These chocolate cookies with marshmallow swirls turn basic kitchen staples into an indulgent snack that combines deep cocoa flavor with soft, gooey marshmallow bits. The eye-catching spiral pattern makes them look as good as they taste, ideal for wowing friends or treating yourself to something sweet.
I whipped these up for my kid's school fundraiser, and they were gone in seconds. They've now become our family's go-to treat that everyone in the neighborhood keeps asking us how to make.
Ingredients
Step-by-Step Instructions

The marshmallow bits in these cookies always take me back to summer bonfires and making s'mores. I once baked a batch for our family get-together where my grandma said they topped the chocolate cookies she'd been making for six decades. That's when I knew this recipe would stick around in our family.

Common Questions
- → How do I keep my cookies from flattening out too much?
Make sure you pop the dough in the fridge for at least an hour before you bake them so they'll stay nice and puffy.
- → Can I swap in normal marshmallows instead of fluff?
Sure thing, you can melt down regular marshmallows to swirl in, or stick a big marshmallow right in the middle for extra puffiness.
- → What's the best way to keep leftover cookies?
Pop them in a sealed container at room temp and they'll stay good for about 5 days.
- → Is it okay to freeze the cookie dough?
Absolutely, just roll it into balls first. When you're ready, bake them frozen but add 2 more minutes to your timer.
- → How can I get that pretty marshmallow swirl pattern?
Grab a toothpick and gently drag it through the marshmallow fluff on top of the cookie dough before baking for a cool swirly look.
