How to Make Chocolate Marshmallow Swirl Cookies
-
Preheat oven: Start by preheating your oven to 350°F (175°C) and then line your baking sheets with parchment paper for easy cleanup and to prevent sticking.
-
Whisk dry ingredients: In a medium bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt until well combined—this ensures even distribution of flavors.
-
Cream butter and sugars: In a large mixing bowl, cream softened butter with granulated and brown sugars for about 2-3 minutes until the mixture is light and fluffy, creating a creamy base for your cookies.
-
Incorporate egg and vanilla: Add in your large egg and vanilla extract, mixing until everything is fully combined, creating a smooth, decadent batter.
-
Blend in dry ingredients: Gradually add the dry ingredients in 2-3 parts, mixing on low speed just until combined. Don’t overmix—this will help keep the cookies tender.
-
Fold in chocolate and marshmallows: Gently fold in the semi-sweet chocolate chips, followed by the mini marshmallows and optional marshmallow fluff until everything is evenly coated in the dough.
-
Scoop the dough: Using a cookie scoop or tablespoon, drop dough onto the prepared baking sheets, spacing them about 2 inches apart so they have room to spread.
-
Bake the cookies: Place in the oven and bake for 8-10 minutes. They’re ready when the edges are just set, but the centers remain soft and slightly underbaked for that gooey texture.
-
Cool on rack: Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. This helps them firm up slightly while remaining soft inside.
Optional: Drizzle with melted chocolate for an extra touch of indulgence!

Chocolate Marshmallow Swirl Cookies Recipe FAQs
What is the best way to select ripe ingredients for this recipe?
Absolutely! Choose fresh ingredients for the best results. For butter, make sure it’s softened and at room temperature—this matters for a light texture. When selecting eggs, opt for large, fresh eggs. Your mini marshmallows should be soft and free of any dark spots, ensuring they melt beautifully while baking.
How should I store my Chocolate Marshmallow Swirl Cookies?
To keep your cookies soft and chewy, store them in an airtight container at room temperature for up to 1 week. If you’d like to store them for longer, freeze them! Place the cookies in a single layer on a baking sheet until frozen, then transfer to a zip-top bag. They’ll stay fresh for up to 3 months!
Can I freeze the cookie dough for later use?
Yes, you absolutely can! To freeze the dough, scoop it into balls and place them on a baking sheet lined with parchment paper. Freeze until solid, then transfer them to a zip-top bag. You can freeze the dough for up to 3 months. When you’re ready to bake, you can bake them straight from the freezer—just add an extra minute or two to the baking time!
What should I do if my cookies turn out tough?
If your cookies are tough, it’s likely that the dough was overmixed. Make sure to mix just until the ingredients are combined and no more! Also, ensure that you measure your flour correctly. Too much flour can lead to dense cookies. Measuring with a spoon and leveling it off with a knife helps in getting it right!
Are there any dietary considerations for pets or allergies?
Yes! Be cautious of any allergies since this recipe contains common allergens such as wheat (in the flour) and dairy (in the butter). If you’re sharing these cookies with friends or family, it might be a good idea to inform them about these ingredients. Also, remember dogs should not eat chocolate or sugar, so keep these cookies away from your furry friends!
How can I make these cookies even more indulgent?
If you want to enhance the flavor even further, consider adding a sprinkle of sea salt on top just before baking, or drizzle some melted chocolate over the cooled cookies. Additionally, you can experiment with using flavored extracts, like almond or hazelnut, to give them a unique twist!
