Bake for 1 hour 15 minutes or until a skewer inserted into the cake comes out clean. Allow the cake to cool for a few minutes before turning it out onto a plate or wire rack. While the cake is still warm, brush it with the orange syrup then allow to cool completely before icing (if you wish). Orange syrup : 110g icing sugar 50g orange juice Mix the icing sugar with the orange juice. Set aside until ready to use. This is where growing up with a fellow frosting-fiend for a mother is helpful And now, of course, I get to put as much icing on a cake as I please. Which generally means LOTS of icing. Right now I'm in the apple pie season though, so this will just have to wait... orange cakes are one of my favourites -- and i love using yoghurt or sour cream when i can (i often use them even if the recipe says milk). i agree with you, icing is optional -- i want my cake NOW, i can't be patient enough for icing!
