Chocolate Marshmallow Cookies feature tender, caky, peppermint chocolate cookies with a marshmallow hidden under a fudgy homemade chocolate frosting.
Every year around the holidays, you’ll find festive peppermint swirl marshmallows. They are so fun and pretty with their pink swirls that I can’t resist buying a bag or two. Years ago, I started adding them to my classic Marshmallow Surprise Cookie recipe for a seasonal twist. You can’t go wrong with the classic combination of chocolate and peppermint with a colorful surprise inside.
Update: I’ve updated this post with new photos and tips so you and your loved ones can enjoy these pillowy peppermint chocolate marshmallow cookies this holiday season.
How to Make Chocolate Marshmallow Cookies
There are three layers to these Christmas cookies. First, a fudgy, cake-like chocolate cookie on the bottom. Then, the surprise layer of a fluffy peppermint marshmallow. And finally, a smear of fudgy homemade chocolate frosting. As a result, every bite of homemade cookie has the perfect balance of texture, sweetness, and seasonal flair.
Despite these three beautiful layers, these cookies are impressively easy to make. The frosting comes together in one bowl with five simple ingredients.
What Kind of Marshmallows Should I Use?
These chocolate marshmallow cookies will work with most seasonal marshmallows. I usually find fun holiday marshmallows at Target or Walmart, or wherever Jet-Puffed marshmallows are sold.
If you can’t find colorful or flavored marshmallows, you can also use plain jumbo ones. The jumbo ones are better, as you’ll slice each marshmallow into two rounds. Even with plain marshmallows, you’ll have a seasonal touch of peppermint flavor from the extract in the cookie dough.
This year Kraft only sold the peppermint swirl mini marshmallows, which will work as well, just put a few minis on top of the cookie instead of half of a jumbo marshmallow.
Or, if you’re feeling ambitious, one of our readers found a homemade marshmallow recipe to make these cookies 100% from scratch!
Tip: When baking cookies, use a scoop to portion out the dough and get perfectly round, even size cookies.
How Will I Know the Cookies are Done?
With chocolate cookies, it can be trickier to know when they’re done baking. You won’t see the same golden color cues as you get from sugar or chocolate chip cookies. And with this recipe, you want to be sure not to over-bake the cookies the first time around.
Remember, you’ll be putting the cookies back into the oven for another 2 to 3 minutes with a marshmallow slice on top. I recommend pulling them when the edges are set and the center has started to firm up. I err on the side of less cooking and usually remove them after 7 minutes.
