I add the protein powder when I make pancakes for my girls along w/whole eggs and whole milk - complete breakfast: carbs, protein and fat.
As for teh denatured part...I dunno. I do know that Universal makes a protein powder designed specifically for baking. When I can afford it (money's a little tight 4 me these days) I put it in the girls' pancakes and mix it into my oatmeal. It comes in YUMMY flavors like strawberry, banana, blueberry and applecinnamon.
