Regardless of which type of bites you are going to make, begin my combining the dry ingredients together in a bowl, oat flour, protein powder, and cocoa powder if you're making chocolate bites.
Then add the almond butter and start incorporating that with a fork, so it "mooshes" together easier.
Then add the milk. For the chocolate version, because there is the added cocoa powder, you may need to add slightly more milk.
Mix all ingredients together with the fork until everything is incorporated. The dough will be sticky and very thick.
Roll Tablespoonfuls of dough between your palms and place on a parchment-paper lined baking sheet. Like I said, the dough will be very sticky, but wetting your hands often will keep the dough from sticking to your hands.
Once all the dough has been rolled into balls, place in the refrigerator for at least an hour before covering in chocolate, if you desire.
Once you're ready to cover in chocolate, place a Tablespoon of chocolate chips (white or semi-sweet) in a small microwavable bowl with a teaspoon of coconut oil. Heat for 5-10 seconds at a time, stirring in between each interval, until the chocolate is melted completely. Spoon a small amount over each cookie dough bite and place baking sheet back in the refrigerator. This will cause the chocolate coating to harden.
Once hardened, you can then transfer the bites to an air-tight container. But be careful if you need to stack them. They continue to stay sticky on the bottom, so you'll need to layer parchment paper in between.
Will keep in a container for up to a week in the refrigerator.
