Either the regular old fashioned Reeses Cups or the new Big cups. I’m not a great fan of the mini-cups. In order to help us portion control either two per pack or singles of the smaller size or one per pack of the big cups. Sorry to be so picky, but we need these things to last and if we open a whole package and are presented with 3 or 4 (in a king size) we’ll have to eat them…we don’t have any way to store them once opened.
