How to Make Fluffernutter bars
Step 1: Prepare Your Pan
Line an 8×8-inch square pan with parchment paper or lightly grease it to ensure the bars release easily after setting.
Step 2: Combine Butter and Peanut Butter
In a medium saucepan over low heat, melt the butter and peanut butter together, stirring continuously until the mixture is smooth and well blended.
Step 3: Mix in Marshmallow Fluff and Vanilla
Remove the peanut butter mixture from heat, then stir in the marshmallow fluff and vanilla extract until perfectly combined and silky smooth.
Step 4: Add Dry Ingredients
Fold in the powdered sugar and graham cracker crumbs gradually to the wet mixture. This will give the bars a perfect balance of sweetness and structure.
Step 5: Press and Chill
Transfer the mixture into your prepared pan, pressing it firmly and evenly. Refrigerate for at least two hours until the bars are set and easy to cut.
