Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies
Step 1: Prepare the dough
In a large mixing bowl, combine the unsalted butter, brown sugar, and granulated sugar. Cream them together using an electric mixer until the mixture is light and fluffy, which usually takes about 3 to 5 minutes. Next, add in the eggs one at a time, mixing well after each addition until fully incorporated.
Step 2: Mix dry ingredients
In a separate bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, mixing on low speed until just combined. You’ll notice a beautifully rich chocolate dough beginning to form in your bowl—resist overmixing to ensure a chewy texture in your Chocolate Marshmallow Swirl Cookies.
Step 3: Add marshmallows
Gently fold in the mini marshmallows with a spatula, ensuring they are evenly distributed throughout the dough. If the dough feels too sticky to handle, cover the bowl with plastic wrap and chill in the refrigerator for about 30 minutes. This step not only helps the dough firm up but also makes it easier to scoop and shape into cookies.
Step 4: Shape and bake
Preheat your oven to 350°F (175°C). Line your baking sheets with parchment paper. Using a cookie scoop or tablespoon, drop spoonfuls of dough onto the prepared baking sheets, leaving about 2 inches of space between each one. Bake for 10-12 minutes, or until the edges are set but the centers are still soft and slightly underbaked, allowing them to finish cooking while cooling.
Step 5: Cool and serve
Once baked, remove the chocolate marshmallow swirl cookies from the oven and let them cool on the baking sheet for about 5 minutes. Then, transfer them to a wire rack to cool completely. The cookies will firm up as they cool, revealing that melty marshmallow swirl inside, perfect for enjoying with a glass of milk or a cup of coffee!

Make Ahead Options
These Chocolate Marshmallow Swirl Cookies are perfect for meal prep enthusiasts! You can prepare the cookie dough up to 24 hours in advance by following the initial steps through mixing, then wrap the bowl tightly in plastic wrap and refrigerate. This not only allows the flavors to meld but also makes it easier to scoop later. Additionally, you can shape the dough into individual cookie balls and freeze them for up to 3 months; when ready to bake, simply add a couple of extra minutes to your baking time. To maintain their chewy quality, store baked cookies in an airtight container at room temperature. With these make-ahead tips, you’ll enjoy fresh cookies with minimal fuss on busy weeknights!

Chocolate Marshmallow Swirl Cookies Recipe FAQs
How do I select the perfect marshmallows for my cookies?
Absolutely! Look for marshmallows that are fresh and soft, avoiding any that have dark spots or feel hard. Mini marshmallows are great for a swirl effect, and using real marshmallows rather than fluff will create a better texture. If you want a fun twist, consider flavored marshmallows like strawberry or vanilla, which can add a delightful surprise to your cookie experience.
What’s the best way to store Chocolate Marshmallow Swirl Cookies?
Very! To keep your cookies fresh, store them in an airtight container at room temperature for up to 1 week. If you live in a warm climate, the fridge works too, extending their freshness to 2 weeks. Just remember to let them come back to room temperature before serving to restore that gooey texture!
Can I freeze Chocolate Marshmallow Swirl Cookies?
Absolutely! To freeze, wrap each cookie individually in plastic wrap and place them in an airtight container. They can be frozen for up to 3 months. When you’re ready to enjoy one, simply take it out and let it thaw at room temperature or reheat it in the microwave for about 10-15 seconds for that fresh-baked taste.
What should I do if the cookie dough is too sticky?
No worries! If you find your dough is overly sticky, I recommend chilling it in the refrigerator for about 30 minutes. This helps the butter firm up, making it easier to scoop and shape. If you find that chilling doesn’t help enough, a light dusting of flour on your hands can also aid in handling the dough without drastically changing its texture.
Are Chocolate Marshmallow Swirl Cookies suitable for people with allergies?
It depends on the substitutions used. These cookies contain common allergens such as eggs and gluten. However, you can make them allergy-friendly by using flax eggs as a binder and gluten-free flour as a substitute. Always check the labels on store-bought ingredients, especially for nuts and dairy, to ensure they meet dietary needs.
