Peanut Butter Protein Balls (No Bake)

Combine the peanut butter, protein powder, sweetener, and vanilla in a powerful blender or food processor. Process until uniform, scraping down the sides as necessary. The mixture should be very dense, but able to be pressed together. If it's too thin, you can add more protein powder and/or sweetener to taste.

Freeze the dough for about 20 minutes to make the mixture firmer and less sticky.

Use a small cookie scoop (or a spoon) to grab balls of dough. Roll into balls, preferably using cold hands (wash them with cold water first).

Roll protein balls in chopped peanuts to coat the outside. You can enjoy them right away, or refrigerate for 20 minutes to make them firmer. Keep refrigerated.
