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.

→ What’s the reason for chilling this dough?

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

→ Can I freeze unbaked cookie dough?

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.

→ What makes these so chocolatey?

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

→ What’s the best way to keep these fresh after baking?

Once they cool, stash them in something airtight and keep at room temp. That keeps them soft and yummy for days.

Step-by-Step Guide

Step 01

Let the cookies chill out on the pan for five minutes before moving them to a rack. Give them time to finish cooling for the best chewy results.

Step 02

Slide the baking tray in the hot oven. Let them bake around 10–12 minutes so edges firm up but centers stay squishy. Toss a little more fluff on top halfway if you want them super gooey.

Step 03

Scoop balls of cold dough—tablespoon or small scoop works. Spread them out on the lined trays so they don’t touch. Poke a little hollow in each ball. Drop in marshmallow spread. Give it a swirl with a toothpick if you like.

Step 04

Fire up your oven to 350°F (175°C) about twenty minutes out. Set up two trays with parchment or silicone mats so nothing sticks.

Step 05

Cover the dough and tuck it in the fridge for at least an hour. It’ll be way easier to shape and won’t spread as much in the oven.

Step 06

Gently fold marshmallow fluff through the dough with a spatula for streaks. Want big marshmallow pockets? Wait and swirl it in later after chilling.

Step 07

On low, slowly work in the dry blend with the wet stuff. Stop mixing when you’ve just got a dough—don't keep going or you’ll get tough cookies.

Step 08

Beat in the eggs, one after the other. Each time, let them mix in before tossing in the next. Pour in the vanilla and stir until it all comes together.

Step 09

Put soft butter and sugar in a big bowl. Mix with a hand mixer for 3–4 minutes. Stop when everything looks thick and creamy.

Step 10

Dump salt, baking soda, cocoa powder, and flour in a medium bowl. Give it a good whisk so it’s all mixed up nicely.

Additional Notes

  1. Extra-sticky dough? Let it chill an extra half hour for less stick and easier shaping.
  2. Swap in some melted marshmallows if you want bold swirls instead of regular fluff.
  3. Tuck a big marshmallow in the middle for a gooier filling.
  4. Spin your trays front to back halfway through baking so they bake even and get nice color.
  5. Keep your cookies in a sealed container at room temp so they stay fresh and soft.
  6. Freeze dough balls for later—they bake great straight from the freezer. Just tack on a minute or two.
