Melt peanut butter in the microwave for 30-45 seconds or until it is easily stirred.
Mix together protein powder, oats, and peanut butter to create the batter. Refrigerate for 1 hour to allow mixture to firm.
Once firm, roll into 6 equal sized balls. Insert a paper straw (cut in half) into each ball to create the pop stick.
Melt dark chocolate in a small bowl in the microwave. Dip each ball into the chocolate and coat evenly. Top with sprinkles and refrigerate for a few minutes to harden. Serve chilled and enjoy!
