Step‑by‑Step Instructions for Butter Marshmallow Cookies
Step 1: Freeze the Marshmallows
Begin by placing your mini marshmallows in the freezer for at least 2 hours before baking. This crucial step ensures they stay intact during the baking process, allowing for that delightful gooeyness inside your butter marshmallow cookies without becoming a melted mess.
Step 2: Preheat the Oven
Preheat your oven to 350°F (175°C). This temperature is perfect for baking, creating cookies with a lightly crispy edge while keeping the center soft and chewy. As your oven heats up, gather your baking sheet and line it with parchment paper to prevent the cookies from sticking.
Step 3: Prepare the Dry Ingredients
In a medium bowl, whisk together the gluten-free flour, baking soda, and sea salt until well combined. This step ensures that all the dry ingredients are evenly distributed, giving your butter marshmallow cookies structure and flavor. Set the bowl aside while you mix up the wet ingredients.
Step 4: Cream Together Butter and Sugars
In a large bowl, use an electric mixer to beat the softened unsalted butter, granulated sugar, and brown sugar until the mixture is smooth and creamy, about 2-3 minutes. You’re looking for a light and fluffy texture that will contribute to the cookies’ rich, moist interior.
Step 5: Mix in Peanut Butter and Egg
Add the creamy peanut butter to the butter and sugar mixture, along with the large egg and vanilla extract. Mix until thoroughly combined—this should take another 1-2 minutes. The peanut butter adds its signature flavor, making these cookies truly irresistible.
Step 6: Fold in the Frozen Marshmallows
Quickly fold the frozen mini marshmallows into your batter using a spatula. Make sure not to let them sit too long in the batter, as you want them to remain frozen. This will result in delightful pockets of gooeyness in your baked butter marshmallow cookies.
Step 7: Combine Wet and Dry Ingredients
Gradually mix the dry flour mixture into the wet ingredients until just combined. You want a soft dough that holds together well but avoid overmixing to keep your cookies tender. This is the final step before shaping your butter marshmallow cookies!
Step 8: Shape the Cookie Dough
Using a cookie scoop or your hands, portion out the dough into balls, each weighing about 2-3 tablespoons. Place them 1-2 inches apart on the prepared baking sheet. This gives each cookie space to spread out and bake evenly while developing that lovely golden color.
Step 9: Bake the Cookies
Slide the baking sheet into the preheated oven and bake for 10-11 minutes. Keep an eye on the cookies; they’re ready when the edges are lightly golden but the centers still look soft. This slight underbaking ensures they remain chewy after cooling.
Step 10: Cool and Enjoy
Once done, allow the cookies to cool on the baking sheet for about 10 minutes before transferring them to a wire rack. This cooling time helps them firm up slightly while retaining their gooey marshmallow center. Enjoy these delightful butter marshmallow cookies!

Expert Tips for Butter Marshmallow Cookies
-
Chill Your Marshmallows: Ensure mini marshmallows are completely frozen for the perfect chewy center that won’t melt into goo during baking.
-
Cookie Scoop Advantage: Using a cookie scoop guarantees uniform cookie sizes, allowing for even baking and a consistent texture in your butter marshmallow cookies.
-
Watch Baking Time: Keep a close eye on the cookies; removing them when edges are golden but centers are still soft keeps them wonderfully chewy.
-
Don’t Overmix Dough: Combine wet and dry ingredients until just mixed to prevent tough cookies. Overmixing can ruin the tender texture of your butter marshmallow cookies.
-
Let Them Cool: Allow cookies to cool on the baking sheet for 10 minutes before transferring to a wire rack; this helps them maintain their structure and gooiness.
How to Store and Freeze Butter Marshmallow Cookies
Fridge: Store cookies in an airtight container in the fridge for up to 1 week to keep them fresh and chewy.
Freezer: For longer storage, freeze cookies in a single layer on a baking sheet, then transfer to a sealed freezer bag for up to 3 months.
Reheating: To enjoy cookies after freezing, thaw at room temperature or reheat in the microwave for 10-15 seconds; this revives their delightful softness.
Room Temperature: If you plan to eat them quickly, leave cookies at room temperature in an airtight container for up to 3 days, maintaining their delicious texture.

Gluten-Free Peanut Butter Marshmallow Cookies Recipe FAQs
How do I choose the right gluten-free flour?
Absolutely! When selecting gluten-free flour, look for blends that contain ingredients like brown rice, tapioca, and potato starch. These provide better structure and texture. Brands like Bob’s Red Mill or King Arthur Flour offer excellent options. If you’re in a pinch, you can always substitute with all-purpose flour if gluten isn’t a concern!
What’s the best way to store leftover cookies?
Very! To maintain the freshness of your gluten-free peanut butter marshmallow cookies, store them in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the fridge for up to a week, or freeze them for up to 3 months. Just make sure they’re completely cooled before storing.
How do I freeze my cookies for later?
Here’s a step-by-step! First, place your cookies in a single layer on a baking sheet and pop them in the freezer for about 2 hours or until firm. Once frozen, transfer the cookies to a freezer-safe bag or container. Make sure to label it with the date. This method helps preserve their texture and flavor!
What if my cookies spread too much while baking?
Oh no! If your cookies spread excessively, it could be due to a few reasons. Make sure your butter isn’t too soft—aim for room temperature but not melted. Also, chilling the dough for at least 30 minutes before baking can help. If the dough feels very sticky, adding a bit more gluten-free flour can provide the right consistency.
Are these cookies safe for those with nut allergies?
Definitely not! These cookies are made with peanut butter, which poses a risk for nut allergies. If you need a nut-free alternative, you can substitute the peanut butter with sunflower seed butter or soy nut butter. Just ensure the products you choose are processed in a nut-free facility for safety!
