1/3 cup oats
1 Tbl. nut butter (I've used peanut butter and almond butter)
1/2 scoop whey protein powder (chocolate or vanilla)
1/8 cup milk
Mix-ins (chocolate chips, raisins, banana, dried cherries, coconut, etc)
In a small bowl add 1/3 cup oats, 1 tbs nut butter of choice and 1/2 scoop protein powder.
Stir to combine and use the spoon to break up the nut butter until you have a nice crumbly mixture.
Add 1/8 cup milk and mix until fully moistened.
Stir in your mix-ins of choice. Plop the mixture onto an appetizer-sized plate and with the back of your spoon, flatten it into a round shape with equal thickness throughout. Put the cookie in the fridge overnight. It will harden slightly from the nut butter and the oats will soften from the milk.
