This sponge cake is the most simple and the most complicated one at the same time I've ever made. At first I design the paper pieces of the cake pan on my computer, then plotted them in the correct scale. That was the time when I got shocked realizing how tiny these pieces are! Bot I'm not the type giving in and the result was worth all the efforts and time.
Let me introduce you my little sponge cake just from the oven. The frame even burnt my finger!
