Notes

Butter - I recommend using real butter not margarine. If you use salted peanut butter you will run the risk of the fudge being a little extra salty.

Sprinkles - Sprinkles are optional. If you add them on lightly press them into the top of the peanut butter fudge to ensure they stay on.

Mix Ins - Chocolate chips, peanut butter chips, peanuts, etc.

Double the Recipe - Feel free to double the recipe if you want. Just use a 9x13 pan for the recipe to double.

Servings - This fudge is very rich. I recommend cutting into smaller pieces, as a little piece goes a long way.

Sifting Powder Sugar - If you sift the powder sugar it will help to give you an even creamier texture to the fudge. It is up to you if you choose to do it.
