Place the banana in a medium mixing bowl and mash with a fork until smooth.
Add the peanut butter, honey, and vanilla extract to the mashed banana and stir until combined.
In a large mixing bowl, stir together the rolled oats, protein powder, ground flaxseed, cinnamon, and salt.
Add the banana mixture to the dry ingredients and stir until a thick, slightly sticky dough forms.
If the mixture is too soft to roll, refrigerate for 10 minutes.
Scoop approximately 2 tablespoons of the mixture and roll between your palms to form a ball.
Place the ball on the prepared baking sheet and repeat with the remaining mixture to make approximately 18 balls.
Refrigerate for 30 minutes or until firm.

Tips and Tricks
Use a Well-Stirred Peanut Butter - Natural peanut butter can separate in the jar. Stir it thoroughly before measuring so the mixture doesn't become too oily or dry.Adjust the Consistency - If the mixture seems too dry or crumbly, add a teaspoon of milk at a time until it holds together. If it's too sticky, add a small amount of rolled oats.Choose Your Protein Powder Carefully - Whey and plant-based protein powders can absorb moisture differently. A powder that works well in shakes may make these protein balls softer or firmer than expected.Keep the Sizes Consistent - Use a cookie scoop or measuring spoon to portion the mixture. Similar-sized balls will have more consistent nutrition per serving.
Storing
Refrigerator - Store the protein balls in an airtight container in the refrigerator for up to 5 days. Keep them chilled until ready to serve.Freezer - Place the protein balls in a freezer-safe container or bag with parchment paper between layers. Freeze for up to 3 months for best quality. Thaw in the refrigerator before serving.
