In a large mixing bowl, combine rolled oats, almond butter, honey, vanilla protein powder, and peppermint extract. Mix until you achieve a cohesive dough.

If the mixture appears too dry, gradually add almond milk, one tablespoon at a time, until the dough holds together properly.

Fold in mini dark chocolate chips, ensuring they are evenly distributed throughout the mixture.

Roll about one tablespoon of the mixture into a tightly packed ball. Repeat until all mixture is formed into balls.

Refrigerate the protein balls for at least 20 minutes to firm up.

Store in an airtight container layered with parchment paper to prevent sticking.
