- 3/4 cup (150 g) granulated sugar: Sweetens the dough with a pleasant crunch.
- 1/2 cup (100 g) packed light brown sugar: Infuses a subtle molasses hint and chewier texture.
- 1 large egg: Acts as the binding agent to hold everything together beautifully.
- 1 teaspoon vanilla extract: Enhances the warm, comforting aroma and taste.
- 1/2 cup (90 g) semi-sweet chocolate chips: Melted bursts of chocolate that punctuate every bite.

How to Make Chocolate Marshmallow Swirl Cookies Recipe
Step 1: Prep the Oven and Ingredients
Start by preheating your oven to 350°F (175°C) and preparing two baking sheets with parchment paper or silicone mats. This prevents sticking and helps your cookies bake evenly. Measuring all ingredients beforehand makes the process smooth and stress-free.
Step 2: Mix the Dry Ingredients
Whisk together the flour, cocoa powder, baking soda, and salt in a medium bowl. This ensures your cookies have an even chocolate color and no lumps, setting the stage for a flawless dough.
Step 3: Cream the Butter and Sugars
Using a mixer, cream the softened butter with granulated and brown sugars until the mixture becomes light and fluffy. This aeration is the secret to cookies with tender crumbs and a melt-in-your-mouth texture.
Step 4: Add the Wet Ingredients
Beat in the egg and vanilla extract until everything is well combined, ensuring a smooth batter that will bind your cookies perfectly.
Step 5: Combine Wet and Dry
Gradually add the dry ingredients to your wet mix. Mix on low speed just until combined—overmixing can make cookies tough, so gentle is better here.
Step 6: Fold in the Chocolate Chips
Gently fold in the chocolate chips to sprinkle melty, decadent chocolate chunks throughout your dough.
Step 7: Add the Marshmallow Swirl
This is where the magic truly happens. Incorporate the mini marshmallows and optional marshmallow fluff with care, folding just enough to create pretty swirls without losing their shape. This gives your cookies that irresistible gooey texture that sets this Chocolate Marshmallow Swirl Cookies Recipe apart.
Step 8: Scoop and Bake
Drop rounded spoonfuls of dough onto your baking sheets, spacing them about 2 inches apart to allow for spreading. Bake for 8-10 minutes until the edges are firm but centers remain soft. Watch as marshmallows melt and caramelize slightly, adding a toasty note to your treats.
Step 9: Cool and Enjoy
Allow the cookies to rest on the baking sheet for at least 5 minutes before transferring to a cooling rack. This step ensures they set just right, remaining soft yet sturdy enough to handle.
How to Serve Chocolate Marshmallow Swirl Cookies Recipe

