Piano Key Banana Cake Roll

Overview

I have made cake rolls many times, but usually only the simplest ones. There are very few cake rolls with patterns like this. It's a bit time-consuming and laborious to make, but it also builds your patience and perseverance. When the finished product is presented in front of you, the exclamation, joy and sense of accomplishment from the heart are also something that others cannot experience.
