My daughter Hannah based this recipe on one she found in a book entitled Teens Cook Dessert. She had a friend sleep over and they made it together. Even better, they shared it with all the girls in their youth group that night. Everyone loved it. We can't wait to make it again. Although the recipe instructs to let them sit overnight, we found they didn't reach the soft, creamy, melt in your mouth butter mint texture until they had sat for two and half or three days - perhaps because we live in humid Florida. They are just as delicious if you eat them sooner, but have more of a salt-water taffy, chewy, sticky texture. WARNING - Read through the recipe first. Purpleturtle must not have realized what work she was in for.
