From a baking point of view, using a cake mix can make a recipe a lot easier to make. This is because all (or most) of the dry ingredients have already been measured out for you which means, you can simply mix in the wet ingredients. However, using the cake mix to make the donuts will not include the ingredients that would normally be added to make the cake itself. This is because we are making donuts and not cakes. When it comes to the outcome of the finished cake mix donut, you will find that they are still tasty and even, a bit fluffier thanks to the leavening agent used in the cake mix.
