The dryness/stickiness of the cookie dough can vary depending on the type of protein powder that you use. If the cookie dough is too dry: Add a bit more peanut butter or a splash of milk (can use regular or plant-based milk alternative). If the cookie dough is too sticky: Add a bit of oat flour to the mixture. You can also add in some quick oats, but it will give the cookie dough bites a bit more texture.
