How to Make Iced Oatmeal Cookies
Prep. Preheat oven to 350 degrees. Add parchment paper to a baking sheet and set aside.
Prepare the dough. Place oats in a food processor and pulse a few times to make a coarse mix (not fine grind). In a large mixing bowl, add oats, flour, baking powder and cinnamon and set aside. In a separate bowl, cream the butter and both sugars using an electric mixer until light and fluffy. Fold in the wet ingredients into the dry ingredients until combined.
Shape and bake the cookies. Take 1 ½ tablespoons of dough and roll it into a ball. Place the cookie balls on lined baking sheet and press down lightly. Bake for 12-15 minutes. Remove from oven and cool completely on a cooling rack.
Ice the cookies. Combine powdered sugar, milk, and water in a bowl. Dip the cookie tops into the glaze and place aside to set. Let the glaze harden about 10 minutes and serve!
