What is a Fluffernutter?

A fluffernutter, or as we New Englandahs pronounce it, “fluffahnuttah”, is a sandwich made with peanut butter and marshmallow fluff on white bread. Some variations include additions like sliced fruit or chocolate but I love it in its simple original form.

My love for fluffernutters started in childhood and inspired this cookie recipe. The creamy layer of fluff between two peanut butter cookies makes these cookies taste extra impressive. No one suspects how easy Fluffernutter Cookies are to make!

How to Make Fluffernutter Sandwich Cookies

Start by making a simple peanut butter cookie dough. Next, beat together the sugars with shortening and vanilla. Then, mix in the eggs, peanut butter and the dry ingredients.

Shape the dough into balls and place them on a baking sheet. Use the tines of a fork to press a criss-cross pattern onto each cookie.

Bake them for about 10 minutes or until golden brown. When the cookies are cooled spoon a little marshmallow fluff onto the flat side of half the cookies. Finally, top them with the remaining cookies and enjoy!

Can I freeze these cookies?

Yes, these cookies are freezer friendly! Store the sandwich cookies in an airtight container or freezer bags. They will stay good in the freezer for about 3 months.

The marshmallow fluff won’t become solid in the freezer but it will stay fresh until you’re ready to enjoy your fluffernutter cookies.

Then just thaw on the counter or in the refrigerator before you’re ready to enjoy.
