Combine whey powder and chopped ginger in a medium bowl. Use your fingers to break apart the ginger pieces and coat in whey powder, so they don’t all stick together.
Add all other ingredients except garnish. Stir with a wooden spoon until everything is well incorporated. If the mixture is too dry, add a little more nut butter. If it’s too oily, add more coconut.
Form into 1-inch balls. Place additional coconut in a shallow bowl or plate and roll the balls in it to coat.
