The Key to Fluffernutter Cookies: Ingredients and Smart Swaps

The Essentials: What You’ll Need

At the heart of Fluffernutter Cookies are two key players: creamy, rich peanut butter and ooey-gooey marshmallow fluff. These ingredients, along with a few baking staples like flour, sugar, eggs, and a dash of vanilla, create a cookie that’s both comfortingly familiar and excitingly unique.

But here’s the scoop – not all peanut butter is created equal. For the ultimate cookie experience, you’ll want to lean towards natural, unsweetened peanut butter. Why? It brings a depth of flavor that those added sugars and oils just can’t match. And as for the marshmallow fluff, the lighter and airier, the better. It’s what gives these cookies their signature fluffy texture.

Let’s Get Mixing!

Now that we’ve got our ingredients lined up, it’s time to get down to business. First up, creaming together the peanut butter and sugars until they’re just right. Then, in go the eggs and vanilla, making everything nice and smooth. The dry ingredients follow, gently folded into the mix, paving the way for the star of the show – marshmallow fluff.

Here’s a little secret: dollop the fluff onto your cookie dough before gently swirling it in. You’re not aiming for a complete mix. Those marshmallowy streaks? They’re gold, making each bite a heavenly blend of peanut butter goodness and marshmallow lightness.

How To Make Fluffernutter Cookies: The Step-by-Step Guide


  • 1 cup (250g) natural, unsweetened peanut butter
  • 1 cup (200g) granulated sugar
  • 1/2 cup (100g) light brown sugar, packed
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 and 1/2 cups (190g) all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup (120ml) marshmallow fluff


Preheat and Prepare:

  1. Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats. This prevents the cookies from sticking and ensures easy cleanup.

Mix the Wet Ingredients:

  1. Cream the Peanut Butter and Sugars: In a large mixing bowl, combine the peanut butter, granulated sugar, and brown sugar. Beat with an electric mixer on medium speed until the mixture is light and fluffy, about 2-3 minutes.
  2. Add Eggs and Vanilla: Beat in the eggs, one at a time, ensuring each is well incorporated before adding the next. Stir in the vanilla extract.

Combine the Dry Ingredients:

  1. Whisk the Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt. This ensures these ingredients are evenly distributed throughout the dough.

Combine Wet and Dry Ingredients:

  1. Mix Dry into Wet: Gradually add the dry ingredients to the wet, mixing on low speed just until the dough comes together. Be careful not to overmix to keep your cookies tender.

Add Marshmallow Fluff into Your Fluffernutter Cookies

  1. Incorporate Marshmallow Fluff: Once your dough is ready, it’s time to introduce the marshmallow fluff. But not so fast! This isn’t a job for the heavy-handed. Gently swirl dollops of fluff into the dough, aiming for a marbled effect. You want pockets of marshmallow goodness in every bite, not a uniform blend. Think of it as creating little clouds of joy throughout the dough, ensuring each cookie has its own unique fluff-to-dough ratio.

Shape and Bake:

  1. Shape the Cookies: Scoop the dough by heaping tablespoons onto the prepared baking sheets, spacing them about 2 inches apart. The cookies will spread as they bake.
  2. Bake: Place in the preheated oven and bake for 8-10 minutes, or until the edges are just beginning to brown. The centers might seem soft, but they will firm up as the cookies cool.


  1. Cool: Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. This rest period helps the cookies set without becoming hard.


  1. Serve: Once cooled, serve your Fluffernutter Cookies and watch them disappear! They’re best enjoyed fresh but can be stored in an airtight container for up to a week.

Creative Variations and Healthier Alternatives

Baking is an art, and every artist loves to experiment. Fluffernutter Cookies, with their delightful blend of peanut butter and marshmallow fluff, provide a perfect canvas for culinary creativity.

