    We’ve taken classic cookies to a whole new level! Dipped in vanilla icing and sprinkled with a touch of cinnamon, these old-fashioned iced oatmeal cookies are simply irresistible!

    I’ve always loved making different varieties of oatmeal cookie recipes – whether it be apple oatmeal cookies or pumpkin oatmeal cookies – but, this time, I went back to the basics. Well, sort of.

    Easy Oatmeal Cookies with Icing

    Homemade cookies are always leaps and bounds tastier than anything you can buy at the store. And one of the easiest packaged cookies to recreate is the iced oatmeal cookie! 

    These iced cookies are tender, chewy, and infused with nutmeg and caramelized brown sugar aromas. The simple vanilla glaze enhances the cookie’s natural sweet flavors and altogether they are the definition of simple tasty cookies. With a little something extra!

    Ingredients For Oatmeal Cookies

    ingredients for iced oatmeal cookies - egg, salt, baking soda, vanilla, nutmeg, sugar, quick oats, vanilla extract, flour, butter and brown sugar.

    ingredients for iced oatmeal cookies - powdered sugar, milk and vanilla extract.
    for the icing
    • Oatmeal: Use quick oats to give them a softer, chewy texture. Old fashioned oats can be used if you prefer a coarser, more textured cookie.
    • Flour: Any kind of all-purpose flour will work. You can even use ½ oat flour and ½ all purpose flour if you’d like. As long as it’s measured correctly! For gluten-free cookies use gluten-free 1:1 baking flour.
    • Baking Soda: This is what helps the cookies rise.
    • Cinnamon & Nutmeg: Warm spices add a depth of flavor and are a welcome addition to these iced oatmeal cookies.
    • Salt: It naturally enhances all the other flavors.
    • Butter: Use unsalted butter and let it soften a bit before you mix it in.
    • Brown Sugar: This deepens the flavors of the cookies with a delightful molasses flavor. Brown sugar also adds moisture to the cookies. Use light or dark brown sugar.
    • Granulated Sugar: This sweetens the cookies without the molasses flavor. 
    • Egg: Binds all the ingredients together. 
    • For the icing: Powdered sugar (aka confectioners’ sugar), milk, and vanilla.

    Variations To Try

    1. Any milk can be used including nondairy milk such as oat milk, almond milk, or soy milk for the icing.
    2. Toss in some mix-ins. ½ cup of raisins, dried cherries, or dried cranberries would be great.
    3. You could also do ½ cup of semi-sweet chocolate chips or milk chocolate chips.
    4. Swap the vanilla extract for almond extract for a variation in flavor.
    5. You can use all brown sugar or all granulated white sugar instead of the combination if preferred.
    6. Replace the cinnamon and nutmeg with either apple pie spice or pumpkin spice for a different kind of fall flavor!

    How to Make this Iced Oatmeal Cookies Recipe

    If you have ever made a batch of drop cookies before, then these will be a breeze! Just mix the ingredients, bake the cookies, and drizzle with icing. They are done and ready to enjoy!

    Butter, brown sugar and sugar in a mixing bowl.

    Step 1: In a large mixing bowl, cream the butter and sugar with an electric mixer until creamy. (start on low speed and increase to high speed as the sugar is blended) Keep blending them as you add the vanilla extract and egg until just combined, scraping down the sides of the bowl as you blend. (you can also use the bowl of a stand mixer with the paddle attachment).

    Step 2: In a medium bowl, add the flour, oats, baking soda, and spices and blend. Then add the dry ingredients to the wet ingredients. Stir to combine well.

    Step 3: Use a medium cookie scoop to place cookie dough balls on the baking sheet. Then, use your fingers to press down and flatten the cookies.

    Step 4: Bake for 10-12 minutes until the cookies turn golden brown. Place them on a wire rack and let the cookies cool while you make the icing.

    Step 5: Mix the powdered sugar, milk, and vanilla extract until smooth. Dip the tops of the cookies into the icing and let the excess icing drip back into the bowl.

    Step 6: Sprinkle the cookies with cinnamon and let the icing harden.

    Tips

    • Use a silicone baking mat. This will help prevent too much spreading and make clean-up so much easier. 
    • Remember to flatten the dough. If you don’t flatten the cookie dough before you bake them, they will bake as round balls!
    • Use a cookie scoop to keep all the cookies the same size. This will help them bake evenly. You can make smaller cookies by using a 1 ½ Tablespoon scoop.
    • They are soft cookies, so place them on a wire rack to cool completely before you move them. 
    • If you only have old-fashioned oats on hand, you can simply pulse them in a food processor and pulse the oat a few times to create your own quick oats. 

    FAQ’s

    How do you store homemade iced oatmeal cookies?

    Store the cookies in an airtight container at room temperature for 3-4 days or in the refrigerator for up to a week.

    Can you freeze iced oatmeal cookies?

    Yes, you can. Freeze them in a freezer-safe baggie or container with parchment paper between layers to keep them from sticking. Keep frozen for up to 2 months.

    How many cookies does this recipe make?

    This recipe makes eight large cookies. Again, if you want more cookies, you can make them smaller!

      This cake ice is soft, chewy, and flavored with nutmeg and caramelized brown sugar. A simple vanilla glaze enhances the cake’s natural sweetness and is all in all the definition of a delicious simple cake.
