How to Make Chocolate Banana Cake Roll

This is my second attempt at making this cake.The first time, it was a complete failure,forcing me to throw away the cream and chocolate, leaving me heartbroken but also enabling me to learn from my mistakes.
Although I didn’t achieve perfection in this try,it already has a basic form,and I believe that with practice, it will be even better next time. If you like to experiment,I highly recommend trying this cake. My son is now completely obsessed with it.
It can truly be described as rich, mellow, and fragrant.

recipe for the cake roll, and my summary of failed experiences during the process,
I hope they will be helpful to you.
1. The entire preparation process should be kept at a low temperature; it is best to make it in an air-conditioned room.



2. Prepare cool water, hot water, and ice cubes.
3. Chocolate and butter have low melting points; they don't need very warm water; too warm water can make chocolate bitter.
4. In summer, it's best to chill the cream with ice when whipping it, and after making the cream mixture, keep the bowl on ice for chilling.



5. The cake roll is usually rolled when still warm, but for this recipe, we should try to cool it down before rolling; otherwise, if you apply the cream filling while the cake is too hot, the moisture will separate from the cake body, making it difficult to roll.
6. In summer, it's better not to make too much at once,
