Recipe Notes

* The type/brand of chocolate chips used should be compliant with your personal diet.

**Use plant-based protein powder for the vegan version. When doing so, reduce the amount of rolled oats used to 1 1/2 cup. This is very important as plant-based protein powder absorbs much more moisture than whey. Please note that every type of plant-based protein powder will behave differently so if your base is too dry and won't hold together, add some almond milk gradually until you can easily form a ball with the dough using your hand.
