I make these chocolate marshmallow swirl cookies whenever I need something impressive but easy. The rich chocolate base is perfectly fudgy, while the marshmallow creates beautiful swirls and pockets of gooey sweetness throughout each cookie.
What makes me especially excited about this recipe is the texture contrast – crispy edges with soft, chewy centers and melty marshmallow pockets. They’re like eating a campfire s’more in cookie form!
Ingredients You’ll Need
For the Chocolate Base
-
1¾ cups all-purpose flour
-
½ cup unsweetened cocoa powder
-
1 teaspoon baking soda
-
½ teaspoon salt
-
1 cup butter, softened
-
¾ cup brown sugar, packed
-
½ cup granulated sugar
-
2 large eggs, room temperature
-
1 teaspoon vanilla extract
-
1 cup mini chocolate chips (optional)
For the Marshmallow Swirl
-
1½ cups mini marshmallows
-
¼ cup marshmallow fluff
-
1 tablespoon powdered sugar (for dusting)
Step-by-Step Instructions
Making the Chocolate Dough
I preheat my oven to 350°F and line baking sheets with parchment paper. In a medium bowl, I whisk together flour, cocoa powder, baking soda, and salt.
In a large bowl, I cream the softened butter with both sugars until light and fluffy (about 3 minutes). Then I beat in eggs one at a time, followed by vanilla extract.
I gradually mix the dry ingredients into the wet ingredients until just combined, being careful not to overmix. If using chocolate chips, I fold them in now.
Creating the Swirl
Here’s where the magic happens! I lightly dust mini marshmallows with powdered sugar to prevent sticking. I scoop about 2 tablespoons of dough and flatten it slightly. I press 4-5 mini marshmallows into the center, add a small dollop of marshmallow fluff on top, then cover with a pinch more dough.
I gently roll it into a ball and use a toothpick to swirl the marshmallow fluff on top, creating that beautiful marbled effect.
Baking to Perfection
I place cookies 2 inches apart on the baking sheets and bake for 10-12 minutes until edges are set but centers still look slightly soft. The cookies will continue to firm up as they cool.
I let them cool on the pan for 5 minutes before transferring to a wire rack. This prevents the marshmallow from becoming too sticky.
Serving Suggestions
These cookies are amazing on their own, but I love serving them slightly warm with a cold glass of milk. For an extra indulgent treat, I sandwich vanilla ice cream between two cookies for the ultimate marshmallow cookie ice cream sandwich!
Tips for Customization
For extra flavor, I sometimes add a teaspoon of espresso powder to intensify the chocolate taste. Adding crushed graham crackers to the dough creates a true s’mores experience. White chocolate chips instead of regular chocolate chips offer a sweeter twist.

Frequently Asked Questions
How do I prevent the marshmallow from leaking out?
Make sure to completely seal the dough around the marshmallows and don’t overfill. Dusting marshmallows with powdered sugar also helps them stay in place.
Can I use regular marshmallows instead of mini?
Yes, but mini marshmallows work better because they distribute more evenly throughout the cookie. If using regular, cut them into smaller pieces.
Why are my cookies spreading too much?
Make sure your butter is softened but not melted, and don’t skip the cooling time. You can also chill the dough for 15 minutes before baking to reduce spreading.
Can I freeze the cookie dough?
Absolutely! Shape the cookies, freeze them on a baking sheet, then transfer to a freezer bag. Bake directly from frozen, adding 1-2 extra minutes to baking time.
These chocolate marshmallow swirl cookies have become my go-to recipe for parties, bake sales, and whenever I need a chocolate fix! The combination of fudgy chocolate and gooey marshmallow is absolutely irresistible. Give them a try and watch them become your new favorite cookie!
