This is what all fudge should be.
1 lb Smuckers All Natural PB (1 jar)
1/2 lb Butter (2 sticks) (Save the wrappers)
1 lb sugar free powdered sugar
1 tsp vanilla extract
10 oz bag of sugar free choc. chips.

Put some water in a boiler and then pour the choc. chips in a bowl and sit the bowl in the water that should be very hot, not quiet boiling but very hot. Ever once in a while stir the choc. Don't let a drop of water get in the choc. While that's melting:

Add the peanut butter to the sugar free powdered sugar and then add the melted butter, then the vanilla extract. Mix with a wooden spoon until it's mixed well then use your hands to knead the mixture.

Butter a 9" square pan, don't use a lot of butter, in fact you can even use the paper off the butter. Press the PB mixture in the pan. Pour the melted choc. over the PB. Put the pan somewhere to cool overnight. DO NOT put in the fridge. In the morning cut the fudge into squares and enjoy. This is by far the best fudge in the world. Don't use any other PB besides the one listed.
