I have updated the recipe and method only slightly, but overall, I share this pretty much as it was shown on the package. Thanks, Knox, for a family heritage recipe!
(Site note: I have been trying for several years to never post an entry without photos to attach. However, this is a special request that I haven't prepared myself today, so here it is for now. Will have to make some just to get some photos I guess!)
1 envelope unflavored gelatin
1/3 c sugar
1 c water
1 c peanut butter
1 c chocolate milk--see NOTE
1. Stir the gelatin, sugar, and water together in a 1 quart measuring cup or similar LARGE bowl, making sure it is well mixed. Allow to sit for about 5 minutes.
2. Microwave on high until the mixture begins to boil and is clear. Be watchful--it will boil up and spill over very quickly! Remove from the microwave and allow to cool slightly.
3. Beat in the peanut butter and then gradually add the chocolate milk. When completely blended, pour into popsicle molds, insert sticks, and freeze.
NOTE: Mix Nesquik or a similar powder into a cup of milk, as directed on the package. You can also use a package or two of hot cocoa mix prepared with water or, for extra richness, milk.
If you don't have popsicle molds, other small glasses (or bathroom size disposable cups) may be used. If you don't have molds, freeze the mixture until just slushy before inserting popsicle sticks so they remain as upright as possible.
