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, line two baking sheets with parchment paper, ensuring they are ready for the delicious Chocolate Marshmallow Swirl Cookies that are about to come your way. This prep step is crucial for easy cleanup and the perfect baking environment.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt until well combined. This step is important to evenly distribute the dry ingredients, preventing clumps and ensuring your cookies rise beautifully. Set the bowl aside, letting the dry ingredients mingle while you tackle the next step.
Step 3: Cream Butter and Sugars
In a large mixing bowl, cream the softened unsalted butter together with granulated sugar and brown sugar for about 2-3 minutes until the mixture is light and fluffy. You’ll know it’s ready when it appears pale and aerated, an essential stage for creating tender Chocolate Marshmallow Swirl Cookies that melt in your mouth.
Step 4: Incorporate Egg and Vanilla
Beat in the egg and vanilla extract into the creamed mixture until fully incorporated. Take a moment to scrape down the sides of the bowl to ensure every bit of goodness is included. The warm aroma of vanilla will make your kitchen feel inviting as this mixture becomes rich and smooth.
Step 5: Combine Wet and Dry Mixtures
Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Avoid overmixing to keep your cookies soft and chewy. At this point, you’ll notice the dough forming, a lovely chocolate color hinting at the treat’s deliciousness that’s heading your way.
Step 6: Fold in Chocolate Chips and Marshmallows
Gently fold in the semi-sweet chocolate chips and mini marshmallows, along with the marshmallow fluff if using. This step creates that delightful swirl effect, blending chunks of chocolate and gooey marshmallows throughout the dough. The mixture should look decadent and inviting with pockets of sweetness.
Step 7: Scoop the Dough
Using a spoon or cookie scoop, portion the dough onto the prepared baking sheets, leaving about 2 inches between each cookie. This spacing is vital for allowing the Chocolate Marshmallow Swirl Cookies to spread evenly while baking, ensuring they’ve got room to puff up and form their delightful shape.
Step 8: Bake the Cookies
Place the baking sheets in the preheated oven and bake for 8-10 minutes, or until the edges are set but the centers remain soft. Keep an eye on them; the cookies should look slightly puffy and cracked on top. This visual cue indicates they are perfectly baked yet still gooey inside.
Step 9: Cool the Cookies
Once baked, remove the cookies from the oven and allow them to cool on the baking sheets for about 5 minutes. This initial cooling time helps them set so that they hold their shape as you transfer them to a wire rack. Enjoy the delightful aroma filling your kitchen!
Step 10: Transfer and Enjoy
Carefully transfer the cookies to a wire rack to cool completely. This final step ensures they reach that perfect texture. Once cooled, these Chocolate Marshmallow Swirl Cookies are ready to be enjoyed—perfect with a glass of milk or your favorite cozy drink!

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 to keep them soft and fresh.
Freezer: For longer storage, freeze cookies in a single layer on a parchment-lined baking sheet until firm, then transfer to an airtight container. They can be frozen for up to 3 months.
Reheating: To enjoy frozen cookies, simply thaw at room temperature or warm them in the oven at 350°F (175°C) for 5-7 minutes for a freshly baked taste.
Pre-Baking Storage: You can also freeze the cookie dough before baking. Scoop the dough onto a baking sheet, freeze until firm, then transfer to a container and store for up to 3 months.
Expert Tips for Chocolate Marshmallow Swirl Cookies
• Butter Temperature: Ensure the unsalted butter is properly softened, about 65°F, for effective creaming, which is essential for the tender texture of your cookies.
• Avoid Overmixing: Mix the dry ingredients into the wet mixture just until combined. Overmixing can lead to tougher Chocolate Marshmallow Swirl Cookies instead of the desired softness.
• Watch the Baking Time: Keep a close eye on your cookies as they bake; they should look slightly puffy and cracked on top. This indicates they are done but still gooey at the center.
• Use Parchment Paper: Line your baking sheets with parchment paper to prevent sticking and to ensure a clean release, resulting in perfectly shaped cookies.
• Storage Tip: Store the cookies in an airtight container at room temperature for up to one week, or freeze them for up to three months for delightful treats anytime!
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, simply cover it tightly with plastic wrap and refrigerate. The mini marshmallows may tend to firm up slightly in the fridge, but they’ll soften back during baking for that gooey center you love. If you’d like to get even further ahead, you can freeze the formed dough balls for up to 3 months; just scoop and freeze on a baking sheet, then transfer to an airtight container. When you’re ready to bake, simply place the frozen dough on a baking sheet and add a couple of extra minutes to the baking time for delicious, freshly baked Chocolate Marshmallow Swirl Cookies with minimal effort!

Chocolate Marshmallow Swirl Cookies Recipe FAQs
What should I look for when selecting marshmallows?
Absolutely! When choosing mini marshmallows, look for ones that are soft and fluffy, with no dark spots or signs of hardening. Fresh marshmallows will create that delightful gooeyness in your cookies. If they look hard or have been open for a while, it’s best to opt for a new bag.
How should I store my Chocolate Marshmallow Swirl Cookies?
To keep your cookies fresh, store them in an airtight container at room temperature for up to one week. If you want to enjoy them longer, freeze them as mentioned in the storage section. It helps to layer the cookies between pieces of parchment paper to prevent sticking and keep their shape.
Can I freeze the cookie dough before baking?
Absolutely! To freeze the dough, scoop it onto a baking sheet and place it in the freezer until the balls are firm. Once set, transfer the dough balls to an airtight container or a zip-top bag and store them for up to three months. When you’re ready to bake, simply place them on a baking sheet and add a couple of extra minutes to the baking time if baking from frozen.
What if my cookies come out too flat?
Very! If your cookies are flattening out too much, it may be due to the butter being too soft or melted. Always use softened butter—around 65°F—rather than melted butter. Also, ensure you’re not overmixing your dough once the dry ingredients are added. This can cause excess gluten formation, leading to flatter cookies.
Are there any allergy considerations with this recipe?
Yes! This Chocolate Marshmallow Swirl Cookies recipe contains common allergens such as gluten (from the flour), dairy (from the butter), and eggs. For a gluten-free version, substitute all-purpose flour with a gluten-free baking blend. If you’re concerned about dairy, you can use dairy-free butter and egg substitutes.
How do I know when the cookies are properly baked?
You’ll know the cookies are ready when the edges are set, but the centers still look slightly soft and puffy. The tops should have a slight crackle appearance. If they start to look too firm or over-baked, it may lead to a crunchy texture instead of that lovely chewy base that we adore!
