Mods if this is the wrong place to post this I'm sorry and feel free to move it as you wish to it's more appropriate place.
But my question is, I want to make a cake for the boys for their birthday on tuesday but I don't want to make a completely doggy one, like made of beef or liver or what not. I looked in the recipe forum and they mostly talk about those kinds of cakes. I wanna fix something me and hubby can share with them too.

So my question...is it ok to fix a regular cake for them (like plain vanilla or yellow cake) and just not put any icing on it or get some kind of other toping for their part? I didn't know if they could have that kind of food. I mean it's only once a year, I think they disserve it for their b-day. I just want to know if the ingredients in say a Betty Crocker cake mix will hurt them? Sorry if my question is a bad one I just want my babies to have a yummy cake. Thanks!
