My sister and nephew and I made these last weekend. They are a traditional Christmas treat in my family. I would give the recipe here but I don't measure the ingredients when making these.
You will need:
Peanut Butter (I used creamy JIF but you could use a crunchy type, too)
Semi-sweet chocolate, melted
First mix together peanut butter and powdered sugar in a large bowl. The best way to do this is to mix with clean hands or with plastic gloves on. I've tried to use a fork or a wooden spoon but it doesn't really mix it that well. Also, you will need to pinch a piece off periodically to see if it is the right consistency. You should be able to roll it into a ball pretty easily. If it is too sticky and won't keep a ball shape, add more sugar. If it is too dry and crumbles rather than forming a ball, add more peanut butter. After all your balls are formed (make them about the size of a quarter - bite size) refrigerate for about an hour. Melt semi-sweet chocolate in a double-boiler or microwave (15 second bursts on defrost, then stir - stop heating while there are still a few lumps so as to avoid burning the chocolate). We coated our peanut butter balls using two spoons but you could use tongs for dipping or pour the chocolate over. Once covered in chocolate, place balls on wax paper and put in fridge. These actually have no dairy in them, except the chocolate, so could be left at room temperature.
