Soft, slightly crisp oatmeal cookies iced with a simple glaze are an old-fashioned treat that begs for a glass of milk or a cup of coffee.
I devoured two of these for an afternoon snack with the kids, and then packed up the rest and sent them to work with Sean. I knew I’d be eating them all day long if I didn’t get them out of the house quickly!

Old Fashioned Iced Oatmeal Cookies
Ingredients
- 2 cups old fashioned rolled oats
- 2 cups all-purpose flour*
- 1 tablespoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon kosher salt
- 2 teaspoons cinnamon
- ½ teaspoon ground nutmeg
- 1 cup butter softened
- 1 cup light brown sugar
- ½ cup white sugar
- 2 eggs
- 2 teaspoons vanilla extract
*Gluten-Free Alternative
- 1⅓ cups brown rice flour
- ½ cup potato starch
- ⅓ cup tapioca starch
- ½ cup rolled oats additional for GF version
Icing/Glaze Ingredients
- 2 cups powdered sugar
- 3-4 tablespoons milk
Instructions
- Preheat the oven to 350°F. Place the oats in a food processor and pulse about a dozen times. Be careful not to grind them into flour, you want a variety of oat textures. Pour the oats into a mixing bowl and add the flours, baking powder, soda, salt, cinnamon, and nutmeg. Stir to combine.
- In a separate mixing bowl, beat the butter on medium speed for about 30 seconds. Add the sugars and continue beating until the batter is light and fluffy, about 2 minutes. Add the eggs and vanilla, beat again until combined. Add about ½ of the dry ingredients and mix on low speed to combine. Add the remaining ingredients and mix again until combined.
- Scoop generous cookie dough mounds (about 2 tablespoons worth) onto a parchment lined baking sheet. (Plan for 6 cookies on a tray, they will spread a good bit.) Bake for 10-12 minutes, just until the bottoms of the cookies begin to brown. Do not overbake.
- Remove from the oven and allow the cookies to cool on the tray for at least 5 minutes before transferring them to a wire rack to cool completely. Place the powdered sugar in a bowl and slowly stir in 3 tablespoons of milk. Add an additional tablespoon slowly, stirring until the icing is thin enough to drizzle. Add only enough milk to achieve the correct consistency. Drizzle the icing over the cool cookies. Let dry before storing. Cookies can be kept in an airtight container in the refrigerator or with the lid slightly cracked at room temperature for a crispier cookie. Enjoy!

These look so perfect! And I know all about rushing through a recipe before this kids wake up from a nap.

These cookies are so good. I have been combing the internet for a good gluten free cookie recipe for my kids and these are by far the best!
Monica says
I was really nervous about attempting a GF/DF cookie (I used lard instead of butter and almond milk in place of regular) but this recipe is fool proof! My family is smitten and the fifteen year old kept asking how I was able to eat it! HA! Even if you let them go a little too long in the oven, you still can't mess them up! Thank you a thousand times!

I'm going to have to try them. They look just like oatmeal cookies that were popular when I was a kid and the nutmeg is a great addition too.
