Come and try my small Czech kolacky cookies made from flaky cream cheese dough! Filled with jam and dusted with icing sugar, they melt on your tongue the moment you put them in your mouth. Kolacky is an original Czech name for small, bite-sized sweet pastries with different kinds of filling. The most common filling is jam, poppy seed, or nut filling. Fresh cream cheese (called tvaroh in Czech) or yeast dough is usually used to make kolacky cookies.
