I came across this recipe in a stack that I was sorting and realized that this recipe from weedsnstitches, posted June 2, 2015, on the King Arthur Baking Circle, is not posted here at Nebraska Kitchen. I am adding it. She says, "This is the recipe my mom has been using since the 70s. It is really, really good. They are chewy and have a butterscotch flavor. She usually doubles the recipe so it is in a 13x9 inch pan because they don't last long."
