If you’re not concerned about the salt content of your recipe, feel free to use salted butter and reduce or eliminate any salt that is called for in the recipe.

Why won’t my Peanut Butter Fudge harden?

If your Peanut Butter Fudge won’t harden, it’s likely that it didn’t cook long enough or get hot enough. You can try adding it back to the pan, adding just enough milk to stir it and bringing it to a boil again.

Why is my Peanut Butter Fudge oily on top?

If the butter gets too hot, it can separate and leave an oily layer on top. Fudge is basically an emulsion of butter, milk, and sugar.
