These were pretty good.  They are very dense, likely due to the oat bran.  ** One caveat  – I think you need to use either soy, rice, or some other veggie protein for these, as it acts as a flour agent.  If you use whey powder, the batter is likely going to be too thin, but you could probably bake in in a pan that way and cut it up. **

Ingredients:

• 2 scoops (60 g) of strawberry soy protein powder
• 1 cup (120 g) of oat bran
• 1 tsp cinnamon
• 3/4 tsp baking powder
• pinch of salt
• 1 tsp vanilla
• 1 small banana (100 g)
• 1/2 cup natural applesauce
• 2 egg whites (56 g)

Preheat oven to 350 degrees.  In a bowl, mix together the protein powder, oat bran, cinnamon, and baking powder.

In a small food processor (or Magic Bullet!), blend together the banana, salt, egg whites, vanilla, and applesauce.  You can just mash the banana and mix everything, but I wanted it really smooth so there would be no banana bits.

Add this mixture to the dry and mix well.  Portion out into 10 equal balls of dough and press flat onto a cookie sheet with parchment or silicone liner:

Bake for about 15 minutes and remove from oven.   This protein powder I have is actually really sweet, so I decided to top my cookie with a little plain cream cheese to eat.

Using protein powder that is 110 calories per scoop and 24 g of protein per scoop, the stats are as follows:

Batch makes 10 cookies (they were about 40 g each)

Each cookie (minus cream cheese) has 80 calories, 1.2 grams of fat, 12 carbs, 2 g of fiber, 7.5 g of protein.

I am interested in trying this with whole wheat pastry flour instead of oat bran.  I think that would make a more cake-like cookie.  Plus, different flavor powders will give you different flavored cookies.
