What are funny things to write on a birthday cake?!
Best Answer - Chosen by Voters
Do a cake up in something from her childhood era, favorite dolls, cartoons, etc. "Never too old."
You could really over decorate the cake and make it full of chocolate sprinkles, toffee shards and everything, and write: "Some things in life are worth over doing-like your Birthday! Happy birthday Lauren!" Or something like that. Wish her Happy B'day from me ! :)
Bake a cookie cake instead...then write: Happy Birthday to One Smart Cookie from another!
Write "Congrats on the sex! Just kidding, HAPPY BIRTHDAY!"
put on the cake "you adopted!!"
Congrats! You're half way to middle age!
