Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies Recipe
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take two baking sheets and line them with parchment paper to prevent the cookies from sticking. This preparation step is crucial for ensuring that your Chocolate Marshmallow Swirl Cookies bake evenly and come out beautifully without any hassle.
Step 2: Mix Dry Ingredients
In a medium mixing bowl, whisk together 2 cups of all-purpose flour, ½ cup of unsweetened cocoa powder, 1 teaspoon of baking soda, and ½ teaspoon of salt. This blend will provide the structure and required chocolate flavor for your cookies. Ensure there are no lumps, as this will help your final cookie dough to be smooth and bubbly when baked.
Step 3: Cream Butter and Sugars
In a larger mixing bowl, add ½ cup of softened unsalted butter, along with ½ cup of granulated sugar and ½ cup of brown sugar. Beat the mixture for about 2-3 minutes until it’s light and fluffy. Remember to scrape down the sides of the bowl halfway through so all your ingredients mix harmoniously. This step ensures a rich base for your Chocolate Marshmallow Swirl Cookies.
Step 4: Incorporate Egg and Vanilla
Add 1 large egg and 1 teaspoon of vanilla extract to your creamed mixture, beating until everything is well combined. You’ll know it’s ready when the mixture is smooth and creamy. Make sure to scrape down the sides again to incorporate any unmixed ingredients. This addition will lend a delightful flavor to your chocolate cookies.
Step 5: Combine Dry Ingredients
Gradually add your dry mixture to the wet ingredients, mixing on low speed to combine without overmixing. Do this in about 2-3 additions, ensuring everything just comes together. The dough should be slightly thick and cohesive but not overly tough, which is key for soft Chocolate Marshmallow Swirl Cookies.
Step 6: Fold in Chocolate Chips
Gently fold in 1 cup of semi-sweet chocolate chips using a spatula or wooden spoon. This step adds delightful pockets of chocolate to your cookies. Try to evenly distribute the chocolate chips without overworking the dough, maintaining its tender texture which is essential for the perfect bite of your cookies.
Step 7: Add Marshmallows
Next, add 1 cup of mini marshmallows, plus marshmallow fluff if desired. Carefully fold these into the dough until you see streaks of marshmallows remain. This step is what makes your Chocolate Marshmallow Swirl Cookies irresistibly gooey and sweet, creating that wonderful contrast in texture everyone loves.
Step 8: Scoop the Dough
Using a cookie scoop or two spoons, drop dollops of cookie dough onto the prepared baking sheets, spacing them about 2 inches apart. This spacing is crucial as they will spread during baking. Keep the shapes somewhat round, as they will hold their form beautifully, showcasing those delightful chocolate and marshmallow swirls.
Step 9: Bake the Cookies
Place your baking sheets in the preheated oven and bake for 8-10 minutes. The edges should be firm and the centers slightly soft when done. Keep a close eye on your marshmallows; they may begin to caramelize, creating a deliciously sweet crust that enhances the flavors of your Chocolate Marshmallow Swirl Cookies.
Step 10: Cooling Time
Once baked, remove the sheets from the oven and let the cookies cool on the baking sheets for about 5 minutes. This resting time allows them to set properly before transferring to a wire rack. The marshmallows will look gooey and inviting, a sure sign that your delicious cookies are ready to enjoy!

How to Store and Freeze Chocolate Marshmallow Swirl Cookies
Room Temperature: Store cookies in an airtight container at room temperature for up to 1 week. This keeps them soft and chewy, ready to satisfy your sweet cravings!
Fridge: If you prefer, you can refrigerate the cookies in a sealed container for up to 2 weeks. Just remember they’ll be a bit firmer when chilled; allow them to come to room temperature before indulging.
Freezer: Freeze cookies by placing them in a single layer on a baking sheet until firm, then transfer to an airtight container or freezer bag. They can be frozen for up to 3 months; thaw at room temperature before enjoying.
Reheating: Warm up cookies in the microwave for about 10-15 seconds for that fresh-baked taste, bringing back the gooey marshmallow goodness in each bite of your Chocolate Marshmallow Swirl Cookies.
Make Ahead Options
These Chocolate Marshmallow Swirl Cookies are perfect for meal prep enthusiasts! You can prepare the cookie dough up to 24 hours in advance by mixing it completely and storing it in an airtight container in the refrigerator. This not only saves time but helps the flavors meld beautifully. If you plan to bake them later, simply scoop the dough onto baking sheets and let it sit at room temperature for about 15 minutes before baking. Additionally, you can freeze the formed cookie dough balls for up to 3 months. Just thaw them overnight in the fridge before baking—ensuring that your cookies are just as delicious as when made fresh!

Tips for the Best Chocolate Marshmallow Swirl Cookies
-
Butter Temperature: Ensure your unsalted butter is at room temperature. This enhances creaming with sugars for a fluffy texture, crucial for your Chocolate Marshmallow Swirl Cookies.

Experiment with Mix-ins: Feel free to replace semi-sweet chocolate chips with dark or white chocolate for a fun twist. Nuts or fruit can add exciting flavors too!

Chocolate Marshmallow Swirl Cookies Recipe FAQs
What type of flour should I use for the best results?
I recommend using all-purpose flour as it provides the perfect structure and texture for your cookies. If you’re looking for a gluten-free option, substitute with a gluten-free all-purpose flour blend. Make sure to check the packaging for any specific instructions regarding moisture and binding, as some blends may require adjustments.
How should I store my Chocolate Marshmallow Swirl Cookies?
Store your cookies in an airtight container at room temperature for up to 1 week. This keeps them wonderfully soft and chewy, perfect for snacking. If you’re going to enjoy them later, you can refrigerate them in a sealed container for up to 2 weeks, but allow them to come to room temperature before biting in, as they may firm up a bit when chilled.
Can I freeze Chocolate Marshmallow Swirl Cookies?
Absolutely! To freeze, place your cookies in a single layer on a baking sheet and freeze them until firm. This typically takes about 1-2 hours. Afterwards, transfer the cookies to an airtight container or sealable freezer bag, ensuring to separate layers with parchment paper to prevent sticking. They can be frozen for up to 3 months. Just thaw them at room temperature when you’re ready to enjoy!
What should I do if my cookie dough is too sticky?
If you find your cookie dough is too sticky, it may be due to an excess of moisture in the ingredients or climate conditions. You can try refrigerating the dough for about 30 minutes to help it firm up. If needed, add a bit more flour, one tablespoon at a time, mixing gently until the dough is manageable but still moist. Remember, overmixing can cause tough cookies, so fold delicately!
Are there any allergies I should consider when making these cookies?
Yes, be cautious of common allergens! These cookies contain eggs, dairy (in the butter and chocolate), and gluten (in the flour). If someone has an egg allergy, you might consider using a flaxseed egg as a substitute. Additionally, be aware of any marshmallow varieties that may contain gelatin if you have concerns about dietary restrictions for vegan or vegetarian diets. Always read labels to ensure safety for your loved ones.
