Notes: This recipe was specifically designed for whey protein powder. Most protein powders behave differently, especially when it comes to absorbing moisture. If you substitute a different whey-based protein powder than the one linked to in the recipe above, you may need to add more protein powder if the dough is too wet OR a tiny bit of milk if the dough is too dry. Do not substitute plant-based protein powder; it tends to be much more absorbent and will most likely result in dry, cakey cookies.
If the cookie dough looks too dry, add 2 teaspoons of milk at a time until everything comes together. If it looks too wet after letting it rest, add 1 teaspoon of coconut flour at a time until the texture is thicker.
Xanthan gum helps hold the cookies together and make them chewy.
Honey may be substituted in place of the agave.
Swerve and Truvia are both no-calorie, Stevia-based sweeteners. You may use all of one or the other, or you may substitute your preferred granulated sweetener instead.
