Oh my gosh Steem it GETS me! I also made crypto-cookies, though I think yours really take the cake (or cookie?).

First row: Civic, Bitcoin, one of the derpy bitcoin forks (probably gold) and I think QTUM. My 5 year old made that one.

Second row: Steem, Ark, Ethereum and Ripple (it looks like... something else, I know).

And lastly at the bottom is good ol' Litecoin and Dash.

As you can see, frosting is a very difficult medium- I think your idea is probably a better angle!
