* Combine: In a saucepan over medium heat, mix the warmed frosting and the peanut butter. Stir constantly until the mixture is completely smooth and well combined.
* Spread: Once the mixture is smooth, pour it evenly into a greased 8×8 inch baking pan.
* Set: Let the fudge cool for about an hour or until it is completely firm. You can speed up this process by placing it in the refrigerator.
* Serve: Cut into small squares and enjoy!
Variations and Tips
* Add Texture: For a little crunch, consider adding crushed peanuts or pretzel pieces to the fudge mixture before it sets.
* Flavor Swap: Use chocolate frosting instead of vanilla for a chocolate-peanut butter twist.
* Sweet & Salty: Sprinkle a little sea salt on top before it sets to create a delicious flavor contrast.
