Mix the oats, whey, almond or oat flour and flax seed. Once combines, add almond butter, applesauce vanilla and honey.
Mash the bananas into the mixture and combine. (note: I like to mash mine first and then add to the mixture for a smoother texture.)
Pour batter into the pan and bake about 15 minutes.
Cut to your desired sized. Since these are packed with protein, a little goes a long way so I like to cut into 18 or 36 pieces, so much smaller than the typical brownie size.
