Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven is warming up, line two baking sheets with parchment paper to ensure easy cookie removal later. This step sets the stage for baking the perfect Chocolate Marshmallow Swirl Cookies, so keep an eye on the temperature!

Step 2: Mix the Dry Ingredients
In a medium-sized bowl, whisk together 1 ¾ cups of all-purpose flour, ½ cup of unsweetened cocoa powder, 1 teaspoon of baking soda, and ½ teaspoon of salt. This dry mix will create a flavorful base for your cookies. Ensure there are no lumps in the cocoa powder, which could affect the texture, and set it aside for later use.

Step 3: Cream the Butters and Sugars
In a large mixing bowl, cream together ½ cup of softened unsalted butter, ½ cup of granulated sugar, and ½ cup of brown sugar using an electric mixer on medium speed. Beat for about 2-3 minutes until the mixture becomes light and fluffy. This step is crucial for achieving a tender texture in your Chocolate Marshmallow Swirl Cookies.

Step 4: Incorporate Egg and Vanilla
Next, add in 1 large egg and 1 teaspoon of pure vanilla extract to the creamy mixture, beating until fully combined. Remember to scrape down the sides of the bowl as necessary to ensure everything is well blended. This addition brings richness and flavor, immersing your cookie dough with delightful taste.

Step 5: Combine Dry and Wet Ingredients
Gradually pour the dry ingredient mixture into the wet ingredients, mixing on low speed until just combined. Be careful not to overmix, as it can lead to dense cookies. The dough should come together nicely, forming a soft, slightly sticky consistency that’s characteristic of Chocolate Marshmallow Swirl Cookies.

Step 6: Add Chocolate and Marshmallows
Gently fold in 1 cup of semi-sweet chocolate chips and 1 cup of mini marshmallows into the dough using a wooden spoon or spatula. This step ensures every cookie is filled with gooey goodness. The luscious chocolate and sweet marshmallows create that signature taste and texture we all love in these cookies!

Step 7: Scoop the Dough
Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, leaving about 2 inches of space between each cookie. This will allow the cookies to spread without merging together. Aim for about 12 cookies per baking sheet, making sure they are evenly spaced for baking.

Step 8: Bake the Cookies
Place the cookie sheets in the oven and bake for 8-10 minutes, or until the edges are set and the centers still look slightly soft. The marshmallows may puff up a bit, giving a beautiful visual cue of doneness. Keep a close eye on them to prevent over-baking!

Step 9: Cool on Baking Sheets
Once baked, remove the cookies from the oven and let them cool on the baking sheets for about 5 minutes. This allows them to firm up slightly while still warm. Then, use a spatula to transfer the cookies to a wire rack. Let them cool completely for the best texture and flavor in your Chocolate Marshmallow Swirl Cookies.

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 fresh and maintains their delicious gooey texture.

Fridge: For longer freshness, you can refrigerate the cookies for up to 2 weeks. Place them in a sealed container to prevent them from drying out.

Freezer: Freeze cookies in a single layer on a baking sheet for 1–2 hours, then transfer to a freezer-safe bag or container. They can be frozen for up to 3 months!

Reheating: To enjoy the cookies warm, reheat in the microwave for about 10-15 seconds, or warm them in the oven at 350°F (175°C) for a few minutes until heated through, allowing the marshmallow to get all melty again!

Expert Tips for Chocolate Marshmallow Swirl Cookies

Measure Ingredients Accurately: Ensure precise measurements to maintain the perfect balance of flavors and textures in your Chocolate Marshmallow Swirl Cookies.
Avoid Overmixing: Gently combine the wet and dry ingredients until just incorporated. Overmixing can lead to tough cookies instead of the desired tender bite.
Monitor Baking Time: Keep a close watch while baking. The edges should be set but the centers slightly soft, ensuring a chewy texture and gooey marshmallow surprise.
Use Softened Butter: Make sure your unsalted butter is at room temperature for easy creaming. This step is crucial for a light and fluffy cookie dough.
Chill if Needed: If your dough seems too soft, chilling it for 30 minutes can help the cookies hold their shape during baking, especially with the gooey marshmallows.

Make Ahead Options

These Chocolate Marshmallow Swirl Cookies are perfect for busy home cooks looking to save time! You can prepare the cookie dough in advance and refrigerate it for up to 3 days. Simply mix the dough as instructed, then wrap it tightly in plastic wrap or place it in an airtight container. This helps maintain the cookies’ freshness and prevents the dough from drying out. When you’re ready to bake, scoop the chilled dough onto a baking sheet and let it sit at room temperature for about 10 minutes before baking. This way, you’ll enjoy warm, gooey cookies fresh from the oven with minimal effort, just as delicious as if you made them on the spot!

Chocolate Marshmallow Swirl Cookies Recipe FAQs

What type of flour should I use for the best texture?
Absolutely! All-purpose flour is best for these cookies as it provides structure. However, if you need a gluten-free option, you can substitute with a 1-to-1 gluten-free flour blend. Just make sure it has xanthan gum in the mix for added stability.

How long can I store these cookies?
You can store your Chocolate Marshmallow Swirl Cookies in an airtight container at room temperature for up to 1 week. If you want to keep them fresher longer, they can last in the fridge for about 2 weeks. Just do note to seal them well to avoid drying out.

Can I freeze the cookie dough?
Yes, you can freeze the cookie dough! Scoop the dough into balls and place them on a baking sheet in a single layer to freeze for 1-2 hours. Once solid, transfer them to a freezer-safe bag. They’ll keep well for up to 3 months. When ready to bake, no need to thaw; just add a couple of extra minutes to the baking time!

What should I do if my cookies spread too much during baking?
Very! If you notice that your cookies spread too much, it’s possible that the butter was too soft when mixed or the dough was not chilled enough. To troubleshoot this, try chilling the dough for 30 minutes before scooping and baking. That extra chill can help the cookies maintain their shape and prevent excess spreading in the oven!

Are these cookies safe for those with allergies?
Though delicious, Chocolate Marshmallow Swirl Cookies contain common allergens like gluten, dairy, and eggs. If you’re baking for someone with allergies, you can make adjustments: try using gluten-free flour, coconut oil instead of butter, and a flax egg in place of a regular egg. Always check the labels on chocolate chips and marshmallows, as some brands may contain allergens.
