polylithic cake

Phoebe's 18th birthday cake. Last year or the year before when I showed what she'd made, I got a few messages saying something like, 'Phoebe makes her own birthday cake?' as if it were somehow odd that this should be the case. I can tell you it's been this way for many years, as I am positively excluded from the process and Phoebe is perfectly happy to make some mad, happy cake on her own.  

She was 18 yesterday and made a huge polylith of a cake made up of rainbow layers cemented with white buttercream and sprinkled with Rainbow Nerds.

This is all that was left this morning after a very noisy evening. I'm glad I can send her off into the world without ever having to worry whether she will be cakeless on her birthday.
