Chocolate cake recipe for celiac people?

I am tired of doing without cake when it is my birthday. I used to love chocolate cake and would like to bake a birthday cake for my birthday but I really need to find a recipe for cake that is gluten free and is safe for anyone with celiac.

I also don’t really want to pay for a recipe book just for this one thing but of course if there are any recipe books with just caked and puddings for people with celiac I will be willing to take a look at them.

I love cakes, I am starting to be really tired of being allergic to wheat!
