Don't be sorry - I didn't mean to imply you shouldn't ask the question. Just that I know there have been discussions about this aspect of cookies previously - perhaps you could do a search on Google of r.f.c posts.
I don't have a plain or choc chip recipe like this that I make often, so can't help there. If you like peanuts, though, I do make this recipe a lot, and they make thin, chewy-crispy, very moreish biccies (cookies) -
This recipe is actually from a kid's cookbook that I got in high school - I've had it for about 26-27 years now. Kitchen Wizard - the recipes are all in themed chapters, and this one's from A Huckleberry Finn Raft great book for encouraging kids to cook. I've posted this here before, I think. They are really good, and I have to give them away or I'd eat them all.
Playin' Hookey Cookies
from Kitchen Wizard, Deborah Jarvis
125g soft butter 125g crunchy peanut butter 125g granulated sugar 125g brown sugar 1 egg 1-2 tsp vanilla 150g self raising flour 50g crushed or chopped peanuts (optional - but I always add)
Cream butter and peanut butter till light and fluffy Add sugars gradually. Beat in egg and vanilla Mix in sifted flour and crushed nuts if using.
Roll dough into small balls about the size of walnuts. Place on baking tray about 5cm apart. Flatten with floured fork. Bake just above the centre of 180C (350F) oven for 10 - 12 minutes. Let cookies sit on tray for a couple of minutes (they're very soft when straight out of oven) then remove with palette knife and cool on rack.
