Cake Recipe Needed!

[NotQuiteCockney]

I want to make a cake for company. One of the guests can't have wheat. So I'm thinking about making a polenta cake, but all the recipes I can find involve butter. She can't have dairy! I'd rather not use marg (oh, and anyway, she can't have soya - are there soya-free dairy-free marg?), what with it being gross and all.

Does anyone have a no-dairy polenta cake recipe? (Or a tried and tested wheat-free dairy-free cake recipe, I guess? But I'd rather not start mucking about with rye flour etc - at least I know I'll use cornmeal for other things ...)

I'd really like to do something nice for this little girl, her diet is really restricted, and I want to serve a nice dessert she can have.

(I guess I can fall back on coconut-milk rice pudding if I must ...)

Oh, I like baking, and like a challenge. And I can't stand the idea of serving a treat that is only for the other kids.

I am thoroughly that it took me a while to work out a 'normal' tea that would meet her criteria. (Did I mention: no potatoes. no tomatoes. no beans. no pulses.?!?)

(Almost all my 'normal' baking recipes are dairy-free, as my ex-best-friend's DS1 was severely dairy-allergic. Actually, I have to start doing nut-free vegan baking for the co-op sometimes, must have a think about how to do that, without compromising my 'I hate marg' principles ...)

Ha. She can have almonds, but her big brother can't. I think I will make this cake anyway - I've asked the mum if that would be ok.

Hmm, I found this . Avocado oil?!? I'm dubious about recipes tied to specific ingredients, but tempted all the same. Maybe for another day.
