Chocolate Hot Cocoa Cookies with Melted Marshmallow
Dense, fudgy chocolate cookies studded with espresso undertones and topped with softened marshmallows and grated chocolate. These capture the cozy warmth of hot cocoa in cookie form, with a crackly top and gooey center. Perfect for winter gatherings, holiday platters, or afternoon indulgence with coffee or cold milk. The two-stage baking technique ensures marshmallows stay pillowy without burning while the cookie base sets.

- 2
Whisk together flour, cocoa powder, espresso powder, baking powder and salt in a medium bowl.
- 3
Beat sugar, eggs and vanilla at low speed until smooth, about 2 minutes. Mix in cooled chocolate until just blended. Add flour mixture in 2 batches on low speed until combined. Refrigerate dough at least 1 hour.

Remove sheets from oven. Gently press a marshmallow half, chocolate side down, into each cookie.

Transfer cookies to racks with a spatula. Cool 5 minutes. Repeat with remaining dough, marshmallows and chocolate using clean parchment. Serve warm.
Tips
Chill dough at least 1 hour before scooping to prevent spreading and ensure fudgy texture and crackly tops.
Use room temperature eggs to emulsify smoothly with the chocolate mixture, improving texture and rise.
Grate chocolate over warm cookies so it melts slightly and adheres; adds visual appeal and extra cocoa flavor.
Good to Know
Store cooled cookies in an airtight container at room temperature up to 3 days. Marshmallow topping softens over time. Freeze undecorated baked cookies up to 1 month; thaw and add marshmallows before serving.
Prepare and chill dough up to 24 hours. Bake cookies without marshmallow topping up to 2 days ahead; add marshmallows and chocolate garnish within 1 hour of serving for best texture.
Serve warm or at room temperature with hot coffee, hot cocoa, or cold milk. Arrange on a platter for holiday gatherings or winter dessert boards.
Common Mistakes
Overmix flour mixture to avoid tough, dense cookies.
Skip dough chill to avoid flat, greasy cookies.
Overbake marshmallows to avoid charring; pull from oven when softened.
Use cold eggs to avoid broken emulsion and separated batter.

FAQ
Can I make these ahead and freeze them?
Yes. Freeze unbaked dough balls up to 2 months or baked undecorated cookies up to 1 month. Thaw dough at room temperature before baking, or bake from frozen adding 2-3 minutes. Top with marshmallows fresh for best texture and appearance.
What if the marshmallows burn before the cookies bake through?
Lower oven temperature by 25 degrees F or check cookies at 10 minutes instead of 12 for the first bake. Alternatively, add marshmallows in the final 3 minutes only, or use mini marshmallows that soften faster.
How long do these keep and how do I prevent them from drying out?
Cookies stay fresh 3 days in an airtight container at room temperature. After 1 day, marshmallows will soften and compress. Store with parchment between layers to prevent sticking. Place a slice of bread in the container to maintain moisture.
