Gluten free German Chocolate Cake

This recipe is adapted from David Lebovitz's german chocolate cake recipe.  It is so moist, so delicious!  The best chocolate cake I have ever had.  Next time I might decrease the amount of sugar by 1/4 C though.  We don't tend to go for really sweet stuff.  I didn't use David's recipe for coconut filling, mostly because I was out of cream.  So I used the recipe in Crazy about Cupcakes for coconut filling, and everyone loved it. 

German Chocolate Cake
2 oz bittersweet chocolate
2 oz unsweetened chocolate
6T water
8oz butter, unsalted
1C sugar
4 egg yolks
1/2 C each of oat flour, tapioca flour, rice flour and buckwheat flour
1/4 C flax meal
1 t baking powder
1 t baking soda
1 1/2 t salt
1C yogurt
1 t vanilla
4 egg whites and 1/4 C sugar

Preheat oven to 350 degrees.  Butter and flour (I used cocoa powder) two 9 inch round cake pans.
Melt the chocolate and water together.  Let cool.
Beat the butter and sugar together until light yellow and fluffy.  Add in chocolate and then the egg yolks.
Mix the flours, flax, baking powder, baking soda, and salt together.  Mix in the chocolate and the yogurt/vanilla in batches until smooth.
Beat the egg whites and sugar until double volume.  Fold into the batter.  Pour batter into cake pans and bake 45 minutes.

Coconut Filling:
one can evaporated milk
1 1/2 cups sugar
3/4 cup butter
4 egg yolks
1 1/2 t vanilla
2 C coconut
1 C chopped nuts (we used walnuts)

Combine the milk, sugar, butter, egg yolks and vanilla in a saucepan.  Stir constantly over medium heat until thickened and golden brown (this took forever).
Toast the coconut and nuts in a 350 degree oven.  Mix in with cooled carmelized mixture.

Chocolate Icing:
8 oz chocolate bittersweet
2T corn syrup
1 1/4 oz butter
2/3 C cream

Combine the chocolate, corn syrup, butter in a bowl.  Heat the cream until boiling, then pour it over the chocolate mix.  Let it sit one minute, then stir until smooth.

To put together:
On top of one cake layer spread the coconut filling.  Place other cake over it.  Spread the rest of the coconut filling on the top.  Spread the icing around the sides.
You won't regret making this cake!
