Stir together the oats, cocoa powder and protein powder in a large bowl. Next stir in the peanut butter, honey, chocolate chips (if adding I like to start with about 1/4 cup) and vanilla. Add chia seeds and flaxseed with the wet ingredients if desired. Stir until smooth.
Line a small baking sheet with parchment or wax paper. Using a small cookie scoop (2 teaspoons), scoop out 40 balls. Place in the refrigerator for at least 10 minutes, or until ready to eat.
Notes
Note: If you add extra ingredients and the mixture feels to dry, add a Tablespoon more of peanut butter and 1/2 tablespoon of honey.If it feels too sticky, add a Tablespoon or two more of oats or protein powder.Freezer Instructions:If you'd like to store in the freezer, place pan in freezer for 10-20 minutes and then transfer balls to a zip top bag or freezer container. Taste best when slightly thawed from freezer or from the refrigerator.
