Add powdered sugar and protein powder gradually and continue mixing.
Freeze this mixture for about 20 minutes so that it's easier to handle.
Scoop out small portions of the mixture and roll them into balls.
Place them on a cookie tray, lined with wax paper and stick a toothpick in the center of each ball. You may need to chill the tray in the freezer for another 10 minutes if the balls have started to become too soft and the toothpick is not sticking securely.
Dip each ball three quarters of the way into a bowl of melted chocolate and place them on a cookie tray, lined with wax paper.
Optional: Dip the ball in chocolate first and then roll them around in a bowl of chopped nuts and then place them on wax paper.
Remove the toothpicks gently and smooth out the hole with your fingers and enjoy!
