First of all: as far as I'm aware - you can't actually bake birthday cakes.
Second: whicih game are you using? Also, your baby might not be close enough to his/her birthday and therefore you can't make it grow up if it's not close enough to it's birthday.

Are you talking about Sims 3 or Sims Freeplay ?
(this is the Sims 3 section)
Good Luck and Happy Simming
