I have not yet made these, but was lucky enough to have them made by my grandmother herself. As kids I think we snuck half a dozen or so before any meal. She always made them with prunes (and we loved them), but they'd be good with any fruit filling. If you've never had a kolache, they're great!
my dh is czech and his mom makes these she uses solo brand filling for the fruit it comes in different flavoring like poppyseed and apricot and cherry thank you for posting this dee
