I had the most amazing yet simple bar cookie once and would like to try my hand at making them but can't find any information online. It is a bar cookie with a sandy texture on top that gets chewy on the bottom but not cake-like at all, it is very dense. I vaguely recall some finely minced nuts towards the bottom and it tastes like brown sugar. Has anyone heard of these? Any info I find on sand bars is an entirely different cookie. Any help would be appreciated.
