Delicious old fashioned iced oatmeal cookies with cinnamon and a touch of nutmeg. These cookies have a crackly icing on the top adding a fun look and a lovely taste.
These cookies remind me of my childhood. My grandmother and great aunt always had homemade cookies at their houses. My mom also made a lot of homemade cookies, but they never lasted for more than a day. We had six kids plus my mom and dad and those cookies disappeared while they were still warm.
My mom also brought home cookies from the store. She had to keep the troops at home happy and while they weren’t as delicious as homemade cookies, they were still yummy. One of her favorites was an old fashioned iced oatmeal cookie. Her other favorite was coconut macaroons. I have turned these store bought favorites into a homemade treat.
Oatmeal Cookies
I make a lot of cookies, and make my fair share of oatmeal cookies. Some of my favorites include Oatmeal Cranberry Cookies and Oatmeal Chocolate Chip Cookies. And now these iced oatmeal cookies. I don’t think you can ever have too many cookies recipes!
How to make iced oatmeal cookies
- Place old fashioned oats in a food processor. Pulse 3-4 times, just to break up some of the oats.
- Add flour, baking soda, salt, cinnamon and nutmeg. Pulse 3-4 times to mix ingredients.
- In the bowl of a stand mixer, mix butter until soft and light
- Add sugars and mix
- Add eggs and vanilla and mix. Scrape down sides and mix again.
- Slowly add flour mixture into butter mixture
- Scoop batter onto an ungreased baking sheet and bake in a preheated 350 degree oven for 12-15 minutes.
- Allow cookies to cool for a few minutes and then transfer to a baking rack.
The icing
The key to these cookies really is the icing. It’s the signature finishing touch that makes them so special. To make the icing:
- Sift powdered sugar
- Mix in milk – the icing will be thick, almost a glue like consistency
- Take each cooled cookie and dunk straight into the icing, Do not tilt or twist, just a straight dunk in and then out.
- Allow excess icing to drip off.
- Place on a baking rack and allow icing to dry – about 1 hour
To store the cookies
Once the icing has fully dried and hardened on the cookies, you can stack the cookies and store in an airtight container or a plastic storage bag. You can place a piece of waxed paper between each layer of cookies, if desired to help prevent sticking. These cookies will be good for 3-5 days left at room temperature.
To freeze the cookies
These cookies are a great cookie to make ahead of time and freeze. You can freeze without the icing or already iced. To freeze with the icing, make certain the icing has fully dried and hardened. Layer cookies in a freezer safe container. Place a piece of waxed paper between each layer. To thaw, simply pull cookies from the freezer and allow to thaw at room temperature.
Tips for making Iced Oatmeal Cookies
- Use old fashioned oats
- Pulse oats in a food processor to break up some of the oats into oat flour.
- Use a cookie scoop to get evenly sized cookies
- Sift the powdered sugar to remove all lumps
- Keep the icing thick. If needed, you can add a drop or two more milk
- Dunk cookies into the icing straight in and straight out – no twisting!
- Allow excess icing to drip off. I let mine drip for 3-4 seconds
- Make certain icing fully dries and hardens – about 1 hour

The icing sinks into the cookies creating that look. There isn’t anything else on top of the icing.
Enjoy!

June 26, 2020 at 4:52 amI absolutely love oatmeal cookies, and I second your thought that you can never have enough variations! (Laura on the other hand says oatmeal raisin cookies are just cookies that want to be chocolate chip cookies. I disagree!) I love iced oatmeal cookies, and I know a batch of these would be well-received in our house. It would certainly keep the troops of me and Robbie happy! 🙂 Have a great weekend ahead, Kathy!
