Cashew-Macadamia nut butter, almond butter, or any other nut butter (excluding peanut or pistachio)
Unsweetened coconut (optional)
Flax seed (optional)
Honey/stevia (use stevia on Kaufmann 1)
Cocoa or whey protein powder (chocolate or vanilla)
These snacks can be made to your personal taste, using any combination of the listed ingredients. The only important component is that you will need to use approximately the same quantity of nut butter and either coca or protein powder for the balls to have the right consistency.
Aside from that, feel free to add any combination of ingredients listed, additional nuts, and/or dried unsweetened berries.
