About two years ago I had to make a cake for a kindergarten graduation party of my twins — the boy and the girl. I didn't have much time for something exceptional, but still wanted a special and unforgettable cake. Also, I wanted that each of my younger children can feel very special and unique. We had a few ideas, but eventually had chosen this one — a cake that symbolizes the Day and Night, Water and Earth (like Yin and yang for kids :). So, everybody got their own special half, although both make the whole cake :) All in all, the twins liked it, and that's what really matters. I used a sponge cake and some colored cream for decorating.
