    Ingredients You Need 

    Oatmeal Cookies

    • all-purpose flour, spooned and leveled
    • ground cinnamon
    • baking soda
    • salt
    • unsalted butter, softened
    • brown sugar, packed
    • egg
    • vanilla extract
    • quick-cooking oats, I used 1 minute quick Quaker Oats 

    Vanilla Icing

    • powdered sugar
    • whole milk or milk of choice 
    • vanilla extract

    How to Make Iced Oatmeal Cookies

    1. Preheat the oven to 350°F. Line baking sheets with parchment paper, set aside.
    2. Whisk together the flour, cinnamon, baking soda, salt, and nutmeg and set aside.
    3. Using mixer, cream together the butter and brown sugar for 2 minutes until light and fluffy. 
    4. Mix in the egg and vanilla until fully combined.
    5. Add the dry ingredients to the wet and mix until just combined. 
    6. Add the oats and mix in until evenly distributed.
    7. Using a small, medium or large cookie scoop, place scoops of cookie dough on the baking sheets 2-inches apart. Bake until lightly golden brown along the edges. Let cool slightly on the trays for 2 minutes, then transfer to a wire rack to cool completely. The cookies must be completely cool before icing.
    8. While the cookies cool make the icing by whisking together the powdered sugar, milk, and vanilla. (The icing should be thick, yet pourable so you can dip the cookies into the icing.)
    9. Once the cookies are completely cool, lightly dip the tops of the cookies into the icing and lay them back on the wire rack icing side up. Let them sit to allow the icing to fully set.  To set quickly, place cookies in fridge.

    Baking Sizes and Times

    • Small Cookies (1 tablespoon) Bake 9-10 minutes
    • Medium Cookies (2 tablespoons) Bake 11-13 minutes
    • Large Cookies (¼ cup scoop)  Bake 14-16 minutes

    Storing and Freezing Iced Oatmeal Cookies

    • Store these cookies in an airtight container at room temperature for up to 4 days or store these in an air-tight container in the fridge for up to 7 days. 
    • Store in an airtight container in the freezer for up to 3 months. Remove from the freezer 1 hour before ready to serve. You can also warm in the microwave for 10 – 15 seconds.

    Recipe Tips for Old Fashioned Oatmeal Iced Cookies

    • For best soft and chewy textured cookies, do not substitute steel cut oats for the quick oats in these cookies. They are not processed as finely, so they will not give you the best texture.
    • Over mixing the dough can result in tougher cookies.
    • To get soft oatmeal cookies, remove them from the oven when the bottoms and edges look golden brown.
    • Measure flour correctly to avoid cakey cookies. To avoid this, spoon the flour into a measuring cup and then level it off using a knife.
    • The simple icing should be somewhat thick, so that it will set up firm. If it’s too runny, it won’t set very well, so if it is, add some more powdered sugar to get the right consistency.
