Fluffernutter Bars Ingredients
For the Cookie Base
• Butter – Softened for moisture and richness; use unsalted for better control over saltiness.
• Peanut Butter – Smooth or creamy; adds that nutty flavor, but steer clear of natural peanut butter to avoid oil separation.
• Brown Sugar – Packed; enhances sweetness and chewiness; you can substitute it with white sugar if needed.
• Egg – Provides structure and binds all the ingredients; no substitutions recommended.
• Vanilla Extract – Adds depth to the flavor; opt for pure vanilla for the best result.
• All-Purpose Flour – Forms the base of the cookie dough; gluten-free flour is a good alternative for gluten-sensitive friends.
For the Additions
• Peanut Butter Cups – Chopped, regular size; offers delightful chunks of peanut butter sweetness; use a gluten-free variety if necessary.
• Chocolate Chips – Semi-sweet; enriches the bars with extra chocolatey goodness; feel free to substitute dark chocolate chips for a richer flavor.
• Marshmallow Creme/Fluff – Adds that creamy layer; in a pinch, mini marshmallows work—just adjust baking times.
Now that you have all your ingredients ready, let’s get baking these decadent Fluffernutter Bars that are sure to be a hit!
Step‑by‑Step Instructions for Fluffernutter Bars
Step 1: Preheat and Prepare Your Pan
Start by preheating your oven to 350°F (175°C). While it warms up, take an 8×11 inch baking pan and line it with parchment paper, allowing some overhang on the sides for easier removal later. This setup ensures your Fluffernutter Bars will come out smoothly once baked.
Step 2: Make the Cookie Dough
In a large mixing bowl, beat together 1 cup of softened butter and 1 cup of packed brown sugar until the mixture is light and fluffy, which should take about 3 minutes. Next, add in 1 egg, 1 cup of peanut butter, and 1 teaspoon of vanilla extract, mixing until fully combined to create a deliciously rich cookie base.
Step 3: Add the Dry Ingredients
Gradually incorporate 2 cups of all-purpose flour into the cookie dough mixture, stirring until just combined. Gently fold in 1 cup of semi-sweet chocolate chips, ensuring they are evenly distributed throughout the dough for that delightful chocolatey flavor in your Fluffernutter Bars.
Step 4: Press Dough into Pan
Take about two-thirds of your cookie dough and press it evenly into the bottom of the prepared baking pan. Use your hands or a spatula to ensure an even layer that forms the foundation of your Fluffernutter Bars, creating a sturdy base for the upcoming layers.
Step 5: Layer with Peanut Butter Cups
Evenly sprinkle 1 cup of chopped peanut butter cups over the cookie layer you just pressed down. Make sure to distribute them well so every bite of your Fluffernutter Bars is filled with that delightful peanut butter crunch, enhancing the texture of your bars.
Step 6: Add Marshmallow Fluff
Spread a generous layer of marshmallow fluff over the peanut butter cups, ensuring it’s evenly coated. This creamy layer adds richness and a sweet texture that will make your Fluffernutter Bars incredibly gooey and irresistible once they’re baked.
Step 7: Top with Remaining Dough
Take the remaining cookie dough and gently spoon it over the marshmallow fluff layer. Use your fingers to press it down lightly, ensuring even coverage without disturbing the layers below. This seals in all the delicious flavors and gives your Fluffernutter Bars a beautiful finish.
Step 8: Bake to Perfection
Bake in the preheated oven for about 25 minutes or until the top is golden brown and slightly firm to the touch. The aroma of baking should fill your kitchen as your Fluffernutter Bars transform into a delicious dessert that’s hard to resist.
Step 9: Cool and Slice
Once baked, take the pan out of the oven and allow it to cool for 1 hour. Then, using the parchment overhang, lift the bars out of the pan. Let them cool completely on a wire rack before slicing into squares, ensuring each piece has that perfect gooey texture.

Chill Before Slicing: For cleaner cuts, refrigerate the cooled bars for an hour. This helps achieve that perfect slice, making your presentation beautiful.

Fluffernutter Bars Recipe FAQs
How do I know if my ingredients are ripe and ready to use?
For the best flavor and texture in your Fluffernutter Bars, ensure your butter is softened but not melted. Look for a creamy consistency that’s easily spreadable, which usually takes about 30 minutes at room temperature. Your peanut butter should be smooth and creamy, avoiding natural types that can separate. Check your chocolate chips for taste freshness; they should be clean and not have an off smell.
How should I store leftover Fluffernutter Bars?
You can store leftover Fluffernutter Bars in an airtight container at room temperature for up to 3 days. To maintain their chewy texture, refrigeration is an option; they’ll last up to one week in the fridge, though this might slightly alter their gooeyness. Just remember to let them sit at room temperature for a few minutes before enjoying!
Can I freeze Fluffernutter Bars?
Absolutely! To freeze your Fluffernutter Bars, first cool them completely once baked. Wrap each bar tightly in plastic wrap and then place them in a freezer-safe zip bag. They can be stored in the freezer for up to 2 months. When you’re ready to indulge, simply thaw them overnight in the refrigerator and warm slightly in the microwave for that irresistible gooey texture.
What should I do if my bars don’t seem to be baking properly?
If you find your Fluffernutter Bars are undercooked, it might be that your oven temperature is off, or the pan size you used is larger. I recommend checking them a few minutes earlier or ensuring you stick to the cooking time and pan size specified in the recipe. If they’re overcooked and too dry, next time try reducing the baking time by a few minutes or covering with foil if the edges get too brown.
Are Fluffernutter Bars safe for people with allergies?
These Fluffernutter Bars contain common allergens such as peanuts and eggs, so they’re not suitable for individuals with peanut allergies. If you’re looking to make a nut-free version, you could substitute almond butter or sunflower seed butter, but double-check all your other ingredients, including chocolate chips and marshmallow fluff, to ensure they’re allergy-friendly.
Can I make substitutions in this recipe?
Yes! If you’re allergic to allergens or simply want to change things up, you can use crunchy peanut butter instead of smooth for added texture. Additionally, butterscotch chips can swap with chocolate chips to create a unique flavor, or mix in crushed graham crackers for a s’mores-inspired twist. Enjoy experimenting!
