I've never thought of decorating a peanut butter cup with white chocolate dyed with food coloring. These were made for Earth Day, but think of all the other possibilities. You could put bunnies or trees or monkeys on there and it would be just darling.
What a lump of cuteness! Slap a kawaii face on an amorphous blob and I'll melt. I'm such a softie. Honestly, this could be a marshmallow, just a cylinder of puffy sugar, and I would still coo over it. Also, I think this cake would be an adorable hat. It would have to be about 4 inches across and have a pretty ribbon to tie it on. I'd wear it every day.
