Prepared rugelach can rest in the fridge for up to 24 hours, noting that the sugar in the filling may get slightly "wet" as it sits. The dough won't get soggy, but the rugelach may be slightly sticky and/or the filling might leak out of the cookies a bit. If an overnight rest works best for your schedule, feel free to give it a try. The cookies will still turn out delicious. Otherwise, you can refrigerate just the dough and roll out/fill the rugelach the next day. Happy baking! Kye@KAF
