Potato Chip Chip Shortbread from Midwest Made. The recipe is available online here at NYT Cooking
For this recipe, you take a bunch of potato chip crumbs, mix half into a shortbread dough with chocolate chips then press the dough out onto a layer of potato chip crumbs, then top it with the rest of the crumbs.
There was supposed to be an egg wash on top before the chips went on but I forgot.
The idea took me back to those days as a kid when our after school snack tin was down to the crumbs. I actually loved getting a few salty potato chip or pretzel crumbs along with a fragment of a chocolate chip cookie or Oreo.
These are reportedly better the second day but they taste pretty fine right now.
