Gluten-Free Peanut Butter Marshmallow Cookies

There is something especially comforting about baking cookies during the holidays. The kitchen fills with the warm aroma of peanut butter and vanilla, the oven keeps the room cozy, and a simple baking day can turn into a memory everyone shares. I love recipes that feel special enough for a holiday cookie tray while still keeping the preparation simple.

These Gluten-Free Peanut Butter Marshmallow Cookies bring that feeling straight to the kitchen. Each cookie combines creamy peanut butter, brown sugar, vanilla, and soft marshmallow pieces inside a tender cookie. The edges bake lightly while the centers stay soft and chewy, creating a texture that feels wonderfully homemade.

The frozen mini marshmallows add a playful touch, too. They help keep their shape long enough to fold into the dough and bake into little pockets of fluffy sweetness. Meanwhile, the peanut butter gives every bite a rich, familiar flavor.

This recipe makes 16 cookies, so it works beautifully for a small holiday gathering, cookie exchange, family dessert, or cozy afternoon treat. If you need a gluten-free cookie that looks inviting and tastes comforting, this recipe deserves a place on your baking list.

Overview of Gluten-Free Peanut Butter Marshmallow Cookies

These Gluten-Free Peanut Butter Marshmallow Cookies use gluten-free flour, creamy peanut butter, butter, two types of sugar, egg, vanilla, and mini marshmallows. You freeze the marshmallows before mixing them into the dough, which makes the preparation a little different from a standard cookie recipe.

The finished cookies have a soft, pillowy texture with chewy centers and sweet marshmallow pieces throughout. Peanut butter leads the flavor, while brown sugar adds a deeper sweetness. Vanilla rounds everything out and gives the cookies a familiar bakery-style aroma.

Because the recipe uses a relatively small ingredient list, you can prepare the dough without a complicated process. Furthermore, the cookies need only about 10 to 11 minutes in the oven. That makes them especially useful when you want a homemade dessert without spending hours in the kitchen.

These cookies also fit naturally into a holiday dessert spread. Their soft texture contrasts nicely with crisp cookies, brownies, and other festive treats. You can serve them slightly warm for a softer marshmallow texture or let them cool completely before storing them.

One important note about the recipe as provided: although the original description labels these cookies “vegan,” the ingredient list contains butter and an egg. Therefore, the recipe as written is not vegan. To make a vegan version, you would need suitable plant-based replacements for both ingredients, and you would also need to use vegan marshmallows.

Ingredients

For 16 cookies, you will need 1 ¼ cups gluten-free flour. You can also use all-purpose flour if gluten-free preparation does not matter for your guests.

Add 1 teaspoon baking soda and ½ teaspoon sea salt to balance the dough and support the cookie texture.

Use ½ cup unsalted butter, softened to room temperature. The softened butter blends more easily with the sugars.

You will also need ½ cup granulated sugar and ¾ cup packed brown sugar. Together, they create the sweetness and soft texture that make these cookies so enjoyable.

Add ¾ cup creamy peanut butter for the main flavor. Creamy peanut butter creates a smooth, consistent dough.

Use 1 large egg to bind the ingredients together, followed by 2 teaspoons vanilla extract for additional flavor.

Finally, prepare 1 ¼ cups mini marshmallows. Freeze the marshmallows for a few hours before you start mixing the dough.

Necessary Tools for Preparation

You will need an airtight container for freezing the mini marshmallows, a medium mixing bowl for the dry ingredients, and a larger bowl for the wet ingredients. A whisk works well for combining the flour, baking soda, and sea salt.

A hand mixer makes it easier to cream the softened butter and sugars. You will also need a spatula or spoon for folding the marshmallows into the dough and combining the flour mixture.

For shaping the cookies, use a large cookie scoop if you have one. The original recipe uses enough dough for cookies measuring about 2 to 3 tablespoons each. A regular spoon can also work.

Finally, prepare a baking sheet and parchment paper. A wire cooling rack can help the cookies cool evenly, although you can also leave them on the baking sheet during the initial cooling period.

Ingredient Additions & Substitutions

• Gluten-free flour: Use a gluten-free flour blend for the gluten-free version. The original recipe also allows all-purpose flour.
• Butter: For a dairy-free version, use a suitable plant-based butter that works for baking.
• Egg: A vegan egg replacement can replace the egg if you want a vegan adaptation, although the texture may change.
• Peanut butter: Creamy peanut butter works best for the smooth dough. If needed, another creamy nut or seed butter can provide a different flavor.
• Mini marshmallows: Use vegan mini marshmallows if you want to make the cookies vegan.
• Sea salt: Regular fine salt can work if sea salt is unavailable.
• Sugar: Keep the granulated and brown sugars in the recipe for the closest match to the original texture and flavor.

