With a tasty and easy to make recipe like these iced oatmeal cookies, you’ll wonder why you bothered buying them from a store in the first place. These cookies taste so great when they’re fresh and warm, but they also go great cold with a glass of milk!
How to Make Iced Oatmeal Cookies
- Preheat your oven to 350 degrees F and line your baking sheets with parchment paper.
- Place your oats in a food processor (affiliate link) and pulse 10-12 times. The idea is to break up the oats to create a variety of textures without turning it into ground oat flour.
- In the bowl of a stand mixer, beat your butter, brown sugar, and granulated sugar until they’re light, about 2-3 minutes.
- Add in the eggs and vanilla and then mix again. Scrape the bottom and the sides of the bowl.
- Add in the oats, flour, baking powder, baking soda, salt, cinnamon and nutmeg, and mix until combined.
- Scoop 1 ½ to 2 tablespoon-sized balls of dough and place onto the baking sheet, spacing them 3 inches apart so they can spread when baking.
- Bake for 10-12 minutes until the edges are just beginning to brown. The centers will still look soft.
- Let the cookies rest for a minute or two before transferring to a wire cooling rack and allowing to cool completely.
- Make the icing by whisking the powdered sugar, vanilla, and milk in a medium bowl. It should be a thick icing, but still liquid enough to settle when a spoonful of icing is drizzled back into the bowl.
- Give the tops of the cooled cookies a quick dip into the icing and lift them straight up, allowing the excess to drip off. Place the iced cookies back on the wire rack and let the icing set, about 1 hour. Store in an airtight container for up to 1 week.
Can You Freeze Iced Oatmeal Cookies?
Yes, you can! Freezing these iced oatmeal cookies is a great way to enjoy them as a sweet treat whenever the mood strikes. I recommend freezing them for no more than 2 months in an airtight container for the best quality taste.
How Can I Make These Oatmeal Cookies Festive?
Adding a few sprinkles to the icing before it sets is a great way to bring in some color and crunch. You can also add a drop or two of food coloring (affiliate link) to the icing so that your cookies have a fun coloration. This is great for themed parties such as a gender reveal with pink or blue or Christmas with red and green.
