Why This 2-Ingredient Fudge Works So Well
Traditional fudge relies on sugar stages, precise temperatures, and constant stirring. This recipe skips all of that by using two perfectly balanced ingredients:
-
Peanut butter provides fat, structure, and flavor
-
Prepared frosting supplies sweetness, creaminess, and stability
When melted together, they form a smooth, glossy mixture that firms up beautifully in the refrigerator—no guesswork required.
