Measure out ingredients and whisk together in a large mixing bowl until everything has been incorporated and the mixture becomes dough-like. Be sure to weigh out protein powder. The ingredients will mix together best if peanut butter is stirred and warmed slightly. You can do so by putting jar of PB in a large bowl of hot water for several minutes.
Begin forming balls by rolling a scoop of the dough between two hands. You should be able to make at least 15 protein balls.
Tip: Every protein powder is slightly different. If your mixture seems to dry to hold together you can add a little more peanut butter or honey to the recipe to help bind.