Fun Variations to Spice Up Your Fluffernutter Cookies Batch

Why stick to the basics when you can make your Fluffernutter Cookies stand out? Here are some ideas to get those creative juices flowing:

  • Chocolate Chip Magic: Who can resist the allure of chocolate chips? Sprinkle a generous handful into your dough for a classic twist.
  • Nutty By Nature: For an extra crunch, fold in chopped peanuts or almonds. It’s not just about the texture; it’s about enhancing the nutty flavor.
  • Sea Salt Sprinkle: Just before baking, sprinkle a light dusting of sea salt on top of each cookie. This little trick balances the sweetness and brings out the flavors.
  • Marshmallow Center: Instead of mixing in the fluff, form your dough around a spoonful of marshmallow creme, creating a surprise center that oozes with each bite.

Making Fluffernutter Cookies Healthier

Indulging in your favorite treats doesn’t have to mean abandoning your health goals. Here are some modifications to keep your cookies on the lighter side:

  • Whole Wheat Flour: Swap out all-purpose flour for whole wheat for added fiber. It gives the cookies a nuttier, heartier texture, aligning well with the peanut butter.
  • Reduced Sugar: Consider reducing the sugar by a third or substituting part of it with natural sweeteners like honey or maple syrup. Remember, the marshmallow fluff adds sweetness, so you can afford to cut back elsewhere.
  • Natural Peanut Butter: If you haven’t already, using natural, unsweetened peanut butter reduces sugar and eliminates hydrogenated fats.
  • Portion Control: Sometimes, it’s not about changing the recipe but how you enjoy it. Bake smaller cookies or savor half a cookie as a treat, enjoying every bite mindfully.

Fluffernutter Cookies Nutritional Considerations

While Fluffernutter Cookies are undoubtedly a treat, being aware of their nutritional content helps you fit them into a balanced diet. Remember, moderation is key. Enjoying a cookie (or half) as part of a diet rich in fruits, vegetables, lean proteins, and whole grains keeps your sweet tooth satisfied without overindulging.

Frequently Asked Questions About Fluffernutter Cookies

Fluffernutter Cookies, as simple and delightful as they are, often bring up a few questions, especially when bakers are eager to get every detail right. Let’s clear up some of those queries:

Are Fluffernutters Healthy?

While Fluffernutter Cookies are a treat, and treats are typically indulged in moderation, there are ways to tweak the recipe for a healthier version. Incorporating whole wheat flour, reducing sugar, and using natural peanut butter are steps in the right direction. Remember, balance is key in a healthy diet, so enjoying these cookies as an occasional treat within a balanced diet is perfectly fine.

What is Fluffernutter Made Of?

The classic fluffernutter combo involves peanut butter and marshmallow fluff. When it comes to the cookies bearing the same name, these two ingredients, along with staples like flour, sugar, and eggs, create the beloved treat. The interplay between the nutty peanut butter and the sweet, airy marshmallow fluff is what gives these cookies their signature appeal.

What Happens to Marshmallow Fluff in the Oven?

Marshmallow fluff undergoes a delightful transformation in the oven. It melts slightly, integrating into the dough around it, which results in pockets of gooey sweetness within the cookies. However, it doesn’t disappear; it becomes part of the cookie’s texture, contributing to the unique taste experience of Fluffernutter Cookies.

Can I Use Marshmallows Instead of Marshmallow Creme?

Yes, you can! While marshmallow creme is smoother and easier to mix or swirl into the dough, marshmallows are a viable alternative. They melt differently, potentially creating more distinct pockets of marshmallow within the cookies. If you’re using marshmallows, consider cutting them into smaller pieces for more even distribution.

Can Diabetics Eat Marshmallow Fluff?

For individuals managing diabetes, consuming foods high in sugars, like marshmallow fluff, requires careful consideration. It’s essential to pay attention to portion sizes and how the treat fits into your overall meal plan. Consulting with a healthcare provider for personalized advice is always a good approach.

Is Marshmallow Fluff Healthier Than Jelly?

When comparing marshmallow fluff to jelly, it’s crucial to look at their sugar content and nutritional information. Generally, both are high in sugars and should be consumed in moderation. The choice between them should depend on personal dietary needs and preferences. Neither is significantly “healthier” than the other, as both are sweet treats meant for occasional enjoyment.
