Hot cocoa cookies with marshmallows bring the cozy flavor of a winter mug drink into a soft, fudgy cookie that finishes with a toasted marshmallow on top. This recipe uses real cocoa powder and a short rest time so the dough bakes up thick instead of spreading thin. You get a chewy chocolate cookie with a gooey, lightly browned marshmallow cap in about 30 minutes of active work.
The method is built for reliable results: we cream the butter and sugar just enough, chill the dough briefly, and bake at a moderate oven temperature. That keeps the centers tender while the edges set. If you like the taste of hot chocolate but want it in handheld form, this is the bake to make.

Why You’ll Love These Hot Cocoa Cookies With Marshmallows
- Soft, brownie-like crumb from a high cocoa ratio and one egg yolk for richness.
- Toasted marshmallow tops that stay stretchy instead of hardening.
- One bowl of dough, no mixer required beyond a basic hand beat.
- Freezer-friendly dough you can bake in small batches.
Ingredients You’ll Need
- 115 g unsalted butter, softened – gives structure and a tender bite
- 100 g granulated sugar – balances cocoa bitterness
- 90 g light brown sugar – adds moisture and chew
- 1 large egg, room temperature – binds the dough
- 1 egg yolk – extra richness for fudgy texture
- 1 tsp vanilla extract – rounds the chocolate note
- 150 g all-purpose flour – base structure
- 45 g Dutch-process cocoa powder – deep cocoa flavor
- 1/2 tsp baking soda – lift without cakey spread
- 1/4 tsp salt – sharpens sweetness
- 90 g mini marshmallows – the topping
- 60 g milk chocolate chips – pockets of melt
Ingredient Substitutions
Unsalted butter: Replace with an equal weight of salted butter, then cut the added salt to a pinch. Salted butter browns a little faster at the edges, so check the cookies at 9 minutes. The flavor stays close but the tops may color sooner than with unsalted. The hot cocoa cookies with marshmallows works well for weeknight cooking when time is limited.
Dutch-process cocoa powder: Use natural unsweetened cocoa in the same weight if needed. Natural cocoa is more acidic and lighter in color, so the cookies taste sharper and look less dark. Add 1/4 tsp cream of tartar to keep the crumb tender since the baking soda reaction changes. Storing leftover hot cocoa cookies with marshmallows correctly keeps it tasting good for days.
Mini marshmallows: Swap for 12 large marshmallows cut into quarters. Large pieces hold shape better under heat and brown more slowly, giving a thicker cap. Watch the oven closely because the sugar can scorch if left past 2 minutes of broil. For the best results with this hot cocoa cookies with marshmallows, read through all the steps before starting.
All-purpose flour: Replace with a 1-to-1 gluten-free baking blend for a wheat-free version. Most blends include xanthan gum, so the dough stays cohesive. Expect a slightly more delicate edge that benefits from 5 minutes of pan cooling before moving.
Step-by-Step Instructions
- Heat the oven to 180°C / 350°F and line two trays with parchment. Softened butter beats with both sugars on medium-low heat off the stove for 2 minutes until smooth, not fluffy.
- Add the whole egg, yolk, and vanilla. Beat 1 minute until the mix looks glossy and slightly thickened.
- Stir in flour, cocoa, baking soda, and salt with a spatula until no dry streaks remain. Fold in chocolate chips. Rest dough 10 minutes so cocoa hydrates.
- Scoop 1.5 tbsp portions onto trays, 2 inches apart. Bake 9 minutes until edges look set and centers look soft.
- Press 4–5 mini marshmallows onto each cookie. Return to oven 2 minutes until marshmallows puff and show golden and crispy spots.
- Cool on tray 5 minutes then move to a rack. The tops firm as they cool and stay chewy.
Pro Tips
Chill the scooped dough for 15 minutes if your kitchen is warm; cold dough spreads less and keeps a thicker center. For even baking, rotate the trays once at the halfway point so the back rows don’t overbake. If you want a stronger cocoa taste, sift the cocoa with the flour so it mixes without clumps. A quick broil at the end mimics a toasted mug-topping; keep the door cracked and watch closely. Learn proper cookie baking cues from tested sources when scaling batches. Pair the bake with a lentil soup for a sweet-savory spread.
Common Mistakes to Avoid
Overbeating the butter and sugar turns the crumb cakey instead of fudgy; stop at smooth. Adding marshmallows too early makes them melt into the dough and vanish, so wait until the cookies are baked. Skipping the rest time lets cocoa stay dry and the flavor reads flat. Crowding the tray causes uneven heat and pale centers; leave space. Using cold egg straight from the fridge can seize the butter, so bring it to room temperature first.
Serving Suggestions
Serve the cookies slightly warm so the marshmallow stretches when pulled apart. A small scoop of vanilla ice cream beside each cookie adds a cold contrast to the soft chocolate. For a party board, place them next to avocado smoothie cups for a kid-friendly table. Dust the plate with extra cocoa for a clean look. They also pack well in lunch boxes once fully cooled.
Storage and Reheating
Keep baked cookies in an airtight container at room temperature for up to 3 days; the marshmallow stays soft under lid seal. For longer hold, freeze the plain dough balls and bake from frozen with 1 extra minute. Reheat a cookie in a 160°C / 325°F oven for 4 minutes to re-soften the top. Don’t leave baked goods out more than 2 hours in a warm room. The recipe keys tag helps sort this under make-ahead treats.
Recipe Variations
Peppermint Version
Add 1/2 tsp peppermint extract with the vanilla and use 40 g crushed candy cane on top instead of some chips. The cookies taste like a peppermint patty with a soft center. The candy melts slightly and re-hardens as a thin shell.
Double Chocolate
Replace 30 g flour with 30 g more cocoa and use dark chocolate chips. The result is denser and less sweet, closer to a brownie bite. Bake 1 minute less to keep the middle from drying.
Nutty Crunch
Fold 50 g toasted walnuts into the dough before scooping. The nuts add a firm bite against the soft mashmallow. Watch the bake time since added moisture is low and edges brown faster. A cheese bake on the side balances the sweet plate.
Snow Cap
After cooling, drizzle 40 g white chocolate over the marshmallow top for a contrast look. The extra layer sets in 10 minutes in the fridge. It adds sweetness, so cut granulated sugar by 10 g if you prefer less. See recipe tags for similar dessert labels.

