2 c. vanilla sugar (or add a tablespoon of pure vanilla extract if you don't have V. sugar)
1/2 c. Hershey's Cocoa
1/3 c. water
Combine in a saucepan and bring that mixture to a boil. Boil at least 2 minutes. That takes the grittiness out of the sugar. Do Not skip this step.
Remove from heat and stir in about 2/3 c. of PB. Here I'm just guessing. I take a regular tablespoon and plop 3 big spoonsful in the hot mix.
Add the vanilla if it's not in the sugar.
While the Choc/PB mixture is heating up, Put 1 qt of half and half and 1 pint of heavy whipping cream in the freezer can.
Whip 4 eggs and and add them to the cream. Mix well.
Add the hot mixture and mix it very well.
Plug in the freezer or start cranking by hand if that's what you use. 20-30 minutes later, enjoy.
