How to Make Peanut Butter Marshmallow Cookies
-
Prepare the Marshmallows: Start by adding your mini marshmallows to an airtight container and placing them in the freezer for a few hours. This keeps them from melting too quickly during baking.
-
Preheat the Oven: Set your oven to 350°F. This temperature is ideal for achieving the perfect cookie texture—soft on the inside and slightly crisp on the outside.
-
Mix the Dry Ingredients: In a medium-sized bowl, whisk together 1 ¼ cups of gluten-free flour, 1 teaspoon of baking soda, and ½ teaspoon of sea salt. This blend sets the foundation for your cookie dough.
-
Cream the Butter and Sugars: In a large bowl, use a hand mixer to whisk together ½ cup of unsalted butter and both sugars—½ cup granulated and ¾ cup packed brown sugar—until they’re well combined and fluffy.
-
Add the Wet Ingredients: To the butter-sugar mixture, add ¾ cup of creamy peanut butter, 1 large egg, and 2 teaspoons of vanilla extract. Mix until everything is fully incorporated, forming a smooth, creamy batter.
-
Incorporate the Frozen Marshmallows: Retrieve the marshmallows from the freezer and gently fold them into the batter. Do this quickly to avoid defrosting them before they enter the oven.
-
Combine the Mixtures: Gradually add the dry flour mixture to the wet ingredients, stirring until you have a thick, cohesive batter. You’ll know it’s ready when it clumps together beautifully.
-
Prep the Baking Sheet: Line a baking sheet with parchment paper to prevent sticking and make cleanup easier; this simple step ensures your cookies slide off effortlessly.
-
Scoop the Cookie Dough: Use a cookie scoop to portion out the dough, placing each ball about 1-2 inches apart on the baking sheet. This gives them room to spread while baking.
-
Bake to Perfection: Pop your cookies into the oven and bake them for 10-11 minutes. Keep an eye out for a lightly golden edge!
-
Cool and Enjoy: Once done, remove the cookies from the oven and let them cool for about 10 minutes before serving. This cooling period makes them easier to handle and allows those gooey marshmallows to settle.
-
Store Leftovers Properly: If you have any cookies left (which is rare!), store them in an airtight container in the fridge for up to one week to maintain their fresh, chewy goodness.
Optional: Drizzle with melted chocolate for an extra touch of indulgence!

Expert Tips for Peanut Butter Marshmallow Cookies
-
Chill the Marshmallows: Make sure to freeze the mini marshmallows for several hours beforehand; this prevents them from melting into the dough too quickly during baking.
-
Perfect Baking Time: Keep an eye on your cookies as they bake. Ovens can vary, so if you see a lightly golden edge at about 10 minutes, they’re likely ready for cooling.
-
Watch the Dough Consistency: Avoid over-mixing the flour with the wet ingredients; this can lead to dense cookies. Just mix until combined for the best peanut butter marshmallow cookies!
-
Space Them Out: Be sure to place the cookie dough balls 1-2 inches apart on the baking sheet. This gives them room to spread while baking and helps achieve that perfect texture.
-
Store Wisely: If you have leftovers, keep them in an airtight container in the fridge. They’ll stay fresh and chewy for up to a week, making them a convenient treat for any moment!

Make Ahead Options
These Peanut Butter Marshmallow Cookies are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the cookie dough up to 24 hours in advance by mixing it as directed and then refrigerating the batter in an airtight container. This helps keep the dough fresh and ensures those mini marshmallows stay nice and chewy. When ready to bake, simply preheat the oven to 350°F and scoop the chilled dough onto your parchment-lined baking sheet. Bake for the same 10-11 minutes for delicious cookies just as good as fresh! Just be sure to let the dough sit at room temperature for about 10 minutes before scooping to maintain the cookies’ delightful texture.
How to Store and Freeze Peanut Butter Marshmallow Cookies
Room Temperature: For optimal texture, store cookies in an airtight container at room temperature for up to 3 days. Enjoy them fresh and chewy!
Fridge: If you want to keep them longer, place the cookies in an airtight container in the fridge for up to 1 week. This helps maintain their gooey marshmallow goodness.
Freezer: Freeze individual cookies in an airtight container or freezer bag for up to 2 months. To enjoy, simply allow them to thaw at room temperature.
Reheating: To bring back the chewy texture, pop the cookies in the microwave for 10-15 seconds. This will warm them up and revive that delightful gooeyness!
Peanut Butter Marshmallow Cookies Recipe FAQs
How can I choose the right gluten-free flour?
Absolutely! When selecting gluten-free flour, look for blends that contain a mix of whole grains and starches for the best results. I often recommend brands like Bob’s Red Mill or King Arthur Flour, which have proven recipes and performance. Ensure it’s labeled specifically as “gluten-free” to avoid any cross-contamination.
What is the best way to store homemade peanut butter marshmallow cookies?
Very! For optimal freshness, store your cookies in an airtight container at room temperature for up to 3 days. If you have leftovers after that, place them in the fridge where they can stay fresh for up to 1 week. Make sure they’re completely cooled before sealing them up to prevent moisture from making them soggy.
Can I freeze peanut butter marshmallow cookies?
Certainly! To freeze the cookies, first let them cool completely. Then, wrap them individually in plastic wrap and place them in an airtight container or freezer bag. They can last up to 2 months in the freezer. When you’re ready to enjoy them, simply let them thaw at room temperature for a couple of hours, or microwave them for 10-15 seconds for that fresh-baked feel.
What should I do if my cookies spread too much while baking?
Oh no! If your peanut butter marshmallow cookies spread excessively, it could be due to too much butter or not chilling the dough long enough. For next time, consider using a little less butter or chilling the dough for 30 minutes before scooping and baking. Be sure to measure your ingredients accurately; sometimes, even a slight change can affect the outcome.
Are there any allergies to consider with this recipe?
Absolutely! This recipe contains peanuts and eggs, so it’s important to be mindful of those with allergies. Instead of creamy peanut butter, you could use almond butter or sun butter to avoid peanut allergies. If someone has egg allergies, flaxseed eggs (1 tablespoon ground flaxseed mixed with 2.5 tablespoons of water) can serve as a great alternative for binding.
What if I can’t find frozen mini marshmallows?
Not an issue! If you can’t find frozen mini marshmallows, you can use regular mini marshmallows and just freeze them yourself. Simply place them in an airtight container for a few hours before incorporating them into your dough. Alternatively, cut larger marshmallows into smaller pieces; just keep in mind they might melt faster, so scoop them in quickly!
