If you enjoy baked treats, then the oatmeal cookie e-liquid will be a flavor that you enjoy. Upon smelling the liquid when you remove the lid, there is a distinct note of cinnamon and oatmeal blended together. The spices aren't overwhelming, combining delicately with the other flavors that are in the liquid. There are notes of oats in the liquid as well that blend with the other flavors to deliver an oatmeal cookie taste when you exhale. The oatmeal cookie smell and the taste are what you might experience in your kitchen while you're baking or when you visit a bakery.
