Ingredients:
- 1 ¾ cups (220 g) all-purpose flour
- 1/2 cup (40 g) unsweetened cocoa powder
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup (227 g) unsalted butter, softened
- 3/4 cup (150 g) granulated sugar
- 3/4 cup (165 g) packed light brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup (170 g) semi-sweet chocolate chips
- 1 cup (100 g) mini marshmallows
Cookie Dough Preparation
Mixing the Dry Ingredients
To begin crafting these delightful Chocolate Marshmallow Swirl Cookies, let’s get our dry ingredients ready. In a medium-sized bowl, whisk together the 1 ¾ cups (220 g) of all-purpose flour, ½ cup (40 g) of unsweetened cocoa powder, 1 teaspoon of baking soda, and ¼ teaspoon of salt. Whisking these ingredients together thoroughly ensures that the leavening agent (baking soda) and the salt are evenly distributed throughout the flour and cocoa mixture. This is a crucial step for consistent cookie texture and flavor. Set this bowl aside for now.
Creaming the Butter and Sugars
In a large mixing bowl, or the bowl of your stand mixer fitted with the paddle attachment, cream together the 1 cup (227 g) of softened unsalted butter with ¾ cup (150 g) of granulated sugar and ¾ cup (165 g) of packed light brown sugar. You want to beat these together until the mixture is light and fluffy, which usually takes about 2 to 3 minutes on medium speed. This creaming process incorporates air into the dough, which contributes to the cookies’ tender texture and prevents them from being too dense. Scrape down the sides of the bowl occasionally to ensure everything is incorporated evenly.
Adding Eggs and Vanilla
Next, add the 2 large eggs to the creamed butter and sugar mixture, one at a time, beating well after each addition until fully incorporated. Adding the eggs one by one helps them emulsify better with the fat, leading to a smoother, more cohesive dough. Following the eggs, mix in the 1 teaspoon of vanilla extract. Vanilla extract adds a wonderful depth of flavor that complements both the chocolate and marshmallow perfectly.
Combining Wet and Dry Ingredients
Now, it’s time to bring the dry ingredients into the wet mixture. Gradually add the flour mixture to the wet ingredients in three additions, mixing on low speed just until combined. Be careful not to overmix the dough once the flour is added, as this can develop the gluten too much and result in tough cookies. A gentle mix is key here.
Incorporating the Chocolates and Marshmallows
Finally, gently fold in the 1 cup (170 g) of semi-sweet chocolate chips and the 1 cup (100 g) of mini marshmallows. You can do this with a sturdy spatula or by briefly using the mixer on its lowest speed. Ensure the chocolate chips and marshmallows are distributed as evenly as possible throughout the dough. The marshmallows will melt and create lovely swirls as the cookies bake, so don’t worry if they aren’t perfectly spread.
Baking the Cookies
Chilling the Dough (Optional but Recommended)
While not strictly mandatory, chilling the dough for at least 30 minutes in the refrigerator can significantly improve the texture and prevent excessive spreading. This allows the fats to solidify, which in turn slows down their melting during baking. If you have the time, I highly recommend this step for a thicker, chewier cookie.
Preheating the Oven and Preparing Baking Sheets
Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone baking mats. Parchment paper is excellent for preventing sticking and making cleanup a breeze. If you don’t have parchment paper, you can lightly grease your baking sheets, but be sure to do so evenly to avoid oily spots on your cookies.
Scooping and Baking the Cookies
Using a medium-sized cookie scoop (about 1.5 tablespoons), drop rounded balls of dough onto the prepared baking sheets, leaving about 2 inches of space between each cookie to allow for spreading. You want to ensure they have enough room to expand without touching each other and merging into one giant cookie.
Baking Time and Doneness
Bake for 10 to 12 minutes, or until the edges of the cookies are set and slightly firm to the touch, but the centers still look a little soft and gooey. The marshmallows will begin to puff up and may show some golden-brown spots. Keep a close eye on them during the last few minutes of baking, as ovens can vary. Overbaked cookies will lose their delightful chewiness.
Cooling the Cookies
Once baked, let the cookies cool on the baking sheets for 5 minutes before carefully transferring them to a wire rack to cool completely. This initial resting period on the hot baking sheet allows the cookies to firm up further, preventing them from breaking when you move them. As they cool on the wire rack, the internal structure will continue to set, resulting in the perfect chewy texture. Enjoy these irresistible chocolate marshmallow swirls once they’ve reached room temperature!

There you have it! This Chocolate Marshmallow Swirl Cookies Recipe is a guaranteed crowd-pleaser, perfect for cozy nights in, holiday gatherings, or simply satisfying that sweet craving. The delightful combination of rich chocolate and gooey marshmallow creates a truly irresistible treat. The beauty of these cookies lies not just in their deliciousness but also in their adaptability.

Frequently Asked Questions:
Q: How do I store these Chocolate Marshmallow Swirl Cookies?
A: Once completely cooled, store these cookies in an airtight container at room temperature for up to 3-4 days. You can also freeze them, either as baked cookies or as dough balls, for longer storage.
Q: My marshmallows are melting too much. How can I prevent this?
A: Ensure your marshmallows are cut into smaller pieces before swirling. You can also chill the dough briefly before baking, which helps the marshmallows hold their shape a little better. Don’t overbake the cookies; they should be slightly soft in the center.
