Notes: It’s extremely important to measure both the oats and protein powder correctly using
this method or a
kitchen scale. (← That’s the one I own!) Too much of either will dry out the cookies and leave them crumbly or cakey instead of chewy.
Instant oats are also known as quick-cooking or minute oats. They come in large canisters, just like old-fashioned oats. They are not the ones in the small flavored packets of oatmeal. To make your own, add the same amount of old-fashioned oats to a food processor, and pulse 10-12 times.

For a stronger spice flavor, increase the cinnamon by ¼ to ½ teaspoon, and increase the nutmeg and ginger by ⅛ teaspoon each.
If the cookie dough is still somewhat sticky after chilling, be patient while flattening it with the spatula on the prepared baking sheet. The somewhat sticky texture results in very soft and chewy cookies. I promise these cookies are worth the effort!
