Rolled oats are oat grains steamed and pressed flat, then cooked into porridge, soaked overnight or stirred into yogurt and baking. These numbers are for the dry oats, before any milk, water or toppings are added.

Weigh the oats dry, then add the milk, fruit, nut butter or honey as their own items.
