My 2 Best Tips For Making This Iced Oatmeal Cookies Recipe
- Classic Crackled Top: The signature crackled top comes from the proper consistency of dough and baking temperature. Make sure your butter is properly softened, and don't skip the 10-minute rest period, which allows the oats to absorb moisture. When baking, the outside of the cookie sets before the inside is fully cooked, creating that characteristic crackled appearance when the inside expands.
- Don't Over-Process Oats: The key to the perfect texture is leaving some oat pieces larger than others. Pulse the oats in short bursts until they're coarsely ground with some visible pieces remaining. This creates the signature texture that makes these cookies special!
These cookies offer the best of both worlds with slightly crisp edges and wonderfully chewy centers. The warming spices perfectly complement the hearty oats and sweet icing.
The distinctive crackled top covered with thin white icing makes these cookies instantly recognizable and absolutely beautiful. They look like they came from a high-end bakery but require minimal decorating skills!
The dough can be prepared ahead of time and refrigerated, allowing you to bake fresh cookies whenever the craving strikes. They also freeze beautifully both before and after baking.
These cookies are universally loved by both kids and adults alike. They're perfect for bake sales, holiday cookie platters, afternoon tea, or simply enjoying with a glass of cold milk.

Iced Oatmeal Cookies
Ingredients
- 1 ½ cups old-fashioned oats
- 1 cup butter (softened)
- ¾ cup granulated sugar
- ¾ cup brown sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 ½ teaspoons ground cinnamon
- ½ teaspoon ground nutmeg
For the icing:
- 2 cups powdered sugar
- 3 tablespoons milk
Instructions
- Add the oats to a blender or food processor, and blend until the oats process into an oat flour, about 30 seconds. It's okay to have a few chunks left in the oats; they do not need to be ground into a super-fine flour.
- In a large bowl, beat together the butter, granulated sugar, and brown sugar until light and fluffy, about 3 minutes. You can use a stand mixer with the paddle attachment, if you'd like.
- Add the eggs and vanilla, and beat to combine.
- Add the ground oat flour, all-purpose flour, baking powder, baking soda, salt, cinnamon, and nutmeg. Stir to combine well.
- Let the dough rest for 10 minutes, giving the oats time to absorb some of the liquid.
- Preheat the oven to 350°F, and line a baking sheet with parchment paper or a baking mat.
- Scoop a generous tablespoon of dough into your hands, and roll it in to a ball. This will help your cookies to be very round when baked.
- Place on the cookie sheet 2 inches apart, and repeat with remaining dough.
- Bake for 11 to 13 minutes, or until the edges are light brown. If you like a crisper cookie, bake them a bit longer until the whole cookie is a light brown.
- Remove from the oven, and let the cookies cool on a wire rack.
- To make the icing, stir together the powdered sugar and milk to form a thin icing.
- Hold onto the cookie, and dip just the top into the icing. Let the icing drip off, and then return the cookie to the cooling rack, icing side up. Repeat with remaining cookies.
- Enjoy right away, and store extras in an airtight container in a single layer. The icing can make them stick together if you stack them.
Notes
- Make sure cookies are completely cool before applying the icing. If cookies are even slightly warm, the icing will become too thin and run off instead of creating that beautiful finish.
- The perfect icing should be thin enough to dip but thick enough to set opaque. If it's too thick, add milk a few drops at a time. If it's too thin, add more powdered sugar. When dipped, you should be able to see the surface of the cookie through the wet icing, but it will dry solid white.
- Allow at least 2 hours for the icing to fully set before storing. For faster setting, you can place the cookies in the refrigerator for about 30 minutes. Once set, the icing should be dry to the touch and not sticky.

Recipe FAQs
While old-fashioned oats are preferred for their texture, quick oats can work in a pinch. Since quick oats are already partially processed, blend them for less time—just a few pulses should do. The texture of your cookies will be slightly different but still delicious. Avoid instant oatmeal packets, as they contain additives and sweeteners.
Sure! While the icing adds that classic finishing touch, these cookies are delicious even without it. If you prefer less sweetness, you can skip the icing or drizzle just a small amount on top rather than dipping the entire surface.
