Double chocolate orange cake

Here's my version of the recipe posted by Kelly over at bakedoandmend recently. I've tried to make it a teeny, tiny bit healthier by substituting olive oil for butter and using less sour cream. It was delish, so thanks very much Kelly! I made the full sized version to take to our annual friends' Christmas dinner on Saturday night and then made it again using half the recipe for when my family came over for lunch today. It went down really well on both occasions. There's still some left over for dinner....! (God, I really need to cut down on all the bad food in the run up to Christmas. Meh, I'll just do it after New Year!)
