This is a very rich, very sweet pudding and for that reason I did not garnish it with the suggested garnishings. Half and half could easily be substituted with ordinary milk. You could also make do with about 1/2 cup of peanut butter if necessary. Substituting some of the sugar with maple syrup would also be yummy.
I served this after a family dinner last night, and opposite to what I expected the grown ups really liked it, and the kids turned their noses up at it. I doubled the recipe, and used only 2% milk and 1 cup of peanut butter total. The result was a very sweet and heavy pudding. I actually liked it better warm where it would be wonderful spooned over some fresh pound cake!
