Cake kukus ketan hitam putih telur (Egg white & black glutinous rice steamed cake)

This was my first time dealing with black glutinous rice flour. I became interested in this flour after Ummu fatima posted about black glutinous rice flour cake again, again and again. It was so tempting. She also said that it was her family's favorite and always disappeared in no time. Was it that good? hmmmm ...*so curious*
