Thanks Just Cooking. Hadn't been to that site before (I don't think).
i once found some recipes for just 2 cookies. I didn't like the fact you only used one part of the egg, necessitating finding a rcipe for the other half. Then the cookies baked up so huge! LOL they almost overflowed the sheet in the toaster oven! That particular recipe was for Choc Chip and all the chips were in the middle of the cookie - making an almost solid centre of choc and the cookie around the outside. Very weird.
At the moment my favourite cookie is on the bag of Salted Caramel Chips. I make those up, roll them into a couple of logs, wrap and freeze. Slice off whatever I crave - more often than not, the oven doesn't even get turned on.
