Tips:
1. Squeeze the remaining cake batter, you can mix it directly into the batter of the back cake body, or you can use a paper cup to bake a small cake separately;
2. Don't wait for the baked cake to be completely cold before rolling it, it will crack easily;
3. When spreading the cream, pay attention to leaving a certain space at the end of the cake. In addition, it can be slightly thicker at a distance from the head. The fruits are also placed in this position, so that it will be easier to roll;
