Granted, I'm an atheist Jew (atheist by choice, Jew by trade) but Christian Cupcakes have got to be some sort of mortal sin. You would be effectively eating the cross, the lamb and the bible. Is that kosher? Or is it the same thing as say, Gingerbread Punks?
But the bigger sin here has got to be that you need a "kit" at all. This site has a bevy of adorable looking bible inspired cupcakes and it's all D.I.Y. and stuff. How biblicious is Jonah the Whale?
