Cake mix cakes, are commonly made with the same liquid fat, and can be prepared either layered, in a loaf pan, or as a cupcake. The fat and sugar are not "creamed", but rather the cakes are mixed using the One or Two Bowl or Muffin Mix Method. Oil-shortened cakes instead rely on chemical leaveners such as baking powder and/or baking soda or physical leavening from whipping air into the batter, especially egg whites, if beaten alone with sugar and folded into the batter at the end of mixing.

 The liquid oil acts more rapidly than softened butter to coat the wheat flour's gluten forming protein molecules, rendering them tenderer by preventing the formation of gluten which makes the cakes tough. The key is to not add too much oil, otherwise the cake becomes too heavy and compact, or worse, greasy.
