The first cold night of December, I always make a pot of cocoa. The second cold night, I make hot chocolate cookies, because a cookie is easier to hand out to neighbors than a mug. These are thick, soft, and deeply chocolatey, with crackly tops and a marshmallow hiding in the middle.
The secret is a couple of packets of hot cocoa mix stirred right into the dough. It brings that milky, nostalgic cocoa flavor you cannot get from cocoa powder alone. Then each ball of dough gets wrapped around a big marshmallow, so when you break one open warm, you get that gooey stretch everyone loves.
These cookies are perfect next to a mug of creamy French hot chocolate or a peppermint hot chocolate. For a full holiday cookie tray, add my chocolate peppermint cookies and gingerbread kiss cookies.

Why You’ll Love These Hot Chocolate Cookies
They taste like Christmas morning cocoa, but you can eat them with one hand.
Gooey Marshmallow Center
Every cookie hides a soft, melty marshmallow that stretches when you break it.
Real Cocoa Flavor
Hot cocoa mix gives a creamy, milk-chocolate taste that pure cocoa powder misses.
Thick and Fudgy
Brown sugar, melted butter, and a short chill make soft, chewy centers.
Great for Gifting
They stay soft for days and look adorable in a cookie tin.
Kid-Approved Baking
Wrapping dough around marshmallows is a fun job for little bakers.
What Are Hot Chocolate Cookies?
Hot chocolate cookies are chocolate cookies flavored with hot cocoa mix and cocoa powder so they taste like a mug of hot chocolate. Most versions include a marshmallow, either baked into the center or pressed on top at the end.
This version does both styles in one recipe: a large marshmallow is sealed inside the dough, and you can press a marshmallow half on top in the last minutes of baking for a toasted look.

Ingredient Tips
Pick a Milk Chocolate Cocoa Mix
Classic milk chocolate cocoa mix works best. Skip mixes with built-in mini marshmallows, as they melt into sticky spots.
Freeze the Marshmallows
Frozen marshmallows melt more slowly, so they stay gooey instead of leaking out.
Let the Butter Cool
Hot butter can scramble the egg and make the dough greasy. Warm is fine.
Use Chunks, Not Just Chips
Chopped chocolate bars melt into bigger puddles than chips.
Spoon and Level the Flour
Packing flour into the cup makes dry, cakey cookies.
How to Make Hot Chocolate Cookies
Step 1: Freeze the Marshmallows
Place the large marshmallows on a plate and freeze for at least 30 minutes while you make the dough.
Step 2: Mix the Dry Ingredients
Whisk the flour, cocoa powder, hot cocoa mix, baking soda, and salt in a medium bowl.
Step 3: Mix the Wet Ingredients
In a large bowl, whisk the melted butter with both sugars until glossy. Whisk in the egg, yolk, and vanilla.
Step 4: Make the Dough
Fold the dry ingredients into the wet until just combined, then stir in the chocolate chunks. Cover and chill the dough for 30 minutes so it is easy to wrap.
Step 5: Stuff the Cookies
Heat the oven to 350°F. Scoop about 2 tablespoons of dough, flatten it in your palm, set a frozen marshmallow in the middle, and wrap the dough around it. Roll into a ball, making sure the marshmallow is fully sealed.
Step 6: Bake
Place 8 balls on each lined sheet, at least 3 inches apart. Bake for 10 to 12 minutes, until the edges are set and the centers look slightly underdone. Press a marshmallow half on top for the last 2 minutes if you like.
Step 7: Cool
Let the cookies rest on the pan for 10 minutes before moving them to a rack. Sprinkle with flaky salt while warm.
Expert Tips for Perfect Hot Chocolate Cookies
Seal Every Seam
Any gap lets the marshmallow escape and caramelize on the pan. Pinch the dough closed tightly.
Do Not Overbake
Pull them when the middles still look soft. They firm up as they cool.
Scoot the Edges
Right out of the oven, use a round cutter to nudge each cookie into a perfect circle.
Bake One Tray at a Time
The middle rack gives the most even heat for thick cookies.
Warm Before Serving
Ten seconds in the microwave brings back the gooey center on day two.
Delicious Variations
Peppermint Hot Chocolate Cookies
Add ½ teaspoon peppermint extract and top with crushed candy canes.
Mexican Hot Chocolate Cookies
Add 1 teaspoon cinnamon and a pinch of cayenne to the dry ingredients.
Nutella Center
Swap the marshmallow for a frozen teaspoon of Nutella.
White Chocolate Snow
Use white chocolate chunks for a snowy look against the dark dough.
Salted Caramel Cocoa
Tuck a soft caramel square next to the marshmallow.
What to Serve with Hot Chocolate Cookies
Serve them warm with cold milk, coffee, or a mug of cocoa. They also look festive on a cookie board with gingerbread men cookies and Christmas candy bark.
For gifting, stack four cookies in a cellophane bag with a packet of cocoa mix and tie it with ribbon.
Storage Instructions
| Storage Method | How Long | Best Practice |
|---|---|---|
| Room Temperature | 4 days | Airtight container with a slice of bread to keep them soft |
| Freezer (baked) | Up to 2 months | Layered between parchment in a freezer bag |
| Freezer (dough balls) | Up to 3 months | Stuffed and frozen solid, then bagged |
Store cooled cookies in an airtight tin. The marshmallow firms up as it sits, so warm a cookie for 10 to 15 seconds before eating.
Bake frozen stuffed dough balls straight from the freezer, adding 1 to 2 minutes to the bake time.
Can You Make It Ahead?
Yes. The dough keeps covered in the fridge for up to 2 days. Let it soften for 10 minutes before wrapping it around the marshmallows.
For holiday baking marathons, stuff and freeze the dough balls weeks ahead so you can bake fresh cookies whenever guests show up.
Common Mistakes to Avoid
Using Room-Temperature Marshmallows
They melt too fast and burst through the dough.
Leaving Gaps in the Dough
The marshmallow leaks and burns onto the pan.
Skipping the Chill
Warm dough spreads thin and is hard to wrap.
Crowding the Pan
These cookies spread, so give them 3 inches of space.
Baking Until Firm
Fully firm cookies turn dry and crumbly once cool.

Frequently Asked Questions
Why did my marshmallow leak out of the cookies?
The dough was not fully sealed or the marshmallow was too warm. Freeze the marshmallows and pinch the seams closed before baking.
Can I use hot cocoa mix instead of cocoa powder?
This recipe uses both. Hot cocoa mix gives the milky cocoa flavor, while cocoa powder adds deep chocolate color and structure.
How do I keep hot chocolate cookies soft?
Slightly underbake them and store them airtight with a slice of bread, which keeps them moist.
Can I freeze the dough?
Yes. Stuff the marshmallows, freeze the dough balls on a tray, then bag them. Bake from frozen with an extra minute or two.
Do I have to stuff the marshmallows?
No. You can bake the cookies plain and press marshmallow halves on top for the last 2 minutes instead.
Conclusion
These hot chocolate cookies are everything I want in a winter cookie: thick, fudgy, a little gooey, and full of cozy cocoa flavor.
Freeze those marshmallows, seal the dough tight, and pull them out while the centers are still soft. Then pour a mug of cocoa and enjoy one warm.
