In a medium bowl, mix together the vegetable oil, sugar and eggs. Stir in yoghurt and orange zest. Combine the flour and baking powder; stir into the mixture just until blended. Pour the dough into a greased 22x33cm cake tin.
Bake for 30 minutes in the preheated oven, or until a knife inserted into the cake comes out clean. Poke holes in the cake with a knife, and pour the juice from the oranges over the cake slowly until it has all been absorbed.
For a Halloween cake...
The cake will look dark orange so if you use black decoration on it, it is a perfect Halloween cake
Have made this recipe twice, first i made it into cupcakes and they were lovely, second time used a loaf tin and it turned out very dense. Wouldn't use this tin again for this recipe as also didn't rise as well. Orange flavour is strong but not too overpowering. - 23 May 2010
