Method
 

Preparation
  1. Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper.
  2. In a bowl, whisk together the rolled oats, all-purpose flour, baking soda, salt, ground cinnamon, and ground nutmeg.
  3. In a large bowl, cream the softened butter with light brown sugar and granulated sugar until light and fluffy.
  4. Beat in the eggs and vanilla extract.
  5. Gradually add the dry mix to the creamed mixture, beating on low until just combined.
Baking
  1. Drop rounded tablespoons of dough two inches apart onto prepared sheets. Flatten slightly with the back of a spoon.
  2. Bake for 10–12 minutes until edges are golden, but centers are still soft.
  3. Let cookies cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.
Icing
  1. In a bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth and glossy.
  2. Drizzle or spread icing onto cooled cookies and let set for about 20 minutes.

Notes

For creamier cookies, use quick oats and slightly underbake. For a healthier touch, replace half the butter with applesauce.
