Chocolate Marshmallow Swirl Cookies

Featured in Sweet Delights for Every Occasion.

Chocolate marshmallow cookies combine rich, fudgy cookie dough with ribbons of gooey marshmallow fluff for an irresistible treat. The cocoa-based dough has the perfect balance of sweet and bitter notes, while swirls of marshmallow create pockets of sweetness throughout. As they bake, the tops develop a slight crackle while staying soft inside. The marshmallow gets slightly toasted, adding a subtle campfire s'mores flavor that makes these cookies completely addictive. They're perfect with milk and somehow taste even better the next day.

Let me share these incredible Chocolate Marshmallow Swirl Cookies with you! Every time I make them, they bring back memories of cozy winter evenings sipping hot cocoa by the fire. The way those gooey marshmallow ribbons swirl through the rich chocolate dough is pure magic. I discovered this recipe while trying to capture the essence of s'mores in cookie form, and now they're the most requested treat at our family gatherings.

Cozy Comfort in Every Bite

Each cookie is like a little piece of comfort wrapped in chocolate. The rich, tender chocolate base gets even better when those marshmallows melt and create beautiful swirls throughout. What I love most is how they look almost too pretty to eat with those striking white swirls against the dark cookie but once you try one, you won't be able to resist reaching for another!

Kitchen Secrets

Here's what I've learned from countless batches: chill your dough for at least an hour it makes a huge difference in texture. Use a light-colored baking sheet to prevent burning, and rotate the pan halfway through baking for even results. The marshmallow magic happens in the last few minutes, so keep a close eye on them!

Make It Your Own

These cookies are wonderfully adaptable! Try different marshmallow flavors, add chopped nuts, or drizzle with caramel. For a minty twist, add peppermint extract during the holidays. Love dark chocolate? Switch to dark cocoa powder! You can even make them gluten-free by using your favorite cup-for-cup flour blend.

Storage Tips

These cookies stay fresh in an airtight container for up to five days that is, if they last that long! Layer them with parchment paper to prevent sticking. Want to plan ahead? The dough freezes beautifully just scoop onto a tray, freeze solid, then transfer to a freezer bag. Bake straight from frozen, adding an extra minute or two.

Perfect Pairings

These cookies are absolute heaven with a cold glass of milk or hot cup of coffee. For an extra special treat, sandwich slightly warm cookies around a scoop of vanilla ice cream. They're perfect for holiday cookie platters, bake sales, or anytime you need a chocolate-marshmallow fix!

Troubleshooting Tips

Cookies spreading too much? Make sure your butter isn't too soft and your dough is well-chilled. Marshmallows disappearing? Add them later in the baking process. If your cookies are too hard, they might be overbaked remember they continue cooking slightly on the hot pan after coming out of the oven.

Frequently Asked Questions

Ensure dough is well chilled and butter at room temperature when mixing. Don't skip chilling step.
