Recipe Information
Ingredients
- 1 cup Peanut butter
- 0.5 cup Unsalted butter
- 2 cups Powdered sugar
- 1 teaspoon Vanilla extract
- 0.25 teaspoon Salt (optional)
Instructions
Line an 8x8-inch square baking dish with parchment paper or lightly grease it. Set aside.
In a microwave-safe bowl, combine the peanut butter and unsalted butter.
Microwave on high for 1 minute. Stir the mixture well to ensure the butter and peanut butter are fully combined.
Microwave the mixture again in 30-second intervals, stirring after each interval, until the mixture is smooth and melted (approximately 2 additional minutes).
Stir in the powdered sugar, vanilla extract, and salt (if using) until fully combined. The mixture will be thick, but ensure there are no lumps of powdered sugar.
Transfer the fudge mixture into the prepared baking dish. Use a spatula to press it evenly into the dish.
Refrigerate the fudge for at least 2 hours or until it is firm and set.
Once set, remove the fudge from the dish by lifting it out with the parchment paper. Cut into 16 small squares.
Serve and enjoy! Store leftovers in an airtight container in the refrigerator for up to one week.
