Gluten and dairy free orange cake

Last part of the meal was dessert and there again I didn't want to use wheat flour or butter, I had a tried and tested recipe but wanted a change, so here goes this new recipe.

Gluten & Dairy free Orange cake

Serves 8

Ingredients

2 oranges
150 gr brown sugar
170 gr almond powder (I use full raw almonds that I grind)
6 egg yolks
6 egg whites
A dash of cointreau or any other liqueur you prefer

Method
Juice and zest the oranges, mix with sugar, almond powder, egg yolks and liqueur.
Beat the egg whites and delicately incorporate them to the batter.
Pour into oiled form (I use a 24 cm/9"diameter spring form cake pan with a layer of parchment paper on the bottom).
Bake into preheated oven at 110 C/230 F for 40 to 50mn depending on your oven.
