I'm looking for a recipe that I remember as a kid, say 1950s or 60s. They were a kind of layered date bar, or date nut bar. I can find tons of recipes for the bars where the dates (and nuts) are baked in a soft-chewy bar (where the dates are mixed into the dough) and then you cut them and roll them in confectioner's sugar while warm. But what i'm looking for was made in layers - I believe with a sort of crumbly top layer, dates in the middle and some kind of ? crust ? on the bottom. They were very popular then, and i remember them being called date bars or date nut bars. Could possibly have oatmeal in the topping part. They were very popular then.
