For the Cookie Base
- All-Purpose Flour – This is the backbone of the cookies, providing essential structure; for a gluten-free twist, try a gluten-free flour blend.
- Cocoa Powder – For that rich chocolate flavor; unsweetened cocoa is best for a deep taste.
- Baking Soda – This will give your cookies a lovely rise; always check it’s fresh for the best results.
- Salt – Enhances all the flavors; skip it if you’re on a low-sodium diet.
- Unsalted Butter – Essential for a wonderful texture and flavor; feel free to substitute with vegan butter for a dairy-free option.
- Granulated Sugar – Sweetens your cookies and adds to their delightful texture; coconut sugar is a great less-processed alternative.
- Brown Sugar – Adds chewy moisture and a hint of caramel; you can use either light or dark brown sugar interchangeably.
- Egg – Binds everything together and enriches the flavor; for a vegan choice, swap it out for a flax egg.
- Vanilla Extract – A splash enhances the depth of flavor; opt for pure vanilla for the best outcome.
For the Sweet Additions
- Semi-Sweet Chocolate Chips – Bursting with chocolatey goodness; feel free to use dark chocolate or vegan chocolate for an alternative.

Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C) to ensure a perfect baking environment. While the oven heats up, line your baking sheets with parchment paper, creating a non-stick surface for your Chocolate Marshmallow Swirl Cookies. This simple preparation step is essential for uniform baking and easy cleanup.
Step 2: Combine Dry Ingredients
In a medium-sized bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt. Mix them well until they are fully combined; this should take about 30 seconds. The dry ingredients form the base of your cookie dough and should be thoroughly mixed to avoid clumps, ensuring a rich chocolate flavor throughout.
Step 3: Cream the Butter and Sugars
In a large mixing bowl, cream together the softened unsalted butter, granulated sugar, and brown sugar using an electric mixer. Beat on medium speed for about 2-3 minutes until the mixture is light and fluffy. This process incorporates air into the dough, which is essential for the perfect texture in your Chocolate Marshmallow Swirl Cookies.
Step 4: Add Egg and Vanilla
Next, add in the egg and vanilla extract, mixing thoroughly until well combined. Scrape down the sides of the bowl to make sure everything is evenly incorporated. The egg helps bind the ingredients and enhances the flavor, contributing to the rich indulgence that makes these cookies so delightful.
Step 5: Mix in Dry Ingredients
Gradually add the dry ingredient mixture to the wet ingredients, mixing at low speed until just combined. Take care not to overmix, as this can lead to tougher cookies. The dough should come together nicely, showing a few streaks of flour—this is the perfect stage before folding in your sweet add-ins.
Step 6: Fold in Additions
Gently fold in the semi-sweet chocolate chips, mini marshmallows, and optional marshmallow fluff with a spatula until evenly distributed, but be careful not to overwork the dough. You should see visible streaks of marshmallow fluff and chocolate chips throughout. This step ensures each bite of your cookies will be a delicious mix of flavors and textures.
Step 7: Scoop the Dough
Using a tablespoon or cookie scoop, scoop portions of the dough onto the prepared baking sheets, spacing them about 2 inches apart. This spacing allows the cookies to spread without sticking together while baking. You should have a lovely tray filled with cookie dough ready to become delightful Chocolate Marshmallow Swirl Cookies.
Step 8: Bake the Cookies
Place the baking sheets in the preheated oven and bake for 8-10 minutes. Keep an eye on them as they bake; look for edges that are set and centers that are slightly soft, with gooey marshmallows starting to ooze. This visual cue indicates that your cookies are perfectly baked and ready for cooling.
Step 9: Cooling Time
Once baked, remove the sheets from the oven and let the cookies cool on the baking sheets for about 5 minutes. This allows them to firm up just enough to transfer without breaking. After cooling slightly, carefully transfer the cookies to a wire rack to cool completely. Your Chocolate Marshmallow Swirl Cookies are now ready to be devoured!

Expert Tips for Chocolate Marshmallow Swirl Cookies

Chocolate Marshmallow Swirl Cookies Recipe FAQs
How do I choose ripe ingredients, especially marshmallows?
Absolutely! When selecting marshmallows, look for ones that are plump and fresh. Avoid any that appear dry or have dark spots, as this indicates they may have started to age. Fresh marshmallows will give your cookies that delightful gooeyness we all love!
What is the best way to store leftover cookies?
You can store your Chocolate Marshmallow Swirl Cookies in an airtight container at room temperature for up to a week. This way, they maintain their soft and chewy texture. If you want to keep them fresh longer, consider refrigerating them for up to 2 weeks. Just be sure they are in an airtight container to prevent them from drying out!
Can I freeze these cookies? How do I do it?
Absolutely! To freeze your Chocolate Marshmallow Swirl Cookies, place them in a single layer on a baking sheet and freeze for about 1-2 hours until solid. Once frozen, transfer them to a freezer-safe container or a zip-top bag. They can last for up to three months! When you’re ready to enjoy them, simply reheat from frozen in the oven at 350°F (175°C) for 5-7 minutes for that fresh-baked taste.
What should I do if my cookies spread too much while baking?
If your cookies spread excessively, it could be due to melted butter or overmixing the dough. Always ensure your butter is softened but not melted, and mix until just combined to keep those cookies from turning flat. If you find that they still spread a lot, you can chill the dough for about 30 minutes before baking to help maintain their shape.
Can these cookies be made gluten-free?
Very! You can easily substitute all-purpose flour with a gluten-free flour blend. Just ensure it’s one that contains xanthan gum, as this helps maintain the structure of the cookies. The taste will still be delightful and sweet, just like the original recipe!
Are there any dietary considerations for pets or allergies?
Excellent question! Chocolate is toxic to dogs and other pets, so make sure to keep these cookies out of their reach. Additionally, if you’re baking for someone with allergies, consider using vegan butter, coconut sugar, or a flax egg to accommodate dietary restrictions. Always check the labels of your ingredients to ensure they’re free from allergens like nuts or dairy if needed.
