Preheat oven to 350 degrees F. Line a cookie sheet with parchment paper and set aside.

In a large mixing bowl, cream together butter and both sugars.

Add egg and vanilla extract and mix thoroughly.

Next, add all dry ingredients: flour, baking soda, salt, cinnamon, nutmeg and rolled oats. Combine well.

Roll the cookie batter into one-inch spheres and place on lined cookie sheet. 12 should fit on nicely on a baking sheet.

Flatten each cookie dough sphere slightly with a fork.

Bake for 8 to 10 minutes. Allow to cool on a wire rack before serving.
