In a blender, combine the sugar, eggs, vanilla, oil, and orange juice and blend them together.

In another bowl, mix the flour and baking powder.

Mix them well, then grease a baking pan with oil and flour, pour in the mixture, and place it in an oven preheated for ten minutes. Bake for 15 minutes at 350°F (180°C), then for about half an hour on medium heat.