If you need to keep the cookies strictly gluten-free, check every packaged ingredient, especially the flour and marshmallows, for appropriate labeling.

Step-by-Step Instructions

Step 1: Prepare the mini marshmallows first. Place them in an airtight container and freeze them for a few hours before baking. This preparation helps keep the marshmallows cold while you mix the cookie dough.

Step 2: When you are ready to bake, preheat the oven to 350°F.

Step 3: Add the gluten-free flour, baking soda, and sea salt to a medium bowl. Whisk everything together until evenly combined, then set the bowl aside.

Step 4: In a larger bowl, whisk the softened butter and both sugars with a hand mixer. Continue until the mixture becomes well incorporated.

Step 5: Add the creamy peanut butter, egg, and vanilla extract. Mix again until the ingredients combine into a smooth, cohesive mixture.

Step 6: Remove the mini marshmallows from the freezer. Add them to the batter and fold them in quickly before they have time to defrost.

Step 7: Add the dry flour mixture to the wet mixture. Mix until a cookie dough forms and the flour disappears into the batter.

Step 8: Line a baking sheet with parchment paper. Use a large cookie scoop to portion the dough into balls. Each portion should contain about 2 to 3 tablespoons of dough.

Step 9: Arrange the dough balls on the prepared baking sheet, leaving approximately 1 to 2 inches between each one. The cookies need room to spread as they bake.

Step 10: Bake the cookies for 10 to 11 minutes. Remove them from the oven while they still look soft in the centers.

Step 11: Let the cookies cool on the baking sheet for about 10 minutes. They will continue baking from the residual heat as they cool.

Step 12: Once the cookies have cooled, serve them and enjoy. Store any leftovers in an airtight container in the refrigerator for up to one week.

Tips for Making Gluten-Free Peanut Butter Marshmallow Cookies

Freeze the marshmallows before you begin the dough. This step matters because the cold marshmallows stay firmer while you fold them into the mixture. Therefore, prepare them several hours ahead if possible.

Use softened butter rather than fully melted butter. Soft butter combines more effectively with the sugars and helps you create the intended cookie texture.

Measure the gluten-free flour carefully. Too much flour can make cookies dense and dry. Spoon the flour into your measuring cup and level the top instead of packing it down.

Do not overmix the dough after adding the flour. Mix only until the ingredients come together. Overworking the dough can affect the final texture.

Keep the marshmallows frozen until you are ready to add them. Then work quickly. If they soften too much before you fold them into the dough, they can become harder to distribute evenly.

Give each dough ball enough space on the baking sheet. The cookies spread during baking, so crowding them can cause them to touch.

Watch the baking time closely. The recipe calls for 10 to 11 minutes, and the cookies should remain soft when they leave the oven. They continue to bake as they cool, so avoid waiting for the centers to look completely firm.

Let the cookies rest on the baking sheet for the full cooling period. Moving them too soon can make them fragile because they remain soft immediately after baking.

Storage Instructions

Allow the cookies to cool completely before storing them. Place them in an airtight container and refrigerate them for up to one week, following the storage guidance provided with the original recipe.

For the best texture, allow refrigerated cookies to sit at room temperature for a short time before serving. You can also gently warm an individual cookie if you prefer a softer texture.

If you plan to prepare the cookies ahead of time, freezing the unbaked dough portions can offer a convenient option. However, the provided recipe does not specify a freezer storage period for the dough, so follow the tested storage directions for your particular ingredients if you choose this method.

Keep the cookies protected from air during storage. An airtight container helps prevent them from drying out and protects their soft texture.

General Information

Peanut butter cookies have long held a familiar place in American home baking. Their appeal comes partly from their straightforward ingredients and partly from the distinctive roasted peanut flavor that peanut butter brings to desserts.

This recipe adds a fun holiday twist by combining peanut butter cookie dough with mini marshmallows. Marshmallows bring softness and sweetness, while peanut butter gives the cookie a richer, more substantial flavor. The combination creates a dessert that feels playful without requiring elaborate decoration.

The gluten-free version relies on gluten-free flour rather than traditional wheat flour. That makes the recipe useful for people who avoid gluten, provided you select ingredients that meet your dietary requirements.

The recipe also demonstrates how small preparation choices can influence cookie results. Freezing the marshmallows before mixing them into the dough gives you more control during preparation. Likewise, allowing the cookies to finish setting on the baking sheet helps preserve their soft texture.

These cookies also work well for holiday baking because you can portion the dough ahead of time and bake batches as needed. Their peanut butter flavor makes them easy to recognize, while the marshmallow pieces give them an unexpected detail that can make a cookie tray more interesting.
