Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

All-purpose flour
Unsweetened cocoa powder
Baking soda
Salt
Unsalted butter
Granulated sugar
Brown sugar
Eggs
Vanilla extract
Mini marshmallows or marshmallow fluff
Semi-sweet chocolate chips

Directions

I start by preheating my oven to 350°F (175°C) and lining a baking sheet with parchment paper.
In a medium bowl, I whisk together flour, cocoa powder, baking soda, and salt.
In a large bowl, I cream the butter, granulated sugar, and brown sugar until light and fluffy.
I beat in the eggs one at a time, followed by the vanilla extract.
Gradually, I add the dry ingredients to the wet, mixing just until combined.
I fold in the chocolate chips and then gently swirl in the mini marshmallows or spoonfuls of marshmallow fluff. I try not to overmix so the swirl effect stays visible.
Using a cookie scoop, I drop spoonfuls of dough onto the baking sheet, spacing them about 2 inches apart.
I bake for 9–11 minutes, just until the edges are set and the centers still look soft.
Once out of the oven, I let them cool on the pan for 5 minutes before transferring to a wire rack.

Servings and timing

This recipe makes about 24 cookies. It takes roughly 15 minutes to prep and 10 minutes to bake. Cooling time adds another 10–15 minutes. So, in about 35–40 minutes, I’ve got a fresh batch of gooey chocolate-marshmallow heaven.

Variations

Sometimes I like to change things up by adding chopped nuts like walnuts or pecans for crunch. If I’m in a festive mood, I’ll use peppermint marshmallows or stir in a little peppermint extract. I’ve also tried replacing the chocolate chips with white chocolate chunks—it gives the cookies a whole new flavor twist that I love.

storage/reheating

I store these cookies in an airtight container at room temperature for up to 5 days. To keep the marshmallow soft and gooey, I sometimes reheat one or two in the microwave for 10–15 seconds. If I make a big batch, I freeze the dough balls and bake fresh cookies as needed. Chocolate Marshmallow Swirl Cookies

FAQs

How do I keep the marshmallows from melting too much?

I usually use mini marshmallows and gently fold them into the dough without overmixing. Chilling the dough for 15 minutes before baking can also help keep them intact.

Can I use marshmallow fluff instead of mini marshmallows?

Yes, I often swirl in marshmallow fluff for a smoother texture and more even distribution. It melts beautifully and gives a nice gooey swirl.

Why are my cookies spreading too much?

If my cookies spread too much, it’s often because the butter was too soft or the dough was too warm. I pop the dough in the fridge for 15–20 minutes to help control spreading.

Can I make the dough ahead of time?

Definitely. I make the dough, scoop it into balls, and refrigerate for up to 3 days or freeze for up to 2 months. When I bake from frozen, I just add an extra minute or two to the bake time.

Are these cookies good for gifting?

Absolutely. I love packaging these cookies in clear treat bags or cookie tins. They look beautiful with the marshmallow swirls and hold up well for shipping if kept in a cool environment.

Conclusion

Chocolate Marshmallow Swirl Cookies are everything I want in a treat—rich, chewy, and just the right amount of gooey. They’re simple to make but look impressive, and they always bring a smile to anyone who tries them. Whether I’m baking for a special occasion or just because, these cookies never disappoint.
