Mix the butter, peanut butter, and vanilla together in a food processor until smooth.

Add the protein powder and powdered sugar and blend/mix until crumbly. The mixture will be slightly dry, but you should be able to use a spatula to press everything together. (If your mixture is too dry, add 1-2 teaspoons of water.)

Divide the mixture into 16 small balls, 21-22g each. Roll each ball between your palms to smooth and place on a parchment lined baking sheet that can fit in your freezer. If a ball is crumbly or falling apart, squeeze it together in your hand and continue working it together until you can roll into a smooth ball. Freeze the balls for 15-20 minutes.

Microwave chocolate chips in a small bowl in 15-20 second intervals, stirring at each interval, until melted and smooth.

Stick a toothpick in a peanut butter ball and dip in the chocolate. Smooth the toothpick hole with your fingers after removing.
