Does anyone know Jupiter Bars? They are a yummy chewy caramel peanut bar that I'm addicted to when I can find them. These are quite similar. I'm going to be honest and say this was much easier to do by hand using a microwave to melt and wooden spoon and bowl to mix but I'm going to give you the tmx instructions below. These are a yummy little treat and keep well in an airtight container for up to 2 weeks.
