Old-fashioned iced oatmeal cookies are the perfect after-school treat with a glass of milk. Crispy, chewy cookies coated in creamy vanilla icing.
You might also like my iced molasses cookies, bakery-style snickerdoodles, or chewy chocolate chip oatmeal cookies.

Old-fashioned iced oatmeal cookies are easy to make and are a nostalgic treat. This recipe is an elevated version of my favorite oatmeal cookie recipe, Poor Man's Cookies.
Why I Like This Recipe
- Perfect balance of texture. These cookies bake up with the perfect contrast between a slightly crunchy exterior and a chewy oatmeal interior.
- Simple ingredients. The recipe uses familiar pantry staples like oats, brown sugar, and cinnamon, along with a creamy vanilla glaze. Instead of butter, shortening is used to create a chewy texture.
- Versatile. It’s easy to make a big batch for after-school treats, and the un-iced version even works wonderfully as ice cream sandwich cookies, so it fits multiple occasions and preferences.

Tips and Tricks
- Generic shortening brand. Off-brand shortenings seem to work better in this recipe than Crisco. I'm not sure why, but I'm also not going to mess with it. Just use the cheap stuff.
- Cookie scoop. A cookie scoop makes it easy to bake uniform, perfectly round cookies.
- Ice the cookies while they’re completely cool
Let the cookies cool fully before adding the icing so it sets properly instead of melting into the cookie. This gives you that classic sweet glaze on top with a nice contrast in texture.
Ingredients
- shortening
- water
- sugar: a combination of brown and white sugars.
- vanilla extract: have you ever made your own vanilla extract? It's delicious!
- all purpose flour
- baking soda and salt: for flavor and leavening
- spices: cinnamon and nutmeg
- oats: You can use quick oats or old-fashioned oats. I prefer old-fashioned rolled oats.
- powdered sugar and water: mixed together to make a delicious glaze.

How To Make Iced Oatmeal Cookies

Step 1: In a large bowl, cream shortening and sugars until light and fluffy.
Step 2: Beat in water and vanilla. Combine the flour, baking soda, salt, nutmeg, and cinnamon; gradually add to the creamed mixture, mixing well. Fold in oats.

Step 3: Drop dough onto lightly greased baking sheets or parchment-lined baking sheets using a medium cookie scoop.
Step 4: Bake at 350° for 10-12 minutes or until golden brown.

Step 5: Allow cookies to stand 2 minutes before removing to a wire rack to cool completely.

Step 6: While the cookies are cooling, make a batch of glaze. Stir milk and powdered sugar together. Add water, 1 tsp. at a time until the desired consistency is reached.

Step 7: Quickly dip the top of each cookie in the glaze. Allow excess to drip off.

Step 8: Allow cookies to sit until icing is set.
Iced Oatmeal Cookies FAQs
Yes! You can make the dough ahead and store it in the refrigerator for 2–3 days before baking, or freeze it for longer storage.
Store the cookies in an airtight container at room temperature for up to 3 days. You can also bake the cookies and freeze them (with or without icing) for up to 3 months.
The cookies are still delicious on their own without the glaze.

I made these tonight as we had all the ingredients and it looked like a quick fix for the sweet tooth we all had. Unfortunately for me these were all too sweet. I couldn’t taste the spices and the texture was not what I usually go for, maybe from all of the brown sugar. But I know these would be great for people who like a very sweet cookie!
