How to Make Fluffernutter Cookies
Preheat your oven to 350°F and prepare two large baking sheets. Line them with parchment paper to ensure easy cookie removal and a nice, even bake.
Mix the peanut butter, unsalted butter, and brown sugar in a large bowl. Using a hand mixer, combine until the mixture is smooth and creamy about 2-3 minutes will do the trick!
Add the egg and vanilla extract to the bowl. Mix these in until everything is beautifully combined, which should take about 30 seconds.
Incorporate the dry ingredients by adding flour, cornstarch, and kosher salt. Stir those in gently until just combined; be careful not to overmix (30 seconds to 1 minute is perfect).
Scoop the dough onto your lined baking sheets using a 2-tablespoon cookie scoop. Then, flatten each dough ball gently into a 3-inch disk for even baking.
Fill the centers! Using two spoons, add about 1 tablespoon of marshmallow fluff to the middle of each disk.
Wrap the dough around the marshmallow fluff, ensuring it s completely covered, and then form it into a ball. Place these delightful little dough balls on the baking sheets.
Bake the cookies for 10-12 minutes, watching closely for that golden edge. You want the marshmallow to stay gooey without burning, so keep an eye on them!
Cool the cookies for 10-15 minutes before serving to allow them to set properly and enjoy that warm, fluffy goodness.
Optional: Serve with a drizzle of chocolate sauce for an extra treat.
