda: Helps the cookies rise nicely and get that light, soft texture.
• ½ Teaspoon Sea Salt: Balances the sweetness and enhances all the rich flavors.
• ½ Cup Unsalted Butter, softened: Adds richness and that melt-in-your-mouth quality.
• ½ Cup Granulated Sugar: For just the right amount of sweetness and a slight crunch on the edges.
• ¾ Cup Brown Sugar, packed: Brings moisture and a subtle caramel undertone.
• ¾ Cup Creamy Peanut Butter: The star ingredient that makes these cookies uniquely comforting and delicious.
• 1 Large Egg: Binds everything together and adds structure.
• 2 Teaspoons Vanilla Extract: Infuses warmth and depth of flavor.
• 1 ¼ Cups Mini Marshmallows, frozen: The magical ingredient that creates delightful gooey pockets throughout the cookie.

Directions

Step 1: Start by placing the mini marshmallows into an airtight container and pop them in the freezer for a few hours. Freezing helps them keep their little shape so they don’t melt completely into the dough later.

Step 2: Preheat your oven to 350 degrees Fahrenheit. This ensures your oven is perfectly hot when the cookies go in, so they bake evenly.

Step 3: In a medium bowl, whisk together the gluten-free flour, baking soda, and sea salt. Set this dry mixture aside for a moment.

Step 4: In a larger bowl, use a hand mixer to cream together the softened butter with both sugars until the mixture becomes light, fluffy, and well combined—this usually takes about two minutes.

Step 5: Add in the creamy peanut butter, egg, and vanilla extract to the butter-sugar mixture and continue mixing until smooth and fully incorporated.

Step 6: Quickly remove the marshmallows from the freezer and fold them gently but quickly into the wet batter before they start to thaw, preserving their giant melty texture.

Step 7: Add the flour mixture to the wet ingredients and mix until a soft cookie dough forms. Don’t overmix here — just combine until no dry streaks remain.

Step 8: Line a baking sheet with parchment paper to prevent sticking. Use a large cookie scoop, or about 2-3 tablespoons of dough per cookie, and place scoops 1-2 inches apart on the sheet to allow room for spreading.

Step 9: Bake your cookies for 10 to 11 minutes. The edges will look set but the centers will be soft and puffy—that’s exactly what you want.

Step 10: Remove the cookies from the oven and allow them to cool on the baking sheet for about 10 minutes. This resting time lets them finish baking gently and firm up without losing that soft chew.

Step 11: Transfer the cookies to a wire rack to cool completely or serve warm to enjoy the gooey marshmallow magic at its peak.

Servings and Timing

This recipe yields approximately 18 to 20 scrumptious cookies—perfect for sharing or enjoying throughout the week. Prep time is about 15 minutes, plus the freezing time for marshmallows which I recommend planning ahead for at least 2 hours. Baking takes 10 to 11 minutes per batch. Overall, from start to finish, you should allot roughly 30 minutes of active time, not including marshmallow freezing, to enjoy this delightful treat.

How to Serve This My Favorite Gluten-Free Peanut Butter Marshmallow Cookies Recipe

I love serving these cookies fresh and slightly warm so the marshmallows are perfectly gooey. They’re wonderful on their own, but pairing them with a cold glass of milk truly takes the experience over the top. For an adult twist, I often enjoy them alongside a robust cup of coffee or even a lightly sweet dessert wine like a late harvest Riesling.

If I’m preparing for a party or family gathering, I like arranging these cookies on a decorative platter, sprinkling a pinch of flaked sea salt on top before serving to amplify the peanut-buttery richness, and offering small napkins so everyone can savor them mess-free. These cookies also complement holiday cookie trays beautifully, especially when mixed with other gluten-free treats for friends and loved ones with varied tastes.

For a cozy night in, I sometimes warm a few cookies in the microwave for 10 seconds and serve with a scoop of vanilla ice cream or alongside a cup of hot cocoa for the ultimate comfort dessert. Room temperature works well too, especially if you plan to pack them up for a picnic or snack on-the-go, making them incredibly versatile in how you serve them.

Variations

I’m always experimenting with ways to switch things up while keeping that comforting essence of My Favorite Gluten-Free Peanut Butter Marshmallow Cookies Recipe. If you want to try different nut butters, almond or cashew butter both work beautifully for a varied flavor profile. Just be mindful of the consistency as smoother butters yield softer cookies while chunkier textures create added bite.

For those who prefer vegan treats, you can easily swap the butter with a non-dairy alternative like coconut oil or vegan margarine, and replace the egg with a flax or chia egg. I find that using a slightly larger marshmallow or vegan marshmallows can keep that melty charm intact. The beauty is that this cookie dough is pretty forgiving and adapts well.

Feeling adventurous? Add in chocolate chips or chopped peanuts to the dough for extra crunch and bursts of chocolate alongside the marshmallow. Alternatively, try baking these cookies in a mini muffin tin for a more uniform shape that’s perfect bite-sized finger food. Each cooking method delivers a slightly different experience but keeps the core deliciousness intact.

Storage and Reheating

Storing Leftovers

The best way I found to keep these cookies fresh is to store them in an airtight container in the refrigerator. They’ll stay soft and tasty for up to one week. I recommend placing a piece of parchment paper between layers to prevent sticking, especially with those sticky marshmallow pockets. This helps maintain their lovely texture and flavor until you’re ready for more.

Freezing

Yes, you can absolutely freeze these cookies! I suggest freezing them in a single layer on a baking sheet first to avoid clumping, then transferring them to a freezer-safe container or bag once firm. Properly stored, they’ll keep well for up to 3 months. When you want a treat, just thaw at room temperature for 30-60 minutes and enjoy as if freshly baked.

Reheating

When warming leftovers, I prefer using a microwave for about 10-15 seconds to soften the marshmallows again without melting the cookie entirely. Avoid overheating as the cookies can dry out or become too crumbly. Alternatively, a quick reheat in a 300-degree oven for 5 minutes works wonderfully to revive the soft and gooey texture without sacrificing chewiness.

FAQs

Can I use regular flour instead of gluten-free flour?

Absolutely! While this recipe is designed to be gluten-free, swapping in all-purpose flour works just fine if gluten is not a concern. Just be sure to use the same measurement, and your cookies will remain soft and delicious.

Do I have to freeze the mini marshmallows before adding them to the dough?

Freezing the mini marshmallows helps prevent them from melting completely into the dough, so you get those delightful pockets of gooey marshmallow after baking. It’s a small extra step that really pays off in texture and flavor.

Can I make these cookies vegan?

Yes! You can substitute the butter with vegan margarine or coconut oil and replace the egg with a flax or chia egg. Just make sure your marshmallows are vegan, as some contain gelatin. This way, you keep the recipe inclusive and just as tasty.

How long do these cookies stay fresh?

Stored in an airtight container in the fridge, these cookies stay fresh and soft for up to seven days. If kept at room temperature without refrigeration, the marshmallow filling can get sticky or lose its texture faster.

Can I add mix-ins like chocolate chips or nuts?

Definitely! Adding chocolate chips or chopped nuts pairs beautifully with peanut butter and marshmallow. I recommend folding them in along with the marshmallows for even distribution and extra flavor complexity.
