Surprise! We scoured our favourite food blogs for clever cakes that conceal a world of goodies, from a mountain of M&M's, to a bumper crop of strawberries. There's even cakes that look like mugs of hot chocolate and pints of frothy beer. In fact they're so good, we think they should probably be illegal - and that's no exaggeration. Which one would you like to get your paws on at your next party?
