The universal Czechoslovakian cake, called Bublanina, varies with the season and the fruit that is available. It’s a bit like a coffeecake in texture and is probably why it is sometimes served as a breakfast pastry. Commonly used fruits are raspberries, sweet cherries, tart cherries, plums, nectarines, apricots, strawberries and blueberries.
The name Bublanina comes from the Czech word for bubble and might refer to the fact that the cake batter bubbles up around the fruit, almost enveloping it.
