What is Fluffernutter?

First, you might be wondering what fluffernutter actually is!

A fluffernutter sandwich is an iconic New England classic, made with peanut butter and marshmallow creme. It’s traditionally served on white bread.

There are variations, of course. You can substitute with wheat bread, add bananas, and so much more. The sandwich has a long history in the region and the flavors are perfectly captured in this cookie!

What is Marshmallow Creme?

Marshmallow creme is similar in flavor to a traditional solid marshmallow. However, it’s more of a spread, and sold in a jar!

How to Make these Fluffernutter Cookies

  • In a saucepan on medium, melt butter and chocolate, stirring until smooth. Remove from heat and mix brown sugar, eggs and vanilla. Add slightly cooled chocolate GRADUALLY so you do not fry the egg.
  • In a separate bowl, combine flour, cocoa, baking powder and salt and then gradually add to chocolate mixture.
  • Refrigerate dough.
  • Preheat oven.
  • Scoop dough onto cookie sheet and make a well in each cookie. Add a teaspoon of fluff and bake.
  • Meanwhile, heat your dipping chocolate according to instructions on the package. Add 1 heaping tablespoon peanut butter and microwave an additional 30 seconds. Stir until smooth.
  • Drizzle chocolate peanut butter topping on your cookies and allow to set.

Tips

  • Refrigerate the cookie dough for at least an hour before baking.
  • Use parchment or a silicone baking mat to prevent sticking.
  • Don’t overbake cookies. Watch bake time closely to keep cookies soft. 10 minutes is just perfect. Any longer and they may become hard and dry.
  • The cookies are ready when firm to the touch and slightly brown around the edges.
  • Let the cookies fully cool before topping them.

Frequently Asked Questions

Do you refrigerate marshmallow fluff?

Marshmallow creme (fluff) can stored at room temperature. However, refrigeration can extend the shelf life, especially after opening the jar.

Is marshmallow creme healthy?

It does contain sugar, and of course carbohydrates. However, it has no fat, no protein, cholesterol or fiber, so it has zero nutritional value. It has a touch less sugar per serving than most jellies or jams on the market.

  1. Hi Julie! I tried these tonight. They look beautiful. But they don’t seem to be setting up. They’ve been out of the oven for about 2 hours and when I try to take a spatula to scrape one off the cookie sheet, it is still very gooey and just mooshes all up. Is it 10 minutes at 325* for sure? The only thing I did different from the recipe was used milk chocolate chips instead of semi-sweet. Any thoughts! They’re delicious even as a mooshed clump (haha) but I wanted to make for a cookie exchange next week, so I need them to stay pretty. Thanks! 🙂

  2. HI Julie, thanks for the delectable recipe. I’m making them with my daughter as we speak. Question: the chocolate dough, before we put it into the refrigerator, was quite shiny and gooey, almost like chocolate icing. Is that how it’s supposed to be? Thanks.
