Step-by-Step Instructions
Here’s how to make Chocolate Marshmallow Swirl Cookies:
Prepare the Cookie Dough:
- Preheat the Oven: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats for easy cleanup.
- Cream the Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar using an electric mixer until light and fluffy, about 3 minutes.
- Add the Eggs and Vanilla: Beat in the eggs one at a time, followed by the vanilla extract. Continue mixing until smooth.
- Combine the Dry Ingredients: In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until combined. Be careful not to overmix.
- Fold in the Chocolate Chips: Gently fold in the chocolate chips, ensuring an even distribution throughout the dough.
Shape and Bake the Cookies:
- Scoop the Dough: Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.
- Add the Marshmallows: Press a few mini marshmallows (or halves of larger marshmallows) into the top of each cookie dough ball. You can also swirl them slightly into the dough for a marbled effect.
- Bake: Bake in the preheated oven for 10-12 minutes, or until the edges of the cookies are set and slightly golden. The centers may still look soft, but they will firm up as they cool.
- Cool: Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.

Additional Tips for Chocolate Marshmallow Swirl Cookies
Here are some tips to ensure your Chocolate Marshmallow Swirl Cookies turn out perfectly:
- Don’t Overbake: Since the marshmallows can burn if left in the oven too long, keep an eye on the cookies and remove them when the edges are golden but the centers are still soft.
- Use Mini Marshmallows: Mini marshmallows work best because they melt more evenly. If using larger marshmallows, cut them into smaller pieces before adding them to the dough.
- Swirl the Marshmallows Gently: If you’re swirling the marshmallows into the dough, do so gently to avoid over-mixing and making the cookies too sticky.
- Refrigerate the Dough: If the dough is too soft or sticky to handle, chill it in the refrigerator for 15-30 minutes before scooping and baking.
- Customize the Marshmallow-to-Chocolate Ratio: You can increase or decrease the number of marshmallows in each cookie depending on how gooey or chocolatey you want the final result.
- Use a Cookie Scoop: A cookie scoop helps ensure that the cookies are all the same size, leading to even baking.
