Our little Hispanic store sells these big, pretty boxes of assorted cookies that are nice - they’re the very cheap kind of cookies that always seem made with coconut oil, but nice because they aren’t real sweet.
I looked up your secret cookies. They would be good. Can't go wrong with butter and egg yolks enhance the flavor somehow. Offhand I can't think of a glass but should be able to find something. And they don't need to be rolled.
Hispanics never go nuts on dulce.
