Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies
Step 1: Prep Work
Begin by preheating your oven to 350°F (175°C) and lining your baking sheets with parchment paper. This creates a non-stick surface for your Chocolate Marshmallow Swirl Cookies, ensuring they come off easily after baking. While you’re preparing the ingredients, enjoy the rich aroma of the warming oven as it sets the stage for these delightful treats.
Step 2: Mixing Dough
In a large mixing bowl, cream together the unsalted butter, granulated sugar, and brown sugar until the mixture appears light and fluffy, about 3-5 minutes. Next, add the room temperature eggs and pure vanilla extract, mixing until they’ve completely blended in, leaving no streaks. Gradually incorporate the all-purpose flour, unsweetened cocoa powder, and kosher salt, stirring just until combined to maintain a tender texture.
Step 3: Incorporate Marshmallows
Fold in the chopped real marshmallows gently into the chocolate dough, taking care to distribute them evenly without overmixing. This step adds those gooey, delightful swirls that make your Chocolate Marshmallow Swirl Cookies absolutely irresistible. You’ll want to see pockets of marshmallow throughout the dough that will create that lovely melted center once baked.
Step 4: Chill Dough
If the dough feels too sticky to manage, cover the mixing bowl with plastic wrap and chill the dough in the refrigerator for about 30 minutes. Chilling helps firm up the consistency, making it easier to handle when you shape the cookies. While the dough chills, you can clean up the workspace, making your cookie baking experience even more enjoyable.
Step 5: Shape Cookies
Once chilled, take tablespoon-sized amounts of dough and drop them onto your prepared baking sheets, ensuring they are spaced about 2 inches apart. This spacing allows the Chocolate Marshmallow Swirl Cookies to spread while baking without merging into one another. You can use a cookie scoop for uniformity if you have one handy!
Step 6: Bake
Place the baking sheets in the preheated oven and bake for 10-12 minutes. For even cooking, rotate the sheets halfway through the baking time. Keep an eye on them; they’re ready when the edges are set and the marshmallows begin to puff slightly, indicating that the gooey centers will be deliciously melted.
Step 7: Cool and Serve
After baking, let the Chocolate Marshmallow Swirl Cookies cool on the baking sheet for about 5 minutes. This allows them to firm up slightly before transferring them to a wire rack to cool completely. Enjoy them warm or at room temperature, appreciating every bite of this delightful treat that perfectly balances chocolatey goodness with marshmallow magic!

Make Ahead Options
These Chocolate Marshmallow Swirl Cookies are fantastic for meal prep! You can prepare the dough up to 24 hours in advance; simply cover it with plastic wrap and refrigerate. If you want to extend that timeframe, shaped cookie balls can be frozen for up to 3 months; just arrange them on a baking sheet to freeze, then transfer to an airtight container. When you’re ready to bake, there’s no need to thaw—the cookies can go straight from the freezer to the preheated oven, adding a few extra minutes to the baking time. This way, you’ll save time on busy weeknights while still enjoying fresh, delicious treats that are just as delightful!
How to Store and Freeze Chocolate Marshmallow Swirl Cookies
Room Temperature: Store baked cookies in an airtight container at room temperature for up to 5 days to keep them fresh and delicious.
Freezer: For longer storage, freeze unbaked cookie dough in shaped balls. They can be kept for up to 3 months—just increase baking time slightly if baking from frozen.
Reheating: To enjoy warm cookies again, microwave for about 10-15 seconds or warm in a preheated oven for a few minutes until heated through.
Thawing: If needed, allow frozen baked cookies to thaw at room temperature for about 30 minutes before enjoying, maintaining their soft and gooey texture.
