I'm looking for a recipe for crumb buns, very light airy buns rather than a cake even one with yeast. Appreciate any examples.

Is this a NY, NJ and/or Jewish bakery delicacy? If yes, there are tons of recipes out there.
If not, could you give more description?

I'm not sure what these are, but I'm intrigued! Does something like this seem right? https://www.washingtonpost.com/archive/lifestyle/food/2002/11/06/crumb-buns-a-blast-from-the-past/e449a57b-dcdd-408a-ac61-4a3bd2fc7b01/?utm_term=.ed4e6e2a5c02
