Krispy Scotcharoos

This is one of those recipes that my mom made when I was growing up. As an adult I looked for the recipe because she had gotten off a box of rice krispies. The recipe had changed over the years so you will notice that there is an alternative to the recipe - that is how my mother made it all those years while the recipe I have is the one rice krispies had during my search. It's been years since I found it so there is the possibility it has changed again. The only problem with this recipe is that it doesn't hold together as nicely as a rice krispie treat but they taste so good it doesn't matter.
