About the easiest candy I make is to pour caramel into rice krispies in a pan lined with aluminum foil sprayed with olive oil as a release agent.
When cool, cut into strips ~1/2 inch wide. Press a pecan half into the side with the least rice, cut to length and cover with chocolate. All the cooled components sit on wax paper.
I have Nestle milk chocolate and premium white chips from our last warehouse club trip. Just looked for O Henry bar recipe—it must have been on old computer that crashed—it has chocolate, corn flakes, peanut butter, corn syrup and maybe some other stuff—tasty—will remit to you if you don’t already have it. (I know I have the hard copy in one of the binders—locating the correct binder is the issue.)
