so my mother's birthday is rapidly approaching, and she's asked that i bake her a birthday cake. obviously, i don't want to make it too full of sugar or fat or whatever, but i'd also like to avoid adding any kind of crazy chemicals or replacements(ie, no splenda, no margarine, etc)--natural replacements are fine(ie, honey or agave nectar or whatever)...chocolate cake would be preferable, but any "plain" (my mother is not particularly open-minded toward food) would be fine.
thanks!
