Marshmallow stuffed funfetti cookies are an air fryer treat built on half a graham cracker layered with funfetti frosting, rainbow sprinkles, and a jumbo marshmallow, then wrapped in Pillsbury Birthday Cake cookie dough and air fried at 350F for about 12 minutes. The graham base keeps the bottom sturdy while the marshmallow melts into a gooey, pull-apart center.
My freezer pretty much always has a tube of cookie dough in it for exactly these kinds of nights, the ones where I want something warm and a little ridiculous without dragging out the stand mixer. This is the cookie I reach for when a normal cookie feels too, well, normal.
It started as a what-if: what if I tucked a whole s’more inside a funfetti cookie? Now it might be the only cookie I make on repeat. One bite gives you crunchy graham, gooey marshmallow, sweet vanilla frosting, and soft birthday-cake cookie all at once. If you love a fun, easy dessert hack, it lands in the same lane as my strawberry s’mores and my gooey ghost s’mores dip.
What makes these marshmallow stuffed funfetti cookies so good
It is all about the layers. The graham cracker on the bottom stays crisp and gives every cookie a little structure, so it never goes flat or greasy. Above that, the frosting and sprinkles melt into the dough for pure birthday-cake flavor, and the jumbo marshmallow puffs up and turns into a stretchy, toasty center.
Using Pillsbury Birthday Cake cookie dough is the shortcut that makes this a 20-minute project. The confetti sprinkles are already baked into the dough, so you get that funfetti look and vanilla-cake taste without measuring a single thing.
Can you put marshmallows in the air fryer?
Yes, as long as you tuck the marshmallow inside the dough instead of leaving it exposed on top. A bare marshmallow in the air fryer will scorch and stick to the basket fast because the circulating heat hits it directly. Sealing it inside three balls of cookie dough lets it melt low and slow into a gooey center while the cookie around it bakes. If a little does peek out and toast, that’s the best bite, so don’t panic.
What temperature do you air fry cookies at?
Air fry these at 350F for about 12 minutes, until the tops are set and lightly golden. Air fryers run hotter and faster than ovens, so 350F gives the inside time to cook before the outside gets too dark. Check the first batch at the 10-minute mark, since every air fryer is a little different. For more on the method, The Kitchn has a solid primer on baking cookies in an air fryer.
Tips for the best funfetti marshmallow cookies
Seal the dough all the way around
Press the dough disk down over the marshmallow and pinch it closed against the graham cracker. A good seal keeps the marshmallow from leaking out and welding itself to your basket as it melts.
Use three dough balls per cookie
Three squished-together balls give you enough dough to fully wrap a jumbo marshmallow. Two leaves the dough too thin, and the marshmallow will burst through the top.
Do not skip the graham cracker base
The graham cracker isn’t just for s’mores flavor. It acts as a sturdy little platform so the bottom of the cookie doesn’t spread or stick, the same trick that keeps my Biscoff marshmallow treats holding their shape.
Let the first batch be your test
Air fryer wattage varies a lot. Pull the first cookie at 12 minutes, see how set it is, and adjust the time up or down by a minute for the rest.
Cool before you lift
Give the cookies about 5 minutes after they come out. Straight from the basket the marshmallow center is molten and will run if you move them too soon.
Storage and leftovers
These are at their absolute best warm and fresh, when the marshmallow is still gooey. If you have extras, store them in an airtight container at room temperature for up to 3 days. To bring back that just-made center, pop one in the air fryer at 320F for 2 to 3 minutes, or microwave it for about 10 seconds.
For another warm, gooey cookie situation that is built for sharing, my pizookie recipe bakes a giant skillet cookie until the edges are set and the center is still soft, then you top it with ice cream and eat it straight from the pan.
You can also build the cookies ahead and air fry to order, which is clutch for parties. Think of it like my rice krispies treats roundup: easy, make-ahead, crowd-pleasing sweets that disappear fast.
Equipment
Ingredients
This makes 4 big cookies. Scale it up or down by ones, since every cookie is built the same way.
- 2 graham crackers, broken in half (4 halves total)
- 1/4 cup Pillsbury Funfetti Frosting
- 2 tsp rainbow sprinkles
- 4 jumbo marshmallows
- 12 balls Pillsbury Birthday Cake Cookie Dough (3 per cookie)
No Birthday Cake dough at your store? Any refrigerated sugar cookie dough works, and you can stir a teaspoon of sprinkles into each portion to fake the funfetti look. For a deeper s’mores hit, swap the funfetti frosting for chocolate frosting or a square of melting chocolate. If you would rather bake than air fry, this also works on a lined sheet pan, the same way I make my cornbread cookies.
Instructions
- Break each graham cracker in half. On one half, spread about 1 tbsp funfetti frosting, scatter a pinch of rainbow sprinkles, and press a jumbo marshmallow on top.
- Squish 3 cookie dough balls together and flatten them into a thin disk a bit wider than the marshmallow. Drape it over the marshmallow and press the edges down around the graham cracker to seal it shut.
- Set the cookies on a piece of parchment in the air fryer basket, leaving space between them. Air fry at 350F for about 12 minutes, until the tops are set and lightly golden.
- Let them rest for 5 minutes so the marshmallow stops bubbling and the cookie firms up, then enjoy them warm.
If air fryer desserts are your thing, try the viral rice paper croissant next, it is another quick sweet fix from the basket. And Pillsbury keeps a running list of Birthday Cake cookie dough info if you want to read up on the dough itself.

Instructions
- Build the base. Break each graham cracker in half. On one half, spread about 1 tbsp funfetti frosting, scatter a pinch of rainbow sprinkles, and press a jumbo marshmallow on top.
- Wrap in dough. Squish 3 cookie dough balls together and flatten into a thin disk a bit wider than the marshmallow. Drape it over the marshmallow and press the edges down around the graham cracker to seal.
- Air fry. Set the cookies on parchment in the air fryer basket with space between them. Air fry at 350F for about 12 minutes, until set and lightly golden.
- Cool and serve. Rest 5 minutes so the marshmallow center sets up slightly, then enjoy warm.
Notes
- Seal the dough well around the marshmallow so it does not leak out and stick to the basket as it melts.
- Three dough balls per cookie fully wraps a jumbo marshmallow; two leaves it too thin.
- Air fryers run hot and fast, so check at 10 minutes the first time and adjust.
- Parchment keeps the bottoms from sticking and makes cleanup easy. Leave room for air to circulate.
- Let the cookies cool 5 minutes before lifting or the molten centers will spill.
