Hot chocolate cookies are soft, fudgy cocoa cookies topped with melty mini marshmallows, and you can have a batch cooling on the counter in about an hour. Scroll to the recipe card below for the full printable version, or keep reading for every step, tip, and swap you need.
How to Make Hot Chocolate Cookies From Start to Finish
You make hot chocolate cookies by creaming butter with brown and white sugar, stirring in cocoa and hot cocoa mix, chilling the dough for 30 minutes, and baking at 350°F for 10 minutes with the marshmallows added for the last 2.
The whole process takes about 55 minutes, and most of that is hands-off chilling time. Every stage below is written so you can bake the whole recipe from this post alone.
Gather Your Ingredients
You need 1/2 cup (1 stick) of softened unsalted butter, 3/4 cup of packed light brown sugar, and 1/4 cup of granulated sugar. The dry side takes 1 1/4 cups of all-purpose flour, 1/2 cup of unsweetened natural cocoa powder, 1/4 cup of powdered hot cocoa mix, 1/2 teaspoon of baking soda, and 1/2 teaspoon of salt.
You also need 1 large egg, 2 teaspoons of vanilla extract, 1/2 cup of semisweet chocolate chips, and 1 cup of mini marshmallows. Swiss Miss or any classic powdered cocoa mix works well, so measure it by the cup rather than counting packets.
Cream the Butter and Sugars
Start with butter that gives slightly when you press it, which means it is soft but still cool. Beat it with both sugars for 2 minutes until the mixture looks pale and fluffy.
This step traps the air that keeps the cookies tender instead of dense. Scrape down the bowl once halfway through so every bit of butter gets creamed.
Add the Egg and Vanilla
Beat in the egg and the vanilla extract until the mixture looks smooth and glossy. The batter should look like thick, silky frosting at this point.
Mix the Dry Ingredients
Whisk the flour, cocoa powder, hot cocoa mix, baking soda, and salt together in a separate bowl so the cocoa is evenly spread. Add the dry mixture to the butter mixture in two batches and mix on low speed until just combined.
Fold in the chocolate chips with a spatula. The dough will be thick and fudgy, almost like brownie batter that has been turned into dough.
Chill the Dough
Cover the bowl and refrigerate the dough for 30 minutes. This firms up the butter, which keeps the cookies thick and prevents them from spreading into thin wafers on the pan.
Scoop and Bake
Heat the oven to 350°F and line two baking sheets with parchment paper. Scoop the dough with a 2 tablespoon cookie scoop, set the balls 2 inches apart, and bake for 8 minutes.
Add the Marshmallows
Pull the pan from the oven and press about 5 mini marshmallows onto the top of each cookie. Return the pan to the oven for 2 more minutes, just until the marshmallows puff and soften.
Let the cookies cool on the pan for 5 minutes before moving them to a wire rack. They will look slightly underbaked in the center at this point, which is exactly what gives them that fudgy texture.
Tips for Fudgy Hot Chocolate Cookies Every Time
The most common reason cocoa cookies turn out dry is too much flour. Spoon the flour into your measuring cup and level it off with a knife instead of scooping straight from the bag, or weigh out 156 grams if you own a kitchen scale.
Pull the cookies at the 8 minute mark even if the centers look soft. Cocoa dough is dark, so it is hard to judge doneness by color, and the cookies keep setting on the hot pan after they come out.
Use a natural unsweetened cocoa powder such as Hershey’s Natural Unsweetened or Ghirardelli unsweetened cocoa. Natural cocoa is acidic, which reacts with the baking soda to give the cookies lift and a slightly crackly top.
If your marshmallows slide off, press them down gently so they sit in the soft surface of the cookie. A little melted marshmallow stuck to the parchment is normal and peels away easily once the pan cools.
Variations and Substitutions for Hot Chocolate Cookies
Swap the Chocolate Chips
Semisweet chips balance the sweet marshmallows and hot cocoa mix best. Milk chocolate chips make the cookies sweeter and more nostalgic, while dark chocolate chips give a more grown-up cup of cocoa flavor.
White chocolate chips also work if you like a cookies and cream look against the dark dough. Keep the amount at 1/2 cup so the dough stays balanced.
Add a Peppermint Twist
For a winter version, stir 1/4 teaspoon of peppermint extract in with the vanilla. The recipe card below leaves this out, so treat it as an optional add-in.
Use Dutch-Process Cocoa
Dutch-process cocoa makes a darker, smoother cookie with a milder flavor. The cookies will rise slightly less because Dutch-process cocoa is not acidic, but they still bake up soft and fudgy.
