For the Cookie Base
• All-purpose flour – Provides structure; substitute with gluten-free flour for a gluten-free option.

• Baking soda – Acts as a leavening agent, aiding in cookie rise and tenderness.
• Salt – Enhances sweetness and balances chocolate flavors.
For the Sweetness
• Unsalted butter – Contributes richness and moisture; can be replaced with vegan butter for a dairy-free version.
• Granulated sugar – Sweetens the cookies and adds to their texture.
• Brown sugar – Adds moisture and a touch of caramel flavor; can substitute with coconut sugar for a healthier option.
For Binding and Flavor
• Egg – Binds ingredients together; for vegan options, use applesauce or flaxseed meal as a substitute.
• Vanilla extract – Infuses aromatic flavor into the cookie dough.
For the Chocolatey Goodness
• Semi-sweet chocolate chips – Provide melty bursts of chocolate; consider dark or milk chocolate for varying sweetness levels.

Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies Recipe
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) while you prepare your baking sheets. Line two baking sheets with parchment paper to prevent sticking. This step ensures that your Chocolate Marshmallow Swirl Cookies will bake evenly, giving them a warm, inviting texture.
Step 2: Combine Dry Ingredients
In a medium-sized bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt until well blended. This will create a uniform mixture that contributes to the perfect chewy texture. Set this bowl aside as you move on to the butter mixture, allowing the ingredients to meld without any lumps.
Step 3: Cream Butter and Sugars
In a large mixing bowl, cream the softened unsalted butter, granulated sugar, and brown sugar together using a hand mixer or a stand mixer on medium speed. Beat for 2–3 minutes until the mixture is light and fluffy, creating a delightful base for your cookies. This step is key to achieving a rich flavor in your Chocolate Marshmallow Swirl Cookies.
Step 4: Add Egg and Vanilla
Next, beat in one egg and a splash of vanilla extract until fully incorporated into the butter-sugar mixture. Mix until the batter is smooth and creamy, ensuring that the flavors are well combined. This addition brings richness and depth, making your cookies even more irresistible.
Step 5: Mix in Dry Ingredients
Gradually add the flour mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix; you want to see streaks of flour still visible. This gentle incorporation will help keep your Chocolate Marshmallow Swirl Cookies tender and chewy, so your home will soon be filled with a delightful aroma.
Step 6: Fold in Chocolate and Marshmallows
Carefully fold in the semi-sweet chocolate chips and mini marshmallows using a spatula. Mix until they are evenly distributed throughout the dough while allowing some marshmallow swirls to remain visible. These marshmallows will provide gooey surprises in your cookies, enhancing the flavor profile of your freshly baked treats.
Step 7: Scoop the Dough
Using a cookie scoop or tablespoon, place rounded dollops of the cookie dough onto your prepared baking sheets. Make sure to leave about 2 inches of space between each scoop to allow for spreading during baking. It’s a fun step that ensures each Chocolate Marshmallow Swirl Cookie is perfectly portioned!
Step 8: Bake Until Perfect
Bake the cookies in your preheated oven for 8–10 minutes. Keep an eye on them; the edges should be set, while the centers will remain softly baked. You’ll see the marshmallows begin to caramelize slightly—this is a great visual cue indicating they are ready to emerge from the oven.
Step 9: Cool and Transfer
Once baked, remove the cookie sheets from the oven and let the cookies cool on the sheets for about 5 minutes. This allows them to firm up while maintaining a delicate chewiness. After cooling, carefully transfer the Chocolate Marshmallow Swirl Cookies to a wire rack to cool completely, letting their mouthwatering aroma fill your kitchen.
Make Ahead Options
These Chocolate Marshmallow Swirl Cookies are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the cookie dough up to 3 days in advance and store it in an airtight container in the refrigerator. To maintain the dough’s quality and prevent browning, cover it tightly with plastic wrap. When you’re ready to bake, simply scoop the dough onto your baking sheets and let it sit at room temperature for about 15-20 minutes before baking. This way, you’ll enjoy freshly baked cookies with gooey marshmallow swirls, all with minimal effort on your busy day!
Expert Tips for the Best Chocolate Marshmallow Swirl Cookies
Softened Butter: Ensure your butter is at room temperature for easy creaming, resulting in light and fluffy cookies.
Avoid Overmixing: Gently combine the dry ingredients with the wet mixture to keep the cookies tender. Too much mixing can lead to tough cookies.
Watch for Caramelization: Keep an eye on your cookies while baking; marshmallows can caramelize quickly, adding an extra layer of flavor when perfectly toasted.
Cooling Time: Allow cookies to cool briefly on the baking sheet before transferring to a wire rack. This helps them set and stay chewy.
Experiment with Flavors: Try using different chocolate types or flavored extracts to customize your Chocolate Marshmallow Swirl Cookies recipe for your taste!

Chocolate Marshmallow Swirl Cookies Recipe FAQs
How do I choose the best chocolate for my cookies?
Absolutely! I recommend using semi-sweet chocolate chips for a perfect balance of sweetness and richness. You could also opt for dark chocolate for a more indulgent flavor or milk chocolate if you prefer a sweeter treat. Get creative with your favorite types!
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 1 week. Make sure they are completely cooled before sealing, as any moisture can impact their chewiness. I often add a slice of bread in the container; it helps maintain moisture while the cookies stay soft!
Can I freeze these cookies?
Yes, indeed! To freeze, stack your cooled Chocolate Marshmallow Swirl Cookies between layers of parchment paper in an airtight, freezer-safe container. They can be frozen for up to 3 months. When you’re ready to indulge, simply thaw them at room temperature or reheat them in the microwave for a few seconds to restore that gooeyness.
What should I do if my cookies spread too much while baking?
If your cookies spread excessively, it might be due to melted butter or too much sugar. Ensure that your butter is softened, not melted, before creaming with the sugars. Also, check the measurement of ingredients, particularly the flour, as too little can lead to overly spread cookies. If time allows, chilling the dough for about 30 minutes before baking can help them hold their shape better.
Can my pets enjoy these cookies too?
No, it’s best to keep these cookies away from your furry friends. Ingredients like chocolate and certain sweeteners can be harmful to pets. It’s always wise to double-check that treats intended for humans are safe for animals before sharing.
