What is a FlufferNutter?

A fluffernutter sandwich is made of peanut butter and marshmallow fluff on white bread. It is a simple and classic sandwich.

How to make Fluffernutter Cookies

These step by step instructions for fluffernutter cookies are very easy to follow. They mimic most cookie recipes from scratch.

  • Prep oven and baking sheets. Preheat oven to 350 degrees F. Line two baking sheets with parchment paper or spray with nonstick cooking spray.
  • Butter Cream and Sugars. Using a hand mixer, cream together the butter, sugar, and light brown sugar until smooth and creamy. This should take around 2-3 minutes.
  • Add the egg and vanilla. Mix the egg and vanilla extract with the hand mixer until just combined.
  • Add Dry Ingredients. Mix the cornstarch, flour, and baking soda together with a spoon or spatula. Do not over mix.
  • Mix marshmallows and chips. Add marshmallows and peanut butter chips. Make sure they are evenly incorporated. You may have to use your hands for this.
  • Form balls of dough. Scoop out the cookie dough and roll it into balls. Each tablespoon should be about 2 tablespoons.
  • Bake. Bake for about 10-12 minutes. The edges will start to brown, but the center will still feel soft. They will finish cooking when they cool down.
  • Cool and Serve. Let your cookies cool on the baking sheet for about 5 minutes, then transfer to a cooling rack to cook completely. So enjoy it!

How to Store Fluffernutter Cookies

Store your fluffernutter cookies in an airtight container for up to 5 days at room temperature. You can also freeze them for up to 2 months! After storing them, I personally like to microwave them for 5-10 seconds to let the marshmallow melt a bit.

tips and tricks

Here are some helpful tips for this recipe!

  • You can use a measuring spoon if you don’t have one. cookie scoop. I like to dip the spoon before adding the marshmallow creme for easy removal.
  • Make sure your butter is at room temperature.
  • Instead of marshmallow cream, you can use mini marshmallows. I have tried both versions. The mini marshmallows were good, but I definitely liked the consistency better using the marshmallow fluff.
  • If your dough gets too hot, place it in the fridge before dividing into balls.
  • For a fun twist, substitute the peanut butter chips for the chocolate chips.
  • Not a fan of marshmallows? Feel free to skip the marshmallows altogether and enjoy them as thin, chewy, and soft peanut butter cookies.
