Heres a really easy recipe that I've adjusted that I found on the "Bellini Addicts" facebook page. (It can easily be changed to do without a Bellini)
Easy Orange Cake!
1 whole orange cut into quarters (or blended if not using a food processor)
80g sugar (orignial recipe said 200g - but you really dont need that much)
300g Self raising flour (I use 200g white, 100g wholemeal)
Preheat oven to 180deg
Cream the orange and butter together ( to be paste-like) Bellini mix 7sec, speed 8
Add the remaining ingredients and mix until its a cake batter - Bellini 20sec, speed 4
Spoon into patty pans, cook 20 mins on 180 deg.
