How to Make Fluffernutter Bars

Step 1: Prepare Your Pan

Line an 8×8-inch baking pan with parchment paper or lightly grease it to ensure your Fluffernutter Bars will come out cleanly after setting.

Step 2: Melt Butter and Peanut Butter

In a medium saucepan over low heat, melt the butter and peanut butter together, stirring frequently until the mixture is creamy and fully combined.

Step 3: Stir in Marshmallow Fluff

Remove the pan from heat, then stir in the marshmallow fluff until it’s completely incorporated and you have a smooth, gooey mixture.

Step 4: Add Powdered Sugar and Flavorings

Gradually sift in the powdered sugar, mixing well to avoid lumps. Add vanilla extract and a pinch of salt, blending until uniform.

Step 5: Optional Add-Ins

If you’re adding crushed graham crackers, cereal, or chocolate chips, gently fold them in now for extra texture and flavor.

Step 6: Press Into Pan and Chill

Transfer the mixture to your prepared pan and press it down firmly with a spatula or your hands for an even layer. Refrigerate for at least an hour to set before slicing into bars.

Pro Tips for Making Fluffernutter Bars

• Use creamy peanut butter: It blends better for a smooth texture that’s easier to slice.
• Don’t skip the chill time: Let the bars set in the fridge to develop firmness and hold their shape.
• Measure powdered sugar carefully: Too much can make bars dry; too little will make them sticky.
• Line your pan with parchment: Makes removal effortless and clean edges guaranteed.
• Press firmly: Compact the mixture well for bars that hold together without crumbling.

FAQs

Can I use crunchy peanut butter instead of creamy?

Lining your pan with parchment paper or greasing it lightly will prevent sticking and make removal much easier.

Can I make these bars gluten-free?

Absolutely! Make sure to use gluten-free optional add-ins like rice cereal instead of graham crackers to keep the recipe gluten-free.

How long do Fluffernutter Bars keep?

Stored properly, these bars last up to 5 days at room temperature or in the fridge, and even longer if frozen.
