To a large bowl, add the oats, peanut butter, honey, chocolate protein powder, and cocoa. Mix with a fork until everything is combined.
Gently mix in the mini chocolate chips.
Scoop out 2 tablespoons of the mixture and roll it into balls about 1 ½ inches in diameter.
Serve immediately, or place them on a baking sheet lined with parchment paper and freeze until solid. Then transfer to a freezer bag and freeze for up to 2 months.
