Recipe Information
Ingredients
- 0.5 cup unsalted butter
- 1 cup peanut butter (creamy or chunky)
- 1 teaspoon vanilla extract
- 3.5 cups powdered sugar
- 1 pinch pinch of salt
Instructions
Grease an 8x8-inch baking dish or line it with parchment paper. Set aside.
In a microwave-safe bowl, add 1/2 cup of unsalted butter and 1 cup of peanut butter.
Microwave the mixture on high for 60 seconds. Remove from microwave, stir well, and then heat for another 30-60 seconds until the mixture is completely melted and smooth.
Add 1 teaspoon of vanilla extract and a pinch of salt to the melted mixture. Stir to combine.
Gradually sift in 3.5 cups of powdered sugar, stirring after each addition to ensure there are no lumps. Continue stirring until the mixture becomes thick and well integrated.
Transfer the fudge mixture to the prepared baking dish, spreading it out evenly with a spatula.
Refrigerate the dish for at least 2 hours or until the fudge is firm and set.
Cut the fudge into 16 equal squares and serve. Store any leftovers in an airtight container in the refrigerator for up to one week.
