its called cake mania and you have to bake and decorate cakes, keep impatient customers happy with free cookies, use you money to upgrade you kitchen appliances etc..
Silly game but we had a fun time playing it. I can't imagine many people would really want to play a game like that so she found it at Wal mart for $5.
If you don`t have the DS gaming system, you can also find it on the Shockwave website as a demo, along with a few other cake games.

I`ve played Cake Mania before, it is an extremely fun quick game.
