Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies
Step 1: Prepare Dough
In a large mixing bowl, whisk together 2 cups of all-purpose flour, ⅔ cup cocoa powder, 1 teaspoon baking soda, and ½ teaspoon salt until well combined. In another bowl, cream together ¾ cup unsalted butter and 1 cup granulated sugar until light and fluffy, about 3-4 minutes using an electric mixer. Add in 1 large egg and mix until fully incorporated. Gradually blend the dry ingredients into the wet mixture until just combined.
Step 2: Incorporate Marshmallows
Gently fold in 1 cup of chocolate chips and 1 cup of mini marshmallows into the cookie dough, ensuring an even distribution. The Chocolate Marshmallow Swirl will come to life as you mix, creating delightful pockets of gooey marshmallow. Be careful not to overmix, as you want to keep the tender texture.
Step 3: Chill Dough
If your dough feels sticky, cover the bowl with plastic wrap and refrigerate it for about 30 minutes. This step helps firm up the dough, making it easier to handle. When properly chilled, the dough should be slightly firmer and easier to scoop, allowing for perfectly shaped cookies.
Step 4: Portion Dough
Preheat your oven to 350°F (175°C) while the dough chills. Line two baking sheets with parchment paper. Use a cookie scoop or your hands to portion the dough into 1.5-inch balls and place them on the baking sheets, leaving about 2 inches between each ball to allow them to spread while baking.
Step 5: Bake
Bake the cookies in the preheated oven for 10-12 minutes, rotating the baking sheets halfway through for even baking. The cookies should puff up and the edges should be set, with the centers appearing soft. Remove them from the oven when they look slightly underbaked, as they will continue to firm up while cooling.
Step 6: Cool
Allow the Chocolate Marshmallow Swirl Cookies to cool on the baking sheets for about 5 minutes before carefully transferring them to wire racks. This resting time helps the cookies maintain their soft, gooey centers. Let them cool completely on the racks, enhancing their texture before serving.

Chocolate Marshmallow Swirl Cookies Recipe FAQs
How do I choose the best marshmallows for this recipe?
Absolutely! For the best marshmallow swirls in your Chocolate Marshmallow Swirl Cookies, opt for quality real marshmallows instead of marshmallow fluff. Real marshmallows melt beautifully and create that signature gooey texture that’s essential for these cookies. Look for marshmallows that are fresh and plump, as they will integrate better into the dough!
How should I store my cookies after baking?
Very simple! Store your Chocolate Marshmallow Swirl Cookies in an airtight container at room temperature for up to 1 week. This method keeps them fresh and chewy! If you happen to have leftovers (which is rare!), place them in the fridge for up to 2 weeks. Just remember to allow them to come to room temperature before enjoying for the best texture.
Can I freeze the dough for later use?
Absolutely! To freeze the unbaked dough balls, shape them first, then lay them out on a baking sheet. Freeze them individually until solid, about 1-2 hours. Once firm, transfer the dough balls to a freezer bag, making sure to remove as much air as possible. They can be kept frozen for up to 3 months.

What should I do if my cookies are spreading too much during baking?
If your Chocolate Marshmallow Swirl Cookies spread excessively, it may be due to warm dough. To fix this, pop the cookie dough back in the fridge for about 30 minutes before baking. Additionally, ensure you’re using a proper amount of flour, and check that your baking soda is fresh. Chill the dough if needed, and your cookies will maintain their lovely shape!
Can I make these cookies gluten-free?
Absolutely! To make your Chocolate Marshmallow Swirl Cookies gluten-free, substitute the all-purpose flour with a gluten-free flour blend.

Are these cookies safe for my pets?
It’s best to keep these cookies away from your pets. While the main ingredients like sugar and flour aren’t toxic to dogs, chocolate is, and it can be harmful or even fatal to pets, depending on the amount ingested.
