Here is a recipe for a chocolate cake, that won't repel the others.
Flour-less chinese five-spice chocolate cake:
400 g good-quality dark chocolate, finely chopped (I use Lindt’s new 70% Cocoa Specialty Cooking Chocolate)
1 1/4 cup (275 g) castor sugar
1/2 cup (125 ml) water
5 tsp Chinese five spice powder
280 g unsalted butter, at room temperature, cut into small chunks
2 tsp vanilla extract
6 eggs (about 340 g total weight)
If you're in the United States of America for a more complete chocolate cake I'd recommend the Gluten Free Sun Flour Mills chocolate cake mix. The cake made from the mix won first-prize in its section! Even non-gf people loved it! Unfortunately as I'm in Australia it's not easy to get it over here cheaply.
I'd also encourage you to check out http://gfboulange.blogspot.com.au/ for some delicious gluten free bread recipes, some of which I've tried and can tell you they are some of the nicest breads when fresh!
