Simple Tip on Boxed Cake Mixes

My girlfriend's dad was a baker and taught me these tips:

Use some of the boxed cake mix instead of flour to dust the cake pan when it calls for dusting the pan with flour when making a boxed cake mix. The taste is more consistent and you don't have patches of dried, white flour on the cake. Also, add shortening to frosting for a fluffier (though not healthier) frosting.
