Oatmeal cookies with no flour, cornstarch, or the like

Has anyone made this recipe (from a Trader Joe’s oatmeal bag) or one like it? My intuition is that the results would be a bunch of loose crumbs, like granola.

I have not - but this person did - and has great photos (as well as good comments from other folks who made the recipe.)

Reading the recipe, I think the peanut butter is the magic ingredient, to help everything stay together…

Yeah, I think so. Thanks.
