This cake looks like it belongs in a baby's pack n play with the simple shapes and primary colors. This would make a nice first birthday cake. Can't you see a sweet tot smashing fistfuls of this beauty into his face? Awwww.
Sure there are all sorts of edible flowers but have you actually eaten them? I have, they taste like, well, like flowers. Wouldn't you rather eat something that looked like a flower but tasted sweet? Of course you would.
Sometimes a meal is so delicious and satisfying that you just want to eat the entire plate and the table cloth and flatware and everything. In my family when food is especially tasty we say that we just want to "rub it in my hair".
