Koláč – traditional czech pastry

The black is poppyseed, the white one is with quark

You bought it without knowing? :))

It’s koláče (pronounce ko-laa-che), dark one looks to be with poppy seeds (they’re slightly crushed and made into a kind of a paste) and the light one with slightly sweetened quark. The light stuff on them is a mixture of flour, butter and sugar in 1:1:1 ratio.
