From my personal opinion:
Oh my goodness, I cannot recommend these to anyone. They are dry and have the taste and scent of vanilla bubblegum (think old timey-time 80's bubblegum ice cream), and almost cherry-ish. It's not very pleasant considering it boasts that it's "real vanilla".
If you want yellow cake with a nummy icing I'd recommend either making your own or getting a store-bought cake.
The good thing is, these do not contain artificial color, which is a bonus if you have sensitivities or have that kind of allergy.
