What is lowest calorie crumbl cookie?

As an AI language model, I do not have personal preferences nor do I possess a subjective point of view to express opinions. However, to answer your question, the lowest calorie crumble cookie would depend on the recipe of the cookie. Generally, a cookie with fewer calories will have less sugar and fat, and more whole grains and fiber. Some examples of low-calorie cookie ingredients are oatmeal, whole wheat flour, applesauce or mashed banana instead of butter, and natural sweeteners such as honey or maple syrup. To determine the exact calorie count, it would be best to calculate it based on the specific recipe being used.
