Ingredients

  • 1 1/2 cups old-fashioned oats
  • 2 cups all-purpose flour
  • 2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1 1/2 tsp ground cinnamon
  • 1/2 tsp ground nutmeg
  • 1 cup butter, softened
  • 3/4 cup granulated sugar
  • 3/4 cup brown sugar
  • 2 large eggs
  • 2 tsp vanilla

Icing

  • 2 cups powdered sugar
  • 3 tbsp milk

Instructions

  1. Pour oats into a food processor and pulse until partially ground, about 15 seconds. In a mixing bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg and ground oats, for 30 seconds.

  2. In the bowl of a stand mixer, whip butter, granulated sugar, brown sugar until light and fluffy. Add in eggs one at a time and then add vanilla.

  3. Slowly add your dry ingredients and mix just until combined. Then place the cookie dough in the refrigerator to chill for at least 30 minutes.

  4. Bake cookies at 350 degrees for 11-15 minutes. Allow the cookies to rest on a baking sheet several minutes before transferring to a wire rack to cool completely.

  5. To make the icing, whisk together the powdered sugar and milk in a mixing bowl. Dip or spread this icing on your cooled cookies. Return them to the wire rack and allow the icing to set. Store in an airtight container at room temperature. Place in the refrigerator for longer storage.

Recipe Notes

Make Ahead & Freezing Instructions:  You can make the cookie dough and chill it in the refrigerator for up to 4 days.  Allow to sit at room temperature if the dough is too difficult to scoop right out of the refrigerator.  Baked cookies with or without icing freeze well for up to 3 months.  Unbaked cookie dough balls freeze well for up to 3 months.  Bake frozen cookie dough balls for an extra minute or two, there is no need to thaw prior to baking.