Garnishes
Sprinkle a little extra mini marshmallows or dust with powdered sugar just before serving for a festive touch that catches the eye and adds a hint of extra sweetness. A few chocolate shavings on top can also make them look and taste extra special.
Side Dishes
These cookies pair wonderfully with a cold glass of milk or a warm cup of coffee or hot cocoa. The drinks provide a smooth contrast that enhances the richness and gooey marshmallow texture, creating a perfect indulgence for snack time or dessert.
Creative Ways to Present
Try stacking a few cookies with a dollop of marshmallow fluff between them to make mini cookie sandwiches. Or serve them warm with a scoop of vanilla ice cream and a drizzle of chocolate sauce for a quick and decadent dessert that wows everyone.
Make Ahead and Storage
Storing Leftovers
Keep any leftover cookies in an airtight container at room temperature for up to 3 days. This helps maintain their chewy softness and keeps the marshmallow swirls fresh and gooey.
Freezing
For longer storage, freeze baked cookies in a sealed container or freezer bag for up to 2 months. You can also freeze unbaked dough balls individually on a tray before transferring to bags, making quick, fresh cookies whenever the craving hits.
Reheating
Warm frozen or leftover cookies in the microwave for 10-15 seconds to revive that fresh-baked softness and activate those marshmallow swirls. Alternatively, a few minutes in a preheated 300°F oven works beautifully to restore their just-out-of-the-oven warmth.
FAQs
Can I use regular-sized marshmallows instead of mini marshmallows?
Yes, but cut the regular marshmallows into smaller pieces so they distribute evenly and blend well into the dough, ensuring the perfect swirl without overwhelming the cookies.
What is the purpose of marshmallow fluff in this recipe?
Marshmallow fluff adds an extra dimension of gooey swirls inside the cookies, enhancing the texture and visual appeal. It is optional but highly recommended for that signature melt-in-your-mouth, marshmallow effect.
How do I make sure my cookies stay soft and chewy?
Be careful not to overbake. Remove the cookies from the oven when the edges are set but the centers look slightly underdone. Also, creaming the butter and sugars well ensures a tender, chewy texture.
Can I make this recipe gluten-free?
Absolutely! Substitute the all-purpose flour with a gluten-free flour blend of your choice, ideally one that includes xanthan gum to help with binding and texture. The cookies will still be deliciously chewy and chocolaty.
What is the best way to scoop dough for even-sized cookies?
Using a cookie scoop guarantees uniform cookie sizes and even baking. If you don’t have one, a tablespoon works fine, but try to keep the scoops consistent for best results.

Ingredients
Dry 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
Wet Ingredients:
- 1/2 cup (115 g) unsalted butter, softened
- 3/4 cup (150 g) granulated sugar
- 1/2 cup (100 g) packed light brown sugar
- 1 large egg

Mix-Ins:
- 1/2 cup (90 g) semi-sweet chocolate chips
- 1 cup (50 g) mini marshmallows
- 1/3 cup (60 g) marshmallow fluff (optional)
Instructions
- Prep the Oven and Ingredients: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats to prevent sticking. Measure out all your ingredients to streamline the process.
- Mix the Dry Ingredients: In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. This ensures the cocoa is evenly distributed, and there are no lumps.
- Cream the Butter and Sugars: In a large mixing bowl, use a hand or stand mixer to cream the softened butter, granulated sugar, and brown sugar together until light and fluffy, about 2-3 minutes. The mixture should turn pale and airy—this step is essential for a tender cookie.
- Add the Wet Ingredients: Beat in the egg and vanilla extract, mixing until fully incorporated. Scrape down the sides of the bowl to ensure everything is well combined.
- Combine Wet and Dry: Gradually add the dry ingredients to the wet ingredients in 2-3 additions. Mix on low speed until just combined. Avoid overmixing, as this can lead to tough cookies.
- Fold in the Chocolate Chips: Gently fold in the semi-sweet chocolate chips for bursts of melty goodness in every bite.
- Add the Marshmallow Swirl: Add the mini marshmallows and dollops of marshmallow fluff (if using) into the dough. Use a spatula to fold them in gently, being careful not to overmix. You want visible streaks of marshmallow throughout the dough for a delightful swirl effect.
- Scoop and Bake: Using a cookie scoop or tablespoon, scoop dough onto prepared baking sheets, spacing about 2 inches apart. Bake for 8-10 minutes, or until edges are set but centers remain slightly soft. Watch the marshmallows as they caramelize slightly, adding a toasty flavor.
- Cool and Enjoy: Let the cookies cool on the baking sheet for 5 minutes to firm up before transferring to a wire rack to cool completely. This prevents breakage and ensures perfect texture.
Notes
- For a stronger marshmallow swirl, use the marshmallow fluff; otherwise, mini marshmallows alone will provide gooey texture.
- Do not overmix the dough after adding dry ingredients to keep cookies tender.
- Use parchment or silicone mats on baking sheets to prevent sticking and ensure even baking.
- Store cookies in an airtight container at room temperature for up to 4 days.
- Optional: Add 1/4 teaspoon espresso powder to enhance the chocolate flavor.
