Chocolate Marshmallow Swirl Cookies bring together rich cocoa with that classic gooey marshmallow vibe we all love. These have crinkly, eye-catching tops and soft insides that’ll stand out on a party platter or during a lazy Sunday on the couch.
The first time I made these was for a class event at my kid’s school Now my relatives ask for them at every get-together Swirling the marshmallow always puts a smile on my face every single time
Irresistible Ingredients
- Marshmallow fluff: packs in that ooey-gooey middle and makes gorgeous swirls For the best streaks give the fluff a good mix before adding it
- Vanilla extract: ties all the flavors together with a cozy mellow note Real vanilla is definitely worth using if you’ve got it
- Large eggs: help hold the dough together and keep cookies soft Let them sit at room temp so everything blends smoothly
- Granulated sugar: gives you just the right crispness at the edges and the sweet contrast to the chocolate Try superfine for an even lighter crumb
- Unsalted butter: sneaks richness into every bite Leave it out so it softens up for easy mixing
- Salt: makes the chocolate really pop and keeps things from leaning too sweet Go with fine sea salt so it blends evenly
- Baking soda: keeps your cookies from falling flat Make sure yours is fresh for best puffiness
- Unsweetened cocoa powder: is the secret to deep chocolate cookies Dutch process is especially nice if you love a smooth chocolate taste
- All-purpose flour: gives that perfect cookie texture Just scoop then level off for accuracy
Simple How-To
- Cool on Pan:
- Once out of the oven let cookies hang out on the tray for five minutes before moving to a rack This gives the marshmallow a chance to set up so nothing sticks
- Bake:
- Bake for about ten to twelve minutes You want the edges just set but middles still a little gooey Toss on a spoonful more fluff halfway through if you crave extra goo
- Form Cookies:
- Scoop dough into balls and drop onto lined trays Make a small dip in each and dollop in marshmallow fluff Swirl it with a toothpick for that cool marbled design
- Preheat Oven:
- Turn your oven on to 350 degrees Fahrenheit Line your baking sheets with parchment for easy cleanup and even baking
- Chill the Dough:
- Cover the mixing bowl and chill for at least an hour You want the dough nice and firm so cookies don’t spread like crazy when baking
- Swirl in Marshmallow:
- With a spatula fold marshmallow fluff through the dough Just give it a couple gentle turns so pretty ribbons pop through
- Combine Wet and Dry:
- Pour your dry mix in with the creamed butter mixture Stir just until no flour streaks are left Over-mixing will make your cookies tough
- Add Eggs and Vanilla:
- Mix in eggs one after the other Make sure each one’s blended before the next Add that splash of vanilla for a little extra warmth
- Cream Butter and Sugar:
- Beat sugar with your softened butter till it’s pale and fluffy A hand mixer works great and three or four minutes usually nails it
- Mix Dry Ingredients:
- In another bowl whisk your flour cocoa baking soda and salt so everything’s well combined This’ll make sure you don’t get any bitter bites

Every time I make these my favorite part is swirling in marshmallow and watching those one-of-a-kind patterns show up My youngest always takes marshmallow duty and somehow adds a little extra in each cookie
Smart Storage
After the cookies cool off toss them in an airtight container or tin They’ll stay tasty and soft for as long as five days on the counter Got extra Freeze them with parchment between layers They’ll be good for a month If you want fresh baked cookies whenever freeze the dough balls You can bake straight from the freezer Just let them go a couple more minutes in the oven
Swap It Up
No marshmallow fluff left Just melt mini marshmallows and swirl them in It works fine If you’re crazy for chocolate throw in a few chocolate chips Want more cocoa flavor Pick a Dutch processed one Out of butter High-end baking margarine is fine but the taste won’t be quite as rich
How to Serve
These go great solo but are awesome for turning into ice cream sandwiches Stack chocolate or vanilla ice cream in between Keep the fun going by piling them on a tray with other favorites like ginger snaps or peanut butter cookies Toss a couple into a lunch bag for a sweet midday treat

FAQs About the Recipe
- → How can I get the marshmallow to swirl just right?
Pop a bit of fluff on the middle of each dough ball, then drag a toothpick through it. Give it a light swirl before they hit the oven.
- → Is it okay to swap in real marshmallows?
Go for it—melted or giant ones work. Your cookies will come out with a different texture and look, but they'll still taste great.

Chilled dough doesn’t spread as much, flavors blend better, and working with it is way less messy.

Yep! Roll up the dough balls and freeze 'em. When you want cookies, bake straight from the freezer—just give them a little extra time.

It’s that pure unsweetened cocoa and spot-on sugar balance. You get a lot of bold chocolate flavor and just enough sweetness.
