Step‑by‑Step Instructions for Chocolate Marshmallow Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, line a baking tray with parchment paper to prevent the cookies from sticking. This step is essential for achieving that perfectly baked Chocolate Marshmallow Cookies, setting the stage for a deliciously gooey treat.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, Dutch processed cocoa powder, baking soda, and salt until thoroughly combined. This mixture should show an even consistency and a rich chocolate color. Once well blended, set the bowl aside, allowing the dry ingredients to infuse your cookies with flavor.
Step 3: Combine the Wet Ingredients
In a large bowl, whisk the melted and cooled unsalted butter with the light brown and granulated sugars until smooth and creamy. Next, add in the room-temperature large egg and vanilla extract, mixing until fully incorporated. This mixture should be glossy and rich, ensuring a decadent base for your Chocolate Marshmallow Cookies.
Step 4: Blend the Mixtures
Gradually incorporate the dry ingredients into the wet mixture, stirring gently until just blended. Be careful not to overmix; you want to keep that fudgy texture intact! The resulting dough should be thick and slightly sticky, full of alluring chocolate aroma.
Step 5: Fold in the Marshmallows
Gently fold in the mini marshmallows into the cookie dough, being careful not to crush them. This step is crucial as it will create the gooey center of your Chocolate Marshmallow Cookies. Aim for an even distribution to ensure every cookie will surprise you with that melting marshmallow!
Step 6: Form the Cookie Dough Balls
Using a tablespoon, scoop out the dough and roll it into balls. Place them on the prepared baking tray, making sure to space them about 2 inches apart. This will allow the cookies to spread slightly as they bake, creating deliciously thick Chocolate Marshmallow Cookies that are irresistible.
Step 7: Bake the Cookies
Place the tray in the preheated oven and bake for 8-10 minutes, or until the edges are set and the tops show slight cracks. Keep an eye on them towards the end of the baking time, as you want them to remain soft and chewy in the middle, showcasing that mouthwatering marshmallow center.
Step 8: Cool and Enjoy
After they have baked, allow the cookies to cool on the tray for about 10-15 minutes. This cooling time will help them set without falling apart. Using a spatula, carefully transfer the cookies to a wire rack to cool completely, making sure to let the tempting aroma of your Chocolate Marshmallow Cookies fill the kitchen!

Expert Tips for Chocolate Marshmallow Cookies
-
Weigh Ingredients: To prevent dry cookies, accurately weigh your flour and cocoa powder instead of using volumetric measurements.
-
Chill the Dough: If the cookie dough feels too sticky, refrigerate it for 10 minutes before shaping into balls to make handling easier.
-
Use Parchment Paper: Always line your baking tray with parchment paper to ensure the cookies release easily and maintain their gooey center.
-
Monitor Baking Time: Keep an eye on the cookies during the last few minutes of baking; you want the edges firm while the center remains gooey for that fudgy Chocolate Marshmallow Cookies experience.
-
Create Shapes: For more defined cookie shapes, use a cookie cutter to reshape the cookies right after baking.
-
Storage Matters: Store your Chocolate Marshmallow Cookies in an airtight container for optimal freshness, or freeze them for up to three months for later enjoyment.
Make Ahead Options
These Chocolate Marshmallow Cookies are perfect for busy home cooks looking to save time while still indulging in homemade goodness! You can prepare the cookie dough up to 24 hours in advance—just scoop the dough into balls and place them on a baking tray lined with parchment paper. Cover the tray with plastic wrap and refrigerate. When you’re ready to bake, simply take them out and let them sit at room temperature for about 10 minutes before popping them in the oven. If you prefer, you can also freeze the dough balls for up to 3 months; just bake from frozen, adding a minute or two to the baking time. This way, you’ll have those irresistible Chocolate Marshmallow Cookies ready whenever a craving strikes, all while maintaining that delicious chewy texture and gooey center!

Chocolate Marshmallow Cookies Recipe FAQs
What is the best way to select ripe ingredients?
Absolutely! When selecting ingredients, ensure your butter is unsalted and has a rich yellow color, which indicates freshness. For the egg, you want it to feel heavy for its size, and a room-temperature egg will mix better into the dough. As for the mini marshmallows, look for ones that are soft without any hard edges or dark spots.
How should I store my Chocolate Marshmallow Cookies?
To keep your cookies fresh, store them in an airtight container at room temperature for about 4-5 days. If you prefer a firmer texture, they can also be refrigerated for up to a week, just remember to wrap them well to prevent any odors from seeping in.
Can I freeze Chocolate Marshmallow Cookies, and if so, how?
Very much! To freeze your cookies, allow them to cool completely first. Then, arrange them in a single layer on a baking sheet and freeze until firm. Once frozen, transfer them to an airtight container or freezer bag—layering parchment paper between cookies can help prevent sticking. They can be stored in the freezer for up to 3 months.
What should I do if my cookie dough is too sticky?
If your dough is sticking to your hands or work surface, don’t worry! Simply refrigerate it for about 10 minutes. This makes it easier to handle and shape into balls, giving you those perfect Chocolate Marshmallow Cookies you’re aiming for.
Are there any dietary considerations with this recipe?
Absolutely! If you’re making these cookies for someone with dietary restrictions, you can use gluten-free flour as a substitute for all-purpose flour. Additionally, vegan marshmallows can replace regular ones if you want to go fully plant-based. Always check ingredient labels for potential allergens, especially concerning the sugars and flavorings you choose.
What can I do if my cookies don’t turn out fudgy?
Not to worry! If your cookies turn out drier than expected, you may have overmixed the dough or baked them for too long. Always ensure you bake them for the recommended time, checking them when they look slightly underdone, as they will continue to firm up. If you’re looking for a fudgier cookie, consider adding an extra egg yolk next time for added moisture and richness.
