Step‑by‑Step Instructions for Chocolate Chip Marshmallow Cookies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it heats, prepare a baking sheet by lining it with parchment paper. This will prevent sticking and make cleanup a breeze. You should see the paper lie flat, ready to cradle your freshly baked Chocolate Chip Marshmallow Cookies.
Step 2: Mix Wet Ingredients
In a large mixing bowl, whisk together melted unsalted butter and brown sugar until the mixture is smooth and well combined, about 1-2 minutes. You want it to be glossy and slightly thicker. Next, add in the room temperature egg and vanilla extract, whisking vigorously for another 2-3 minutes until the batter looks lighter in color and fluffy.
Step 3: Combine Dry Ingredients
Now, gently fold in the all-purpose flour, baking soda, salt, and cornstarch. Make sure you don’t overmix—stop when just combined, and you see no dry streaks. The goal is a slightly thick cookie dough that will hold its shape, ready for the star of the show—your semi-sweet chocolate chips. Fold these in until evenly distributed throughout the dough.
Step 4: Form Cookie Dough Balls
Using a 2-tablespoon cookie scoop or your hands, portion out the cookie dough, rolling it into balls. Flatten each ball slightly into a disk shape, creating an inviting spot in the center for the delicious marshmallow fluff. If your marshmallow fluff is frozen, it will be easier to handle; make sure to measure one tablespoon per cookie.
Step 5: Assemble the Cookies
Place one tablespoon of marshmallow fluff onto the center of each flattened dough disk. Gently place another flattened disk on top, sealing the edges carefully to encase the fluff. Ensure there are no gaps so that it doesn’t ooze out during baking. This step is crucial for those delightful ooey-gooey Chocolate Chip Marshmallow Cookies.
Step 6: Sprinkle and Bake
Before placing the cookies in the oven, sprinkle flaked Kosher salt over the top of each to enhance the sweetness balance. Bake in your preheated oven for 8-10 minutes or until the edges are golden brown. Keep an eye on them; the center should look slightly soft but set to ensure the perfect chewy texture.
Step 7: Cooling Time
Once baked, remove the baking sheet from the oven and let the cookies cool on the sheet for 10 minutes. This allows them to firm up while the marshmallow fluff cools slightly but remains deliciously gooey. Afterward, carefully transfer them to a wire rack to cool completely, allowing you to fully enjoy the delightful texture of your Chocolate Chip Marshmallow Cookies.

Make Ahead Options
These Chocolate Chip Marshmallow Cookies are perfect for busy weeknights when you want to save time without sacrificing flavor! You can prepare the cookie dough up to 24 hours in advance—simply store it tightly wrapped in plastic wrap in the refrigerator. You can also form the cookie dough balls, filling them with frozen marshmallow fluff and refrigerating them for even easier baking later. When you're ready to bake, preheat your oven and place the chilled dough on a parchment-lined baking sheet, then simply bake for 8-10 minutes until golden. This way, you’ll have fresh, delicious cookies ready to enjoy with minimal effort, just as delightful as if they were baked on the spot!

Expert Tips for Chocolate Chip Marshmallow Cookies
-
Proper Butter Cooling: Allow the melted butter to cool slightly before mixing; this prevents the eggs from cooking and ensures a smooth batter.
-
Don’t Overmix: Gently fold the dry ingredients into the wet; overmixing can lead to tough cookies. Aim for just combined and avoid dry streaks.
-
Marshmallow Placement: Make sure the marshmallow fluff is in the center and fully sealed in the cookie dough; this guarantees that the filling stays inside while baking.
-
Spacing is Key: Keep cookies at least 2 inches apart on the baking sheet to allow for minor spreading, despite their no-chill nature.
-
Adjust for Size: For smaller cookies, halve the dough and fluff amounts but remember to adjust the baking time for a perfect bake.
These Chocolate Chip Marshmallow Cookies are delightful with minimal effort!

Chocolate Chip Marshmallow Cookies Recipe FAQs
How do I choose the right marshmallow fluff?
Absolutely! When selecting marshmallow fluff, look for a brand that has a smooth texture and a pure white color, which usually indicates freshness. Avoid any containers with dark spots or signs of separation, as this may affect the final taste and texture of your cookies.
What’s the best way to store these cookies?
To keep your Chocolate Chip Marshmallow Cookies fresh, store them in an airtight container at room temperature for up to a week. You can also refrigerate them to extend their freshness for up to two weeks. This can actually enhance their flavors, making each bite even more delightful!
Can I freeze these cookies for later?
Yes, you can! To freeze your cookies, individually wrap each one in plastic wrap and place them in a labeled freezer bag. They’ll stay fresh for up to three months. When you're ready to enjoy a cookie, simply warm it in the microwave for about 10-15 seconds to revive that gooey marshmallow filling!
What if my cookie dough is too sticky?
Very! If you find your cookie dough is a bit too sticky, this may be due to variations in flour measurement or overmixing. To help, you can add a tablespoon of flour at a time until the dough is manageable. Make sure you’re measuring flour correctly; spoon it into your measuring cup and level it off!
Can I use alternative ingredients for allergies?
Definitely! If you need to cater to allergies, you can substitute the all-purpose flour with a gluten-free blend. Likewise, if dairy is a concern, look for dairy-free butter. Just remember to check all labels for potential allergens, especially with chocolate chips and marshmallow fluff.
How can I get the cookies to hold their shape?
For perfectly shaped cookies, shape your dough balls before baking, as they won’t spread during the cooking process. Make sure to create a small indentation for the marshmallow fluff and seal it well so it doesn’t leak out when baking. Proper spacing on the baking sheet is essential, too—space those cookies about 2 inches apart!
