Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it’s heating, line two baking sheets with parchment paper to ensure easy removal of the cookies later. This preparation is essential to achieve that perfect cookie texture, giving them a wonderful, slightly chewy edge.
Step 2: Whisk the Dry Ingredients
In a medium mixing bowl, add all-purpose flour, cocoa powder, baking soda, and salt. Whisk these ingredients together thoroughly, ensuring there are no lumps—this step is key for evenly distributed chocolate flavor in your Chocolate Marshmallow Swirl Cookies. Set the bowl aside for now.
Step 3: Cream the Butters and Sugars
In a large mixing bowl, cream together the softened unsalted butter, granulated sugar, and brown sugar. Use a hand mixer or stand mixer on medium speed for about 2-3 minutes until the mixture is light and fluffy, indicating that air has been incorporated for a tender cookie base.
Step 4: Add the Egg and Vanilla
Add the egg and vanilla extract into the creamed butter and sugar mixture, beating until everything is well combined. This will help to create a cohesive dough. The batter should look smooth and glossy, which sets the stage for the rich flavor fusion of your Chocolate Marshmallow Swirl Cookies.
Step 5: Combine Wet and Dry Ingredients
Gradually pour the dry ingredients into the wet mixture, gently stirring with a spatula until just combined. It’s crucial not to overmix at this stage, as it ensures your cookies remain soft and chewy rather than tough. The dough should come together into a rich chocolatey texture.
Step 6: Fold in the Chocolate Chips
Carefully fold in the semi-sweet chocolate chips, which will melt beautifully during baking, enhancing the silky chocolate experience. Be gentle to maintain the Cookie dough’s airy quality, ensuring that every bite of your Chocolate Marshmallow Swirl Cookies is packed with melted goodness.
Step 7: Add the Marshmallows
Now it’s time to add that marshmallow magic! Gently fold in the mini marshmallows and marshmallow fluff until they’re evenly distributed throughout the dough. You want to see visible streaks for that delightful swirl effect, guaranteeing gooiness in every bite of your cookies.
Step 8: Scoop Dough onto Baking Sheets
Using a cookie scoop or tablespoon, spoon out dollops of cookie dough onto the prepared baking sheets, spacing them about 2 inches apart. This spacing allows for spreading during baking, creating those beautiful, chewy Chocolate Marshmallow Swirl Cookies that everyone loves.
Step 9: Bake to Perfection
Place the baking sheets in the preheated oven and bake for 8-10 minutes. The edges should be set while the centers remain slightly soft. Keep an eye on them towards the end to avoid overbaking, ensuring that wonderful chocolate and marshmallow swirls remain gooey and indulgent.
Step 10: Cool Before Enjoying
Once baked, let the cookies cool on the baking sheet for about 5 minutes before transferring them to a wire rack. This cooling time helps them firm up without breaking, letting the delicious gooeyness settle. Now, they’re ready to be savored as your Chocolate Marshmallow Swirl Cookies cool off!

Chocolate Marshmallow Swirl Cookies Recipe FAQs
How do I select the right chocolate for my cookies?
Absolutely! For the best flavor, I recommend using semi-sweet chocolate chips, as they provide a perfect balance of sweetness and richness. If you’re looking for a more intense chocolate experience, dark chocolate chips are a fantastic alternative. Just ensure they are high-quality for the best results!
How can I store my Chocolate Marshmallow Swirl Cookies?
To keep your cookies fresh, store them in an airtight container at room temperature for up to one week. If you want to extend their shelf life, you can also refrigerate them, where they’ll stay good for about 10 days. Just make sure they’re in a sealed container to prevent drying out!
What’s the best way to freeze these cookies?
Freezing your Chocolate Marshmallow Swirl Cookies is simple! First, let them cool completely. Then, place them in a single layer in an airtight container or zip-top bag, ensuring a bit of space between them to prevent sticking. They can be frozen for up to 3 months. When you’re ready to enjoy them, simply thaw at room temperature or warm them for a few seconds in the microwave for that freshly baked taste!
How can I troubleshoot if my cookies are too tough?
If your cookies turn out too tough, it’s likely due to overmixing the dough, which can develop gluten. To avoid this, always mix just until combined, and no longer. Remember, gentle folding is key when adding chocolate chips and marshmallows to maintain a light and chewy texture!
Are there any dietary considerations for these cookies?
Yes, indeed! If you’re accommodating dietary restrictions, you can easily make these cookies dairy-free by substituting unsalted butter with vegan butter or margarine. For a vegan version, replace the egg with a flax egg (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water, allowed to sit until gel-like). This keeps your Chocolate Marshmallow Swirl Cookies delicious, and everyone can enjoy them!
