Chocolate Marshmallow Swirl Cookies capture everything I love in a homemade dessert rich chocolate flavor soft gooey marshmallow centers and a cookie that stays tender and decadent every time. This easy recipe combines pantry staples for a playful treat that looks as fun as it tastes. When I made these for my daughter’s birthday party they disappeared in minutes and became the most requested sweet in our house
My first batch of these cookies made my whole kitchen smell like a chocolate shop and I remember my family hovering by the oven waiting to sneak the first warm one right off the tray
Ingredients
- All purpose flour: creates the structure for tender chewy cookies Choose a fresh bag for best results as old flour can give flat cookies
- Unsweetened cocoa powder: provides intense chocolate flavor Look for Dutch processed for smoother taste
- Baking soda: encourages spread and lift in each cookie Test freshness by dropping a bit into vinegar it should fizz
- Salt: balances sweetness and brings out chocolate flavor Use fine sea salt for even distribution
- Unsalted butter: forms the rich tender base Always start with room temperature butter for proper creaming
- Granulated sugar: gives sweetness and helps cookies brown smoothly Organic cane sugar also works well here
- Large eggs: bind the dough ingredients together for chewy texture Let them warm to room temperature so batter mixes evenly
- Vanilla extract: adds warmth and rounds out chocolate Use real vanilla if possible for the best aroma
- Marshmallow fluff: creates the signature oozy swirl If you want an extra lofty center use melted marshmallows instead
Step-by-Step Instructions
- Mix Dry Ingredients:
- In a medium bowl whisk together the all purpose flour cocoa powder baking soda and salt until well blended This is key for even texture in every bite
- Cream Butter and Sugar:
- In a large bowl use a mixer to beat the room temperature butter with the granulated sugar Continue mixing until the mixture turns pale and fluffy about three to four minutes Scrape the sides of the bowl as you go
- Add Eggs and Vanilla:
- Beat in the eggs one at a time letting each fully blend before adding the next Stir in the vanilla extract for a rich fragrance
- Combine Wet and Dry:
- Add the dry ingredients to the wet mixture gradually and mix on low speed until just combined This prevents a tough dough Avoid overmixing as that can make cookies dry
- Chill the Dough:
- Cover the bowl and chill in the fridge for at least an hour This step makes the dough easier to handle and helps cookies bake up thick and soft
- Preheat Oven:
- Set your oven to three hundred fifty degrees Fahrenheit Line two baking sheets with parchment or silicone mats To save dishes you can reuse the parchment in batches
- Form Cookies:
- Scoop the chilled dough into balls The size of a tablespoon works great Place them spaced apart on your sheets Make a small indent in each ball and spoon in a teaspoon of marshmallow fluff Swirl with a toothpick for the signature look
- Bake:
- Place the sheets in your hot oven Bake for ten to twelve minutes until the edges look set but the center stays soft You can dollop more fluff halfway through if you want extra marshmallow magic
- Cool on Pan:
- Let the cookies rest on the sheet for five minutes The marshmallow needs to set before you move them to a wire rack to cool completely

When I swirl the marshmallow into the dough I always let my kids take over They love watching the swirls form and each cookie comes out totally unique Last winter we shared these with neighbors after sledding and the marshmallow goo made everyone grin
Storage Tips
Once baked these cookies can be stored in an airtight container at room temperature for up to five days If you want to keep them fresh even longer you can freeze either the raw dough balls or the baked cookies For the dough freeze on a tray first then transfer to a freezer bag For baked cookies just layer in a box with parchment so they do not stick together Thaw at room temperature or give a quick warm up in the oven for that justbaked taste
Ingredient Substitutions
You can swap out marshmallow fluff for actual mini or large marshmallows if you want a slightly different texture or look For a gluten free version use your favorite cup for cup flour blend Unsalted butter can be swapped with coconut oil for a subtle flavor twist and dairy free option Just be sure to chill the dough well as coconut oil doughs get soft quickly
Serving Suggestions
Serve these cookies with a glass of cold milk or alongside a scoop of ice cream for a deluxe dessert Sometimes I even sandwich a layer of extra fluff or chocolate spread between two cookies for a wow worthy treat They also look beautiful stacked on a holiday cookie platter or wrapped as edible gifts

Cultural and Historical Context
Chocolate and marshmallow make a classic pairing that goes way back to American campfire traditions Think s’mores and chilly nights by the fire turning into ooey gooey desserts These cookies capture that nostalgia in a simple easy treat you can bake year round no campfire required