Ingredients
Instructions
-
Heat oven and line trays
Heat the oven to 180°C / 350°F and line two baking trays with parchment paper. This moderate temperature helps the cookies bake thick instead of spreading thin, so prepare both trays before mixing the dough.
-
Cream butter and sugars
Place the softened butter in a bowl and beat with both sugars on medium-low heat off the stove for 2 minutes until smooth, not fluffy. Stop as soon as the mixture looks evenly combined to keep the crumb fudgy rather than cakey.
-
Add egg and vanilla
Add the whole egg, egg yolk, and vanilla extract to the butter mixture. Beat for 1 minute until the mix looks glossy and slightly thickened, which shows the emulsion is ready for dry ingredients.
-
Stir dry ingredients
Stir in the flour, cocoa powder, baking soda, and salt with a spatula until no dry streaks remain. The dough will be dark and thick, so scrape the sides well to avoid clumps of cocoa.
-
Fold in chocolate chips
Fold the milk chocolate chips into the dough until they are evenly distributed. These create pockets of melt when the cookies bake, so make sure none sit on the very bottom of the bowl.
-
Rest the dough
Let the dough rest for 10 minutes so the cocoa hydrates and the flour absorbs moisture. Skipping this step leaves the cocoa dry and the baked flavor flat, so set a timer and wait.
-
Scoop and space dough
Scoop 1.5 tbsp portions of dough onto the lined trays, leaving 2 inches apart for even heat. Crowding the tray causes pale centers, so use both trays and keep the spacing consistent.
-
Bake cookie bases
Bake the cookies for 9 minutes until the edges look set and the centers look soft to the touch. Rotate the trays once at the halfway point so the back rows do not overbake.
-
Add marshmallows and finish
Press 4–5 mini marshmallows onto each hot cookie, then return to the oven for 2 minutes until the marshmallows puff and show golden, crispy spots. Cool on the tray for 5 minutes so the tops firm but stay chewy before moving to a rack.

- Reheating: Reheat a cookie in a 160°C / 325°F oven for 4 minutes to re-soften the top, and do not reheat the same portion more than once.
- Make ahead: Freeze plain dough balls and bake from frozen with 1 extra minute; for a sweet-savory spread try our vegetable stir fry on the side.
- Pro tip: Chill scooped dough 15 minutes in a warm kitchen so it spreads less and keeps a thicker center.
