I have been making peanut brittle since I was tiny. My other grandmother was the cook and she made it at least monthly if not weekly. Were you thinking about pralines? They are candy/cookieish but probably more candy. Or moon pies? - they are cookies. This grandmother taught us how to make taffy - her homemade taffy was delicious.
There is a Persian confection made with pistachios that is like peanut brittle and it is delicious as well. A student brought me back some after going to visit his family in the Middle East.
