Prepare an 8x8-inch baking dish by lining it with parchment paper or lightly greasing it with a nonstick spray.
In a microwave-safe bowl, combine the unsalted butter and smooth peanut butter.
Microwave the mixture on high for 1 minute. Remove and stir until fully combined and smooth.
Microwave for an additional 30 seconds to ensure the butter and peanut butter are fully melted and integrated.
Stir in the vanilla extract until evenly distributed.
Gradually add the powdered sugar, stirring well after each addition, until the mixture becomes smooth and thick.
Pour the fudge mixture into the prepared baking dish and spread it evenly using a spatula or the back of a spoon.
Refrigerate the fudge for at least 2 hours, or until firm.
Once set, remove the fudge from the baking dish by lifting the parchment paper or gently loosening the edges.
Cut the fudge into 16 equal squares and serve. Store any leftovers in an airtight container in the refrigerator for up to a week.
