Add all ingredients to a bowl and stir to combine. The mixture will be sticky and hard to mix at first. Try mixing with clean hands if a spoon isn't working.
Roll or scoop 1-2 tablespoons of the Smores protein ball mixture into balls and place on a parchment paper-lined sheet tray. If mixture isn't sticking, add more peanut butter. If mixture is too sticky, add more oats.
Freeze protein balls overnight or until frozen. Then place in an airtight container or freezer bag. You don't have to freeze the protein balls, but they keep longer this way. Store in the fridge for up to a week if you do not freeze them.
Notes
It's not required to freeze the smores protein balls. However, I've found that they store better and last longer if frozen.
