I don't know if they now come with the lightbulb, but make sure she has one when she sets it up or you'll be like me, driving to Rite Aid to buy the bulb on Christmas day. LOL.

Yes, we used the regular cake mixes, you just have to modify the recipe unless she wants to bake a TON of little cakes. I would definitely suggest it - there is a reason this toy has survived so long. It's wonderful.
