Chocolate marshmallow cookies are fudgy, brownie-like cookies with a hint of espresso and a gooey marshmallow center! These marshmallow-stuffed cookies are easy to make in one bowl with simple ingredients.
A chocolate and marshmallow combination is classic! I used my chocolate Snickerdoodles as the base for this recipe and they turned out perfect.
While most chocolate marshmallow cookies require no chill time, as a pastry chef I've learned that chilling the dough enhances flavor and texture. They are worth the wait, making this recipe the best!
why you'll love these chocolate marshmallow cookies

ingredient notes & substitutions
Light brown sugar: You can substitute dark brown sugar if needed.
Cocoa powder: These chocolate marshmallow cookies are made with Dutch-processed cocoa powder, for the richest chocolate flavor. I don't recommend substituting it with natural cocoa powder.
Espresso powder: Espresso intensifies chocolate (try my espresso cookies!). It's the key ingredient for elevating the cookie's flavor. Use espresso powder, not instant coffee or grounds, for maximum coffee taste. Skip it if you're not a fan!
Regular marshmallows: You will need large marshmallows cut in half. You can also use a few mini marshmallows instead. I recommend Jet-Puffed Marshmallows for the best results.

These chocolate marshmallow cookies are meant to shine with just marshmallows. However, you can add dark chocolate chips, milk chocolate chips, or white chocolate chips.
Line a baking sheet with parchment paper and set it aside.
Step 1: Cream the butter and sugars. In a large mixing bowl or the bowl of a stand mixer, cream the room-temperature butter, brown sugar, and white sugar until light and fluffy.
Step 2: Mix in the wet ingredients. Then mix in the egg, egg yolk, and vanilla extract and mix until just combined.
Step 3: Mix in the dry ingredients. Mix in the flour mixture until just combined. Do not overmix!
Cover the bowl with plastic wrap and chill the cookie dough in the fridge for 30 minutes.
Step 4: Scoop and stuff with marshmallows. Scoop the chocolate cookie dough into 2-tablespoon balls (standard cookie scoop).
Flatten it some, then place the marshmallow half (on its side) in the center and mold the dough around it so it's completely encased.
Step 5: Roll in sugar. Roll each cookie dough ball in coarse sugar and place them on the baking tray.
To ensure they have crinkle tops, make sure the top of the cookie has a pile of sugar on top of it (seen in the next photo).
Step 6: Bake! Bake the cookies spaced 2-3 inches apart for 8-10 minutes.
They're done when the puffy top cracks and edges are set.
Cool on a wire rack before removing. You may need to use a spatula to remove them if the marshmallow is sticking to the bottoms!
expert baking tips
Use a kitchen scale. Baking with a scale is much more accurate than cup measurements. To convert this recipe, click the "metric" button next to the ingredients title on the recipe card. If you do not have a scale, use a spoon to fluff the flour first, then spoon it into your measuring cup.
Check your butter temperature. The ideal temperature for cookie dough is around 65 to 68 F, where it's cool to touch, but your finger can leave an indent.
Put the marshmallow on its side. Once cut, the marshmallow should be placed on its side, not flat (don't put it cut side down). This will keep the marshmallow from oozing out.
storage & freezing
Store any baked marshmallow cookies in an airtight container for 1-2 days at room temperature.
You can keep the cookie dough in the fridge for up to 3 hours before baking if needed.
It's hard to tell when they're done as they won't brown. Look for puffy cookies with cracked tops. They'll bake more on the hot tray after baking, resulting in a soft, chewy texture after cooling.
After testing, I found that the marshmallow tends to melt more into the cookie due to the longer bake time. It's totally possible, but just know you may not have as much of a gooey marshmallow in the center!
Yes! I recommend using at least 3 mini marshmallows.
You can, but marshmallow fluff is messier and harder to stuff into cookies. I recommend freezing the fluff first so that it's easier to work with. Spray your hands with non-stick spray and then roll the fluff into balls before stuffing them into the dough.
