If you are a step more than vegetarian and wont consume dairy products either, this is the perfect cake recipe for you. The butter that is traditionally used in cakes is substituted by any clear, refined, odourless vegetable oil, such as sunflower oil. To test if the cake is done, pierce a toothpick through it, if it comes out clean, it is done. Otherwise it needs to be baked for a few more minutes. Avoid using too much baking powder and vinegar to prevent the cake from drying up; however too little will make it harder than desired
