Air Fryer Marshmallow Swirl Cookies make me feel accomplished every time I pull them out of the air fryer. The fudgy chocolate base has those beautiful white marshmallow streaks running through it, and the edges get crispy while the centers stay soft. Each bite is rich and sweet with a hint of toasted marshmallow on top. They look impressive but come together so easily.

Whenever I make these air-fried cookies for a weekend get-together, they disappear before I can even grab one for myself. I love that you can prep the dough ahead, bake a batch early, or freeze extras for later. They taste just as fresh once warmed up, making them perfect for any occasion, whether it’s Christmas, a potluck, or just a cozy weekend at home.

How to Make Air Fryer Marshmallow Swirl Cookies with Step-By-Step Instructions
Scroll down for the full recipe card containing a full printable recipe and measurements in both US customary and metric units.
If you follow my simple steps, you’ll see how quick and satisfying these cookies are to make without an oven, from mixing the dough to watching them puff up beautifully in the air fryer.
Combine the Dry Ingredients
Sift together the flour, baking soda, salt, and cocoa powder. This helps the dry ingredients mix evenly, giving your cookies a smooth, fudgy texture once baked.
I use this fine mesh strainer, which works really great here and breaks up any lumps in the cocoa powder.
Cream the Butter and Sugar
In a large mixing bowl, cream the butter and sugar for about 4 minutes, or until it’s light and fluffy. The mixture should look pale and creamy before moving on.
A hand mixer makes quick work of this step without tiring your arms.

Add the Wet Ingredients
Beat in the eggs and vanilla extract until the mixture is silky and smooth. This is where you create that rich, chocolate cookie base that holds the marshmallow swirls perfectly.
Combine the Mixtures
Add the sifted dry ingredients to the wet mixture. Fold the dough gently, just until everything comes together. Overmixing can make the cookies dense instead of tender, so stir just until combined to keep the cookies soft and chewy.
Melt and Swirl the Marshmallows
In a small pot, melt the marshmallows gently until smooth and creamy, reserving a few for topping later. Keep the heat low and use a heavy-bottomed saucepan like this one to prevent the marshmallows from scorching.
Pour about a quarter of the melted marshmallows into the dough and give it a few gentle folds to create its signature swirls. Don’t overmix, or the white marshmallow streaks in the chocolate dough will fade away.
Adding in small portions also helps avoid clumping, so don’t pour all the melted marshmallows at once.
Scoop and Air Fry
Scoop portions of dough with a cookie scoop or an ice cream scoop with a trigger release and place them in the air fryer basket lined with parchment paper for easy cleanup. Leave some space between each cookie so they don’t stick and they bake evenly.
Add a small piece of the reserved marshmallow on top for a toasty, gooey finish. Air fry at 325°F (160°C) for 10 minutes, or until the edges are set and the centers still look soft.
Cool and Serve
Transfer the cookies to a wire rack to cool for a few minutes; this helps the texture set while keeping the centers fudgy. Letting them rest a bit also allows the edges to firm up and the centers to set, so they stay intact when you lift them from the basket.
Once cooled slightly, serve them warm with a drink or store them for later. Enjoy!
If you’re bringing these to a holiday gathering or potluck, use a hard-sided container to protect the cookies from getting crushed in transit. Then, I tuck that into an insulated carrier to keep them warm and gooey until you’re ready to serve.

Notes
- Measure precisely: Level off your flour and cocoa powder so the dough doesn’t get too dry or sticky.
- Use room temperature ingredients: Make sure your butter and eggs are at room temperature before mixing. They blend more evenly with sugar and cocoa, giving your cookies a soft, tender crumb that pairs perfectly with marshmallow fluff or vegan marshmallows.
- Add flavor boosters: Mix in chopped white chocolate, pieces of milk chocolate bar, or chocolate melt for creamy pockets of melty chocolate throughout the dough.
- Create s’mores-inspired texture: Press graham cracker halves under each cookie for crunch, spread a thin layer of marshmallow fluff between the dough and cracker for a gooey center, or fold in chopped peanut butter cups for a salty-sweet, classic s’mores-style cookie.
- Adjust for sweetness balance: If using darker chocolate or swapping in vegan marshmallows, add about two tablespoons more sugar to maintain the same level of sweetness and softness.
- Preheat your air fryer: Warm the air fryer for 3–5 minutes before baking so the cookies cook evenly and the marshmallow swirls hold their shape beautifully.
- Store and reheat properly: Keep cooled cookies in an airtight container at room temperature for up to 5 days, in the fridge for up to a week, or freeze for up to 2 months to keep them fresh and chewy. Reheat in the air fryer or microwave until warm and slightly soft in the center.

How to Store Leftovers
Once the cookies have cooled completely, store them in an airtight container at room temperature for up to 5 days. To extend their freshness, refrigerate them for up to a week; they’ll stay chewy and rich.
I like using these airtight glass containers to seal in the cookies’ softness and prevent them from drying out.
To freeze, arrange the cooled cookies in a single layer on a freezer-safe baking sheet, then freeze until solid and transfer to a freezer bag. They’ll keep for about 2 months. Reheat briefly in the air fryer or microwave until warm and slightly soft in the center.
What to Serve With Air Fryer Marshmallow Swirl Cookies
These cookies are delightful on their own, but they’re even better with a cold glass of milk or a cozy cup of coffee. I also love serving them slightly warm with a scoop of vanilla ice cream for an extra decadent, comforting finish.
