Fluffernutter Cookies - Soft, chewy, and gooey delicious! #cookies #dessert #peanutbutterandchocolate

These cookies are like the perfect marriage between soft baked chocolate chip cookies and a fluffernutter sandwich! Peanut butter, chocolate, and marshmallow come together in a soft, gooey cookie you won’t be able to resist! Seriously. Good luck not eating the whole batch at once. These are dangerous.

These are super simple to make, but there is one thing to keep in mind. After you mix up the dough and scoop it onto a cookie sheet, press a few marshmallows into each cookie. Be careful to not get marshmallows on the edges because they will melt and caramelize on the cookie sheet. We don’t want that. We want super soft cookies here!

Now what are you waiting for? Go make some cookies :)

Soft and Chewy Fluffernutter Cookies

These Soft and Chewy Fluffernutter Cookies are utterly irresistible! Ultra soft peanut butter cookies loaded with marshmallows and chocolate chips. Divine!


  • 1 cup unsalted butter (softened)
  • 1/2 cup creamy peanut butter
  • 2 tablespoons coconut oil (or canola oil)
  • 1 1/2 cup brown sugar (packed)
  • 2 eggs
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 2 1/4 cups all purpose flour
  • 2 cups semi sweet chocolate chips
  • 1 1/2 cup mini marshmallows


Step 1
Preheat oven to 350
In a large mixing bowl cream the butter, oil, and sugar until light and creamy. Add eggs, salt, and vanilla and mix well. Mix in baking soda and baking powder, and gradually mix in flour until combined. Stir in chips and marshmallows.
Step 2
Drop spoonfuls of dough on a silpat or parchment paper lined cookie sheet about 2" apart. (If any marshmallows are on the very edges of the cookies, move them into the middle or they will caramelize and get a bit crunchy.) Bake for 7 minutes and let rest on cookie sheet 5 minutes before transferring to wire cooling rack.
Store tightly covered and room temperature.

    Those look fantastic! I love fluffernutters. :) Pinned!

  2. Germaine says:

    Just wondering if hard margarine can be used instead of unsalted butter due to a 3 pound box of margarine is the same price as 1pound of butter. Thanks.

    • Hi Germaine,
      Honestly, I would not recommend using margarine. You will not get the same flavor or texture that butter will give. I know butter is more costly (trust me, I buy tons of it!) but it really works better for this recipe. Hope you enjoy the cookies!
