Step-by-Step Instructions
Step 1: Prepare your pan
Line an 8×8 or 9×9 inch square baking dish with parchment paper, leaving overhang on the sides to lift the fudge easily once set.
Step 2: Melt butter and peanut butter
In a microwave-safe bowl, combine 1 cup of butter and 1 cup of peanut butter. Microwave in 30-second intervals, stirring in between, until fully melted and smooth. You can also do this over medium heat in a saucepan if preferred.
Step 3: Add vanilla and powdered sugar
Remove from heat and stir in 1 teaspoon of vanilla extract. Gradually add 3¾ cups of powdered sugar, stirring until fully combined and no lumps remain. The mixture will become thick.
Step 4: Press into pan and chill
Transfer the fudge mixture into your prepared pan. Use an offset spatula to spread it evenly and smooth the top. Chill in the refrigerator for at least 2 hours or until fully set.
Step 5: Cut and serve
Lift the fudge out using the parchment paper, then slice into 1-inch squares using a sharp knife. For best results, wipe the knife clean between cuts.
