I haven't had these since I was a kid & my wife wants them for
tomorrow's desert.

It would make life easier if I could bake them today- cool- and store
in a sealed container. [more time today- and if I screw them up I can
try again]

Will this hurt them? Should I do them tomorrow morning instead?

Plan is to fill them with custard just before serving- and have David
Lebovitz's hot fudge and candied almonds on the table.
