Lorna's Gluten Free Orange and Coconut Cake

I've got a couple of friends who are gluten-free. One out of choice which really doesnt make sense; choosing to give up cake! But anyway, every now and then i send cake to their work via my fella to keep them happy. This is the latest to make the trip

Ingredients:
100g ground almonds
70g shredded coconut
150g fine cornmeal/polenta
2tsp baking powder
juice and zest of 2 oranges
270g butter
270g caster sugar
4 medium eggs


Method:
Preheat the oven to 180C. Grease an 8" round deep cake tin, lining with greaseproof as well if you want. In a large bowl, mix together the almonds, coconut, polenta and baking powder. In a separate bowl beat the butter with the sugar until light and fluffly, then beat in the eggs one at a time. Don't worry too much if it splits a bit - a tablespoon on polenta should bring it back together as with a regular cake. Beat in the orange zest.
Pour the dry mix into the buttery mix and add in the orange juice. Mix until well combined. Pour into the tin and bake for about an hour. I baked for 45mins then covered the tin with foil so the top didnt go too brown and baked for another 25 minutes. Poke with a skewer to check if its done. Pop out of the tin and leave to cool on a cooling rack.
When he's nice and cool you can cut him in half and ice with any icing you want. I had a packet of Polish Dr Oetker icing in the cupboard (for reasons i fail to remember) which, from my apt skills on Google Translation, i made up as instructed. I did confirm it was gluten free first. Tasted a bit like hot chocolate, but not so hot...
