Oil-Based Cakes

Cakes made with oil have the advantage of staying moist even when cool, whereas cakes made with butter seem heavier when chilled because the butter hardens. When oil is used to bake a cake, it is usually whisked with whole eggs. The egg-oil mixture is then gently stirred with dry ingredients (usually flour, sugar, baking powder, and salt) and any other ingredients, such as carrots, bananas, or pineapple, that are added for texture and flavor.
