Did you know you can substitute ingredients like applesauce, Greek yogurt, and even diet soda in place of the oil and eggs called upon for the traditional boxed cake mix? It's true, and doing so will save you quite a bit of calories and fat grams.

So then comes the big question: "But, does it still taste as good?"

Watch as I challenge my friend, Brett (yes, that Brett), to a skinny cupcake taste test to see if he can discern the difference between each substitute.

(Note: my personal favorite was the Greek yogurt — but they were all quite delicious!)

Want to try it for yourself? Each substitution is listed below. Please refer to the cake mix box for approximate cooking times.
