Ingredients
For these delectable Marshmallow Chocolate Chip Cookies, you’ll need the following ingredients:
3 1/3 cups all-purpose flour
- For best results, use a high-quality brand, like King Arthur Flour.
1 1/2 teaspoons baking powder
- Ensure it’s fresh for the best rise!
1 1/4 teaspoons baking soda
- Helps balance the density of the cookie.
1 teaspoon cornstarch
- For extra chewiness!
1 teaspoon kosher salt
- Balances the sweetness beautifully.
1 1/4 cups unsalted butter, room temperature
- Always use unsalted for better control over flavor.
1 1/4 cups light brown sugar, packed
- Adds moisture and a caramel-like flavor!
1 cup granulated sugar
- For sweetness and to help achieve that crispy edge.
2 large eggs, room temperature
- Room temp eggs mix better!
2 teaspoons vanilla extract
- Always opt for pure vanilla extract for deeper flavor.
2 1/2 cups semi-sweet chocolate chips
- I love Ghirardelli chocolate chips for their rich taste!
1 jar marshmallow fluff, divided
- Don’t skimp on the marshmallow fluff—it’s the star of the show!
Preparation Notes
- Ensure your butter and eggs are at room temperature. This will help the ingredients blend more evenly, leading to a better texture.
- If you’re looking for alternatives, try using coconut oil instead of butter for a dairy-free version, or swap the chocolate for dark chocolate for a richer flavor.

Step-By-Step Instructions
1. Preheat and Prepare:
Preheat your oven to 350°F (175°C) and line two large baking sheets with parchment paper.
2. Mix Dry Ingredients:
In a large bowl, whisk together the flour, baking powder, baking soda, cornstarch, and salt. This ensures even distribution of the leavening agents.
Chef’s Tip: Sifting some of the dry ingredients can improve the overall texture of your cookies!
3. Cream Butter & Sugars:
In a stand mixer, cream together the room temperature butter, light brown sugar, and granulated sugar at medium speed until light and fluffy—about 3-4 minutes.
4. Add Eggs and Vanilla:
Reduce the speed to low and add the eggs one at a time, mixing just until combined. Then, mix in the vanilla extract.
5. Combine Wet & Dry Ingredients:
Gradually add the dry ingredients to the wet mixture, mixing until just combined. Avoid over-mixing—this can lead to tougher cookies.
6. Fold in Chocolate Chips:
Gently fold in the chocolate chips with a spatula or wooden spoon.
7. Shape the Cookies:
Using a cookie scoop or tablespoon, drop balls of dough onto the prepared baking sheets. Flatten each dough ball slightly, then create a small indentation in the center.
8. Add Marshmallow Fluff:
Scoop a generous teaspoon of marshmallow fluff into the center of each flattened dough ball. Don’t hold back here!
9. Seal with Dough:
Top each filled dough ball with a second dough circle and seal the edges carefully to seal in the marshmallow.
10. Bake:
Bake for 13-14 minutes, or until the cookies are golden brown around the edges. They will look a bit soft in the center, but that’s perfectly fine!
11. Cool:
Allow cookies to cool completely on the baking sheets before serving to allow the marshmallow fluff to set slightly.
Common Mistake to Avoid: Don’t overbake! Cookies will continue to firm up as they cool, and we want those soft centers to remain gooey.

Expert Tips & Tricks
Storage Recommendations: Store your cookies in an airtight container at room temperature for up to one week. For longer freshness, refrigerate them.
Make-Ahead: You can prepare the cookie dough ahead of time and refrigerate it for up to 3 days or freeze it for up to 3 months. Just allow it to thaw in the fridge overnight when you are ready to bake.
Perfect Fillings: For a fun twist, consider using different fillings like Nutella or peanut butter instead of marshmallow fluff. You can also mix in some crushed nuts or oats for added texture.
Even Baking: Rotate your baking sheets halfway through the bake time to ensure even baking, especially if your oven has hot spots.
Troubleshooting: If your cookies spread too much, try chilling the dough for 15-20 minutes before baking to help them hold their shape.
Reheating: To revive the gooeyness of these cookies, pop them in the microwave for just a few seconds before enjoying.
