These Hot Chocolate Cookies deliver all the comfort of a steaming mug of cocoa in cookie form. Crispy edges give way to a gooey marshmallow and soft chocolate middle that feels just right for chilly days or any moment you crave something extra special with your dessert.
The first time I made these I was snowed in at home and the smell alone had everyone lining up at the oven. They have since become a holiday season tradition we never skip.

- Baking soda: helps the cookies rise a fresh box makes all the difference
- Salt: enhances all the flavors in the dough use a fine salt so it blends well
- Freeze dried mini marshmallows or mini marshmallows or white chocolate chips: for texture and extra gooeyness I always go for marshmallows but white chips are great too
- Large marshmallows: for topping go for fresh so they melt nicely on the cookies
- Semi sweet chocolate chips: for the chocolate topping use a good quality chip that melts smoothly
Step-by-Step Instructions
- Cream the Butter and Sugars:
- Whip slightly cold butter with both white and brown sugars in a stand mixer fitted with a paddle for about five minutes the mixture will get light and fluffy and this helps the cookie edges crisp
- Add Wet Ingredients:
- Beat in the egg vanilla and milk until combined the dough will look glossy and smooth and will smell warm from the vanilla
- Combine Dry Ingredients:
- Use a separate bowl for flour cornstarch cocoa powder hot cocoa mix baking soda salt and the marshmallow bits mixing them together so all the chocolate stays evenly distributed
- Mix Wet and Dry Together:
- Add the dry ingredient blend to the wet in the stand mixer use low speed and mix until just combined this keeps the cookies tender
- Chill the Dough:
- Wrap the dough well and refrigerate for at least two hours or up to two days this makes scooping easier and keeps the centers gooey
- Preheat and Prep:
- Line baking sheets with parchment and preheat your oven to three hundred fifty degrees Fahrenheit give yourself thirty minutes after removing the dough from the fridge before you start baking
- Shape and Bake:
- Roll dough into balls about two tablespoons each and space them out well on the baking sheet so they do not run into each other bake for nine minutes just until they start looking set at the edges
- Add Marshmallow and Finish Baking:
- Remove the tray and press half a large marshmallow on top then return to the oven for about two and a half minutes the marshmallow will melt slightly but not brown
- Cool and Set:
- Rest the cookies for about twelve minutes then shift them to a cooling rack so they finish firming up
- Add Chocolate Topping:
- Melt chocolate chips gently until smooth then spoon chocolate over each marshmallow covered cookie let them stand for about ten minutes or until the chocolate firms before serving or storing

My favorite part is the way the marshmallow melts into the chocolate topping creating almost a homemade candy bar experience every bite brings back memories of snowy afternoons making hot chocolate after sledding with family
Storage Tips
After the chocolate topping is set place cookies in a single layer in an airtight tin Putting parchment between layers prevents sticking If you want to save them longer freeze the dough rounds on a baking sheet then store in a zip bag for up to two months and bake straight from the freezer just add a minute or two to the baking time
Ingredient Substitutions
You can swap light brown sugar for dark brown for a deeper flavor Try mini marshmallows if you can not find the freeze dried variety and if you are out of cocoa powder add extra hot cocoa mix in its place but expect a milder flavor Dairy free butter and plant milk also work really well in this dough
Serving Suggestions
Serve these slightly warm for true melted marshmallow goodness I like to offer them on a platter with mugs of real hot chocolate topped with extra marshmallows or let kids help decorate the tops with sprinkles for a festive look These are always a hit at cookie swaps or holiday bake sales
