Low Calorie Gluten Free Protein Batter! For Muffins/Cakes/Donuts/Pancakes!

 I'm always looking for a cakey protein batter for donuts, muffins, pancakes, etc, but a lot of the time, protein recipes just turn out rubbery and dry! BUTTTTT not this batter! Finally nailed it! Maybe it's because I used the Quest Protein Powder which is a blend of different proteins!
