Ingredients

To create your heavenly Marshmallow Chocolate Chip Cookies, gather the following ingredients:
- 3 1/3 cups all-purpose flour (choose organic for extra quality)
- 1 1/2 teaspoons baking powder
- 1 1/4 teaspoons baking soda
- 1 teaspoon cornstarch (adds chewiness)
- 1 teaspoon kosher salt
- 1 1/4 cups unsalted butter, room temperature (using high-quality butter, like Plugra, can elevate flavor)
- 1 1/4 cups light brown sugar, packed (it gives a deeper flavor)
- 1 cup granulated sugar
- 2 large eggs, room temperature
- 2 teaspoons vanilla extract (go for pure vanilla for the best taste)
- 2 1/2 cups semi-sweet chocolate chips
- 1 jar (7 ounces) marshmallow fluff, divided (look for a brand without artificial ingredients)
Pro Tips: Make sure your butter and eggs are at room temperature for easier mixing. Also, using fresh baking soda and powder is crucial for that perfect rise!

Step-by-Step Instructions
Preheat your oven to 350°F (180°C). Line 2 large baking sheets with parchment paper for easy clean-up and to prevent sticking.
In a large bowl, whisk together the flour, baking powder, baking soda, cornstarch, and kosher salt. Set aside to allow the leavening agents to activate when mixed with wet ingredients.
Cream your butter and sugars: In the bowl of a stand mixer fitted with the paddle attachment, add the room-temperature butter, light brown sugar, and granulated sugar. Beat at medium speed for 3-5 minutes, or until the mixture is light and fluffy—this step adds air, giving structure to your cookies.
Incorporate the eggs and vanilla: Reduce mixer speed to low and add the eggs one at a time, mixing until just combined. Then, add the vanilla extract, allowing the sweet aroma to fill your kitchen.
Combine the dry and wet ingredients: Gradually add the dry mixture to the wet mixture. Mix until just combined, being careful not to overmix, resulting in tough cookies.
Fold in chocolate chips: Slowly mix in the semi-sweet chocolate chips until evenly distributed throughout the dough.
Scoop out the dough: Using a 2-tablespoon cookie scoop, drop dollops of dough onto the lined baking sheets. Flatten each dough ball into a disk using your palm. You should have about 36 cookie disks.
Add the marshmallow fluff: Taking about a tablespoon of marshmallow fluff, place it in the center of each disk. Place another disk on top and seal the edges well by pressing them together.
Bake the cookies: Place 2 stuffed cookies onto the prepared baking sheet, leaving about 4 inches of space between each. Bake for 13-14 minutes or until the edges are golden brown. They’ll look slightly underbaked in the center—that’s what you want for extra gooeyness!
Cool completely: Allow the cookies to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.

Expert Tips & Tricks
Storage: Store leftover cookies in an airtight container at room temperature for up to 4-5 days. If you want to enjoy them longer, they freeze beautifully! Just layer them between parchment paper in an airtight container or a resealable bag and freeze for up to three months.
Make-ahead instructions: You can prepare the dough in advance and freeze it! Scoop the dough, freeze the disks on a baking sheet, then transfer them to a zip-top bag. Bake from frozen, adding an extra minute or two to the baking time.
Avoid cookie mishaps: To avert common mistakes, ensure you measure your flour correctly. Avoid scooping straight from the bag, as this can lead to dry cookies. Instead, spoon it into your measuring cup and level it off.
Serving Suggestions
These Marshmallow Chocolate Chip Cookies shine on their own, but they can be paired perfectly with a glass of cold milk, vanilla ice cream, or a steaming cup of hot cocoa. For a fun presentation, arrange them on a bright platter, nestle in a few chocolate-covered marshmallows, and sprinkle some sea salt flakes on top for an impressive touch. They are perfect for birthdays, holidays, or simply as a sweet surprise for family movie night!
Variations & Substitutions
Flavor Combinations: Try adding chopped nuts like walnuts or pecans for added crunch. You could also swap in dark chocolate chips or even white chocolate for different flavor experiences.
Dietary Restrictions: For a gluten-free twist, substitute the all-purpose flour with your favorite gluten-free blend. If you need a dairy-free option, use vegan butter and dairy-free chocolate chips.
Seasonal Variations: Make them festive by adding flavored extracts like peppermint during the winter holidays or swapping the classic marshmallow fluff for seasonal flavors like pumpkin spice in the fall.