Add Some Crunch
Stir in 1/4 cup of chopped pecans or crushed pretzels with the chocolate chips for extra texture. The recipe card below leaves this out, so treat it as an optional add-in.
How to Store, Freeze, and Make Ahead
Store the baked cookies in an airtight container at room temperature for up to 4 days. The marshmallow tops are softest on the first day and turn slightly chewy after that.
You can freeze the baked cookies for up to 3 months. Let them thaw at room temperature for about an hour before serving.
The dough also keeps well, so you can refrigerate it for up to 48 hours before baking. For freezer-ready dough, scoop the balls onto a tray, freeze until firm, and move them to a freezer bag for up to 3 months.
Bake frozen dough balls straight from the freezer at 350°F, adding about 2 minutes to the first bake before you add the marshmallows. There is no need to thaw them first.
If you stack the baked cookies, place a sheet of parchment between the layers so the marshmallow tops do not stick together. Keep the container away from heat and direct sunlight so the chocolate chips stay intact.
What to Serve With Hot Chocolate Cookies
The obvious pairing is a mug of warm milk or a classic cup of hot chocolate, which turns the cookie into a dunker. Cold whole milk is just as good if you want the cookies to taste like a bowl of cocoa cereal.
For a coffee break, pair them with a latte or a plain drip coffee, since the bitterness balances the sweet marshmallow. A few cookies stacked on a plate also make a cozy addition to a holiday cookie platter or a hot chocolate bar.
If you want to dress them up, drizzle melted chocolate over the marshmallow tops or sprinkle on a little crushed peppermint. Add those finishing touches after the cookies have cooled completely so the toppings do not slide off.
These cookies also travel well, which makes them a good choice for bake sales, school parties, and cookie exchanges. Pack them in a single layer with parchment between the rows so the marshmallows stay intact.
The Story Behind Hot Chocolate Cookies
Hot chocolate traces back to the Mesoamerican cacao drinks of the Maya and Aztec peoples, which were later sweetened and served warm in Europe. The American version, made with cocoa powder, sugar, and milk, became a winter staple in homes across the country.
Hot chocolate cookies borrow that same comfort-in-a-cup idea and turn it into something you can hold in one hand. Cocoa powder brings the chocolate depth, the cocoa mix brings the milky sweetness, and the marshmallows complete the picture.
Marshmallows started out as a sweet made from the sap of the marsh mallow plant, which is where the name comes from. Today they are a fixture in every mug of cocoa, so putting them on a cookie feels like a natural next step.

Hot Chocolate Cookies FAQs
Can you use hot cocoa mix instead of cocoa powder?
Not completely. Hot cocoa mix is mostly sugar and powdered milk, so swapping it for all of the cocoa would make the cookies too sweet and much less chocolatey.
The best results come from using both, with cocoa powder for depth and the mix for that milky hot chocolate flavor.
Why did my marshmallows melt into puddles?
Marshmallows added at the start of baking have too much time to melt and spread. Add them after the first 8 minutes and bake for only 2 more, just until they puff and soften.
How long do hot chocolate cookies last?
Stored in an airtight container at room temperature, they stay fresh for up to 4 days. The marshmallow tops are softest on day one.
Can you freeze hot chocolate cookies?
Yes, both ways. Baked cookies freeze for up to 3 months, and scooped dough balls freeze for up to 3 months and bake straight from frozen with about 2 extra minutes in the oven.
Do you have to chill the dough?
Yes, chill it for 30 minutes. Cold dough spreads less, so the cookies stay thick and fudgy instead of flat.
Why This Hot Chocolate Cookie Recipe Works
Creaming the butter with brown and white sugar builds a tender base, and the brown sugar adds moisture and a slight chew. Beating the mixture for a full 2 minutes gives the cookies enough structure to hold the marshmallows without turning cakey.
Using both cocoa powder and hot cocoa mix gives the cookies a layered flavor. The cocoa powder supplies deep, rich chocolate, and the mix adds the sweet, milky note that makes the cookies taste like the drink.
Chilling the dough for 30 minutes keeps the butter firm so the cookies bake thick, and adding the marshmallows only for the final 2 minutes keeps them puffy instead of melted away.
A small amount of baking soda also reacts with the acid in natural cocoa to help the cookies rise just enough. Combined with the 1/2 teaspoon of salt, it keeps the chocolate flavor bright and balanced instead of flat.
