Stuffed Fluffernutter Cookies

These cookies are TO die for. They're just slightly crisp on the edges, and the rest of the cookie is oh so soft. Let's not forget the chewy marshmallow strewn throughout the center, and bits of the peanut butter provide an extra punch of flavor.

Adam asks me every other day to make them. Adam's brother was in town after a test batch and he ate eight of them in about 12 hours. These cookies are not small, by the way. My sister also demanded the recipe before this publish because she couldn't wait to make them.

Do you know what a fluffernutter is and did you grow up eating this as a child? If you're lost here, a classic fluffernutter is a sandwich made from squishy white bread, filled with peanut butter and marshmallow fluff. If you had this tub in your cupboard, welcome to the fluffernutter club.

It is THE best treat - my mom still makes them occasionally for her and my dad. So cute. I can also distinctly remember spreading dabs of peanut butter and fluff on saltine crackers at my grandparents house.

A perfect combination, these cookies are made with creamy peanut butter (Jif, Skippy, Peter Pan, not natural peanut butters) and a whole marshmallow rather than marshmallow fluff. This is simply because a stuffed cookie is easier to assemble around a more stiff ingredient! That's also why the peanut butter gets frozen before going into the cookies. Check the FAQ section below for more information on marshmallows vs marshmallow fluff.

Start by adding 12 heaping teaspoon dollops of peanut butter onto a parchment lined plate and freeze. Freezing these makes life SO much easier when stuffing the cookies. Use your finger or a butter knife to get the peanut butter out of the teaspoon. If the ¼ cup does not yield the 12 teaspoons, use additional peanut butter to get to 12. It should be very close.

While the peanut butter is in the freezer, make the cookie dough. Sift or whisk together the flour and baking soda and set aside. Cream together the butter and peanut butter, then add the sugars and beat on medium speed for about two minutes until it becomes lighter and fluffier. This can be done with a stand mixer (paddle attachment) or a hand mixer.

Add in the egg, salt and vanilla, then scrape down the sides and add the flour. Mix on low until it's just incorporated.

Line two standard baking sheets with parchment paper and gather 12 marshmallows. Rip a section of 3-4 frozen peanut butter dollops off of the plate - it's best to work in batches so the peanut butter stays as hard as possible while assembling the cookies.

Remove three even tablespoons (~60g) of dough and press it between the palms of your hands until it's flat and even. Place one dollop of peanut butter in the center, then lay a marshmallow (on its long side) on top.

Work the dough upwards and around the top of the marshmallow until it’s completely sealed. The dough may crack in some places - just gently push it together with your thumbs as best as possible. Place the ball seam side down on the cookie sheet and stud with peanut butter chips (optional).

Repeat the process until you have 12 cookies. Evenly space them out between the two cookie sheets, 6 per sheet. Bake one sheet at a time in a preheated 350℉ oven in the middle rack for 9-11 minutes. The edges and tops will look barely brown, so take care not to overcook them!

Remember, it's just a small amount of dough since it's been flattened out, so it doesn't need much time to fully cook. They will still look sightly puffy, but will flatten out while cooling. The marshmallow should still be gooey - if it has disintegrated, they're likely overcooked.

Immediately upon removing the cookies from the oven, use the tines of a fork to push together any bulging parts of the cookie into an even circle. Top with flaky salt if you have some! Allow the cookies to cool completely on the pan. Once cool, a spatula may be needed to lift off some sticky marshmallow pieces when transferring to a plate or storage container.

Not in this recipe! This is for a couple of reasons:

• The cookie dough needs the structure of the marshmallow to completely wrap around. Fluff is too soft to turn this into a stuffed cookie (at least, a non messy stuffed cookie).
• The marshmallow takes longer to melt which gives the cookie time to cook before "cracking" open to show the gooey marshmallow.

Marshmallows and marshmallow fluff are almost identical in terms of ingredients. Both of these contain egg whites, sugar syrups, and vanilla. The only notable difference is that marshmallows have gelatin added, which is why they have a firmer texture. There is also a bit of a difference in the mixing process that gives fluff an airier texture than a marshmallow. BUT, same base ingredients.

Yes. While it is recommended to use normal-sized marshmallows to make the Stuffed Fluffernutter Cookies, if you only have mini marshmallows available, use 4-5 per cookie.
