I made this Butterfly Cake for my sister who passed away for her birthday. She loved butterflies. I baked 2 round cakes and let them cool completely. After they cooled, I cut them in halves and positioned them where they would look like wings. I used twizzlers for the antennas and used edible flower sprinkles for the outline of the wings. I used white icing and coloring to make the purple that was her favorite color.
I am so sorry about your sister, im sure she would of loved the cake as it is beautiful.
