We also have this kind of dessert in sweden called Budapest roll, a traditional version consists of a hazelnut meringue filled with whipped cream and preserved mandarin slices. Nowadays, some bakeries and bakers opt for other fillings instead, such as fresh raspberries or strawberries.😊😊
If you want to reduce cracks in the cake, roll it up with cellophane while it's still warm, then give it longer to cool before you unroll it and add the fillings
