It depends on how the cake was before it was heated. If the cake was raw to begin with and the cake is baked, then yes, it is a chemical change because yeast is making the cake rise. If it was an already baked cake and you are just heating it, then I am not so sure. I don't think it changes at all. Then again, if you are burning the cake, I guess it is a chemical change because fire is making it burn.
