Fluffernutter Cookies - Beyond the Butter® (2024)

The fluffernutter sandwich was a childhood favorite of mine, and I will confess to having quite a few sandwiches as an adult too. Haha! So it only seems fitting to share this fluffernutter cookie recipe inspired by the popular classic!

My classic peanut butter blossoms recipe also inspired this recipe and is a great year-round treat. I hope you enjoy them as much as I do! And for another yummy classic, give my chocolate-dipped peanut butter cookies a try!

What is a Fluffernutter Sandwich?

If you're unfamiliar with what a fluffernutter sandwich is, it's a layer of peanut butter with a layer of marshmallow fluff sandwiched between two slices of bread. It's a simple, sweet, and somewhat salty combo that's good!

Ingredients Needed

Below is the list of ingredients you'll need to make these peanut butter fluffernutter cookies, most of which you probably already have in your pantry! It's best to have the unsalted butter and egg at room temperature before baking.

• Peanut Butter. Creamy peanut butter is the best. The brand I always prefer to use is JIF Naturals.
• Unsalted Butter. Room-temperature butter is the best, which will help blend the other ingredients together. Trader Joe's unsalted butter is my usual go-to for baking.
• Marshmallow Fluff. This is also known as marshmallow creme. See the substitutions below for using mini marshmallows.

For quantities and instructions, please see the recipe card below.

Substitutions

Below are two substitutions that can be made to this fluffernutter cookie recipe.

• Butter. Omit the salt from the recipe if you substitute salted butter for unsalted butter.
• Marshmallow Fluff. Substitute 5-6 mini marshmallows per cookie for one tablespoon of marshmallow fluff.

Please note that I did not test this recipe using any additional flour, sugars, or egg substitutions.

Is an Ankarsrum Mixer Worth It?

Yes. 100% yes! I've owned my Ankarsrum Assistent Original® mixer for almost two years and straight up love it. I won't lie, owning one is an investment, and it took some time to get used to, but there is so much you can do with this mixer!

The Assistent Original comes with a 3.5-liter plastic mixing bowl with two different style whisk attachments, a 7-liter stainless steel bowl, a dough hook roller, a scraper spatula, a dust cover, and a removable power cord. And now, they also have a stainless steel 3.5-liter mixing bowl, which I used with this fluffernutter cookies recipe!

Compared to my KitchenAid® mixers, the Ankarsrum is much lighter in weight, has a 600-watt engine, the motor is on the bottom versus the top, so it doesn't shake at higher mixing speeds, has a 7-year warranty, and it comes in a ton of different colors—like this new bold and beautiful olive green!

Whether you're making these peanut butter fluffernutter cookies, my honey butter dinner rolls, or my dulce de leche ice cream, you'll be very impressed with this mixer!

How to Make the Recipe

Below is a quick overview of how to make these fluffernutter cookies. For the full printable recipe, visit the recipe card below. You'll have the choice to make these cookies using US customary or metric measurements.

Step 1. Whisk the dry ingredients in a small bowl. This includes all-purpose flour, baking soda, and salt. Set aside (Image 1).

Step 2. Beat the wet ingredients together. Use your Ankarsrum Assistent Original (or a hand mixer) to beat the peanut butter and unsalted butter together. Add the granulated sugar, light brown sugar, egg, and vanilla extract. Mix until well blended (Image 2).

Step 3. Add the dry ingredients to the wet. Mix until just combined (Image 3).

Step 4. Scoop the cookie dough onto the parchment paper-lined baking sheets. For the best results, use a 2-tablespoon-size cookie scoop (Image 4).

Step 5. Press the cookie dough balls into discs. You can use your fingers for this part. The cookie discs should be roughly 3 inches in diameter (Image 5).

Step 6. Scoop the marshmallow fluff onto each disc. For marshmallow fluff or marshmallow creme, use a 1-tablespoon size cookie scoop (Image 6).

Step 7. Carefully roll up the disc around the marshmallow fluff. I start by folding the edges together to form a half-moon shape; then, I bring the sides up to form the cookie dough ball (Image 7).

Note. This part can be messy, especially if the marshmallow fluff starts seeping through.

Step 8. Roll the cookie dough balls in granulated sugar. This optional step adds a sweet little crunch to the cookie when baked (Image 8).

Step 9. Bake the cookies. The recommended baking times are 350ºF for 10-12 minutes. Begin to check on them at the 10-minute mark. The cookies will spread a lot (Image 9).

Step 10. Reshape the cookies. If desired, you can take a large round cookie cutter and reshape the fluffernutter cookies right after you bring them out of the oven. If you don't have a cookie cutter wide enough to fit the cookies, you can use a spatula to push in the sides (Image 10).

Let the cookies cool on the baking sheet for 5-10 minutes before transferring them to a wire cooling rack to finish cooling completely.

Storage

It's best to store your peanut butter fluffernutter cookies in a well-sealed container at room temperature for up to 5 days. You can freeze the cookies in a well-sealed freezer container or freezer bag for up to 3 months.

To defrost them, let them sit at room temperature for 1-3 hours in their container before you enjoy them. You can also heat them in the oven for a couple of minutes. Just be sure to keep an eye on the marshmallow parts.

Do I need to refrigerate the peanut butter cookie dough?

No. Unlike my classic peanut butter blossoms recipe, you need not refrigerate the cookie dough before baking.

Can I use mini marshmallows in place of marshmallow fluff?

Yes. You can use 5-6 mini marshmallows instead of 1 tablespoon of marshmallow fluff.

What kind of peanut butter should I use for fluffernutter cookies?

I recommend using creamy peanut butter like JIF or JIF Naturals.
