Fluffernutter Bars Ingredients
For the Cookie Base

- Brown Sugar – Packed brown sugar helps create that desired gooey texture and adds sweetness.
- Egg – Acts as a binding agent, ensuring your Fluffernutter Bars hold their shape.
- Vanilla Extract – A quality vanilla extract enhances the flavor beautifully.
- All-Purpose Flour – Provides structure; substitute with gluten-free flour if needed.
For the Toppings
- Peanut Butter Cups – Regular-sized cups are ideal, offering chocolatey and nutty chunks in every bite.

- Marshmallow Fluff – This creates the signature ooey-gooey texture of your Fluffernutter Bars; can be replaced with homemade marshmallow topping.
Step‑by‑Step Instructions for Fluffernutter Bars
Step 1: Preheat Oven
Start by preheating your oven to 350°F (175°C). Prepare an 8×11 inch baking pan by lining it with parchment paper, leaving some overhang for easy removal later. This step ensures that your Fluffernutter Bars bake evenly and can be easily lifted out of the pan once cooled.
Step 2: Make Cookie Dough
In a large mixing bowl, combine softened unsalted butter and packed brown sugar. Beat them together until the mixture is light and fluffy, about 2-3 minutes. Then add the egg, regular peanut butter, and vanilla extract, mixing until well-combined. Gradually fold in all-purpose flour and chocolate chips until just incorporated, creating a thick, gooey cookie dough.
Step 3: Layer Dough in Pan
Take about 2/3 of the cookie dough and evenly press it into the prepared baking pan, forming a solid crust. The dough should reach the corners and create a smooth bottom layer. This base will support the delightful toppings, so ensure it’s compact and even for best results with your Fluffernutter Bars.
Step 4: Add Peanut Butter Cups
Layer the chopped peanut butter cups evenly over the pressed cookie dough in the pan. Make sure to distribute them well so that every bite of your Fluffernutter Bars will include a delightful mix of chocolate and peanut butter flavors. Press the cups gently into the dough to secure them for the next layer.
Step 5: Spread Marshmallow Fluff
Carefully spoon marshmallow fluff over the peanut butter cups, spreading it evenly with a spatula. This layer of fluff is key to achieving that signature ooey-gooey texture in your Fluffernutter Bars. Ensure that the fluff covers the entire surface to create a luscious, sweet topping.
Step 6: Add Remaining Cookie Dough
Take the reserved cookie dough and crumble it over the marshmallow fluff, covering it entirely. Use your fingers to gently press the dough into place, ensuring it adheres to the fluff and creates a cohesive top layer. This step is essential for holding your Fluffernutter Bars together during baking.
Step 7: Bake the Bars
Place the baking pan in the preheated oven, and bake the Fluffernutter Bars for about 25 minutes. Keep an eye on them; the edges should turn golden brown while the center remains soft but set. A toothpick inserted into the center may come out slightly sticky, which is perfect for this dessert.
Step 8: Cooling
After baking, remove the pan from the oven and let the Fluffernutter Bars cool in the pan for one hour. This cooling period allows them to firm up for easy slicing. Once cooled, gently lift the bars out using the parchment overhang and transfer them to a cooling rack to cool completely before enjoying.

Expert Tips for Fluffernutter Bars
Proper Butter Temperature: Ensure your butter is softened, not melted. This helps achieve a light and fluffy cookie base without compromising texture.
Avoid Overmixing: When incorporating flour into the cookie dough, mix until just combined. Overmixing can lead to dense bars instead of the desired chewy texture.

Cooling Time Matters: Let the Fluffernutter Bars cool fully before slicing. This helps them hold their shape and makes for cleaner cuts.
Storage Best Practices: Store leftover bars in an airtight container at room temperature for 2-3 days. This ensures they remain fresh and delicious for every bite!
Fluffernutter Bars Recipe FAQs
How do I know if my ingredients are ripe or suitable for this recipe?

If your bars turn out too gooey, it might be due to underbaking. Make sure to set a timer for 25 minutes and check the edges; they should be golden brown while the center remains slightly soft.
