Easy Hot Chocolate Cookies Ready in 25 Minutes

These hot chocolate cookies are fudgy, rich with cocoa, and finished with toasted marshmallows on top, just like a mug of hot cocoa. One bite and it’s basically dessert and a warm drink in one.

Why You’ll Love These Hot Chocolate Cookies

They use real cocoa powder and hot chocolate mix, so the flavor is deep and unmistakably cocoa-forward. That double dose of chocolate is what makes these hot chocolate cookies taste like more than a regular chocolate cookie.

The toasted marshmallow topping gives them that campfire, hot-cocoa-by-the-fire feeling in cookie form.

They also come together with basic pantry staples, no chilling required, so a batch is ready in well under 30 minutes.

Ingredients You’ll Need

• 1/2 cup unsalted butter, softened — creaming it with the sugar builds the base structure for a soft, fudgy cookie.
• 3/4 cup granulated sugar — sweetens the dough and helps the edges set as they bake.
• 1 large egg and 1 teaspoon vanilla extract — bind the dough together and round out the flavor.
• 1 1/4 cups all-purpose flour — spoon and level it so the cookies don’t turn out dry or cakey.
• 1/3 cup unsweetened cocoa powder — the main source of chocolate flavor in this dough.
• 2 packets (1 oz each) hot chocolate mix — adds that instant-cocoa sweetness and flavor; mixes with marshmallow bits work especially well here.
• 1/2 teaspoon baking soda and 1/4 teaspoon salt — help the cookies spread evenly and balance the sweetness.
• 1/2 cup mini marshmallows, plus more for topping — folded into the dough and pressed on top for gooey pockets throughout.
• 1/2 cup semisweet chocolate chips — melt into pockets alongside the marshmallows.

How to Make Hot Chocolate Cookies

1. Preheat your oven to 350°F and line two baking sheets with parchment paper.
2. Cream the softened butter and granulated sugar together for about 2 minutes, until light and fluffy.
3. Beat in the egg and vanilla extract until fully combined.
4. Whisk the flour, cocoa powder, hot chocolate mix, baking soda, and salt together in a separate bowl, then add to the wet ingredients and mix just until combined.
5. Fold in the chocolate chips and 1/2 cup mini marshmallows.
6. Scoop 1 1/2-tablespoon balls of dough onto the prepared sheets, spacing them 2 inches apart.
7. Bake at 350°F for 9 to 10 minutes, until the edges are set but the centers still look soft.
8. Press 2 to 3 extra mini marshmallows onto each warm cookie and return to the oven for 1 minute to soften them, or toast lightly with a kitchen torch.
9. Cool the cookies on the pan for 5 minutes before transferring to a wire rack.

Tips for Success

Add the marshmallows in two stages. Marshmallows folded into the raw dough tend to melt away during baking, so pressing extra ones on top afterward is what gives these hot chocolate cookies their gooey, marshmallow-topped look.

Don’t overbake. The most common mistake is leaving these in until they look fully firm — pull them while the centers still look slightly underdone, since they continue to set as they cool.

Use fresh hot chocolate mix. Stale mix can taste flat or overly sweet without much cocoa punch, so a fresh packet keeps the chocolate flavor sharp.

Variations to Try

Add a pinch of cinnamon or cayenne to the dough for a Mexican hot chocolate twist.

Drizzle the cooled cookies with melted white chocolate for extra sweetness and contrast.

What to Serve With It

A mug of actual hot cocoa alongside these hot chocolate cookies leans all the way into the theme.

For a holiday cookie tray, pair them with our Pumpkin Whoopie Pies for a mix of chocolate and spiced flavors.

FAQs

Can I use regular marshmallows instead of mini? Yes — cut large marshmallows in half and press them cut-side down onto the cookies after baking, the same way you would with the minis.

How do I store these? Store in an airtight container at room temperature for up to 4 days; the marshmallow topping is best within the first 2 days before it firms up.

Can I freeze the dough? Yes — scoop the dough into balls, freeze on a tray until solid, then transfer to a freezer bag for up to 2 months. Bake straight from frozen, adding 1 to 2 extra minutes.

Can I skip the marshmallow topping? Yes — the cookies are still fudgy and chocolatey without it, just leave out the final marshmallow-pressing step.

Final Thoughts

These hot chocolate cookies pack all the cozy flavor of a mug of cocoa into a fudgy, marshmallow-topped cookie that’s ready in about 25 minutes.

Bake a batch on a cold afternoon — they’re just as good the next day, though the marshmallows are gooiest fresh from the oven.
