I use protein powder in the Cookie Dough Bites recipe posted here and I also use it in shakes. Other than that, the only other time I use it is in Protein Pancakes.
In a small, personal size blender, I mix 1/4 cup egg whites, 1/4 cup oats, 1/2 banana and 1 scoop protein powder. Whip it all up to make a batter and then I cook it in a non-stick pan over medium heat. It helps to cook it with a lid on so the top starts to cook before you flip it....otherwise when it's ready to flip, the top is still runny and it ends up becoming a big mess!)
