Peanut butter? Jelly? Peanut butter and jelly?

It's also great on Ritz crackers!
A couple days ago, needing something really sweet, I took and prepacked Rice Krispy Treat, slathed it with smooth Jif, and stuck a layer of chocolate chips in the peanut butter. I wish I wouldn't have liked it so much because I've been resisting doing it again every since.
