Prepare 8×8 inch square baking dish by lining it with parchment paper and set aside.I didn’t use parchment paper and just used my butter wrappers to grease the pan.
Over medium heat, in a saucepan, combine the peanut butter, vanilla, butter, and salt.Cook until it’s smooth, stirring frequently.
Remove from heat and with a spatula, stir in the powdered sugar.
Spread the fudge evenly in the baking sheet and top with desired toppings.
