The Best Iced Oatmeal Cookies

The deliciously chewy texture of these frosted oatmeal cookies comes from the partially processed oats, which build their structure while also contributing to that old fashioned flavor. These cookies can be baked up more chewy or more crisp, whichever you prefer.

If you’d like these iced oatmeal cookies to be more soft and chewy, then bake them near the lesser amount of time, and for a crispier cookie bake them for the greater amount of time.

Do I Have to Use Old-Fashioned Oats?

Yes, old-fashioned oats are a must for this oatmeal cookie recipe. You should not use steel cut or instant oats for this recipe.

What Type of Milk is Best for the Icing?

You can use any milk you have on hand to make the vanilla icing. If you’re using a non-dairy milk, make sure it’s unsweetened and unflavored.

How to Store Cookies

Once the icing is fully set on these frosted oatmeal cookies, you can store them in an airtight container at room temperature.

Tips for the Best Iced Oatmeal Cookies

  • Let the cookies cool completely before icing them. If you ice them warm, the icing will slide right off the cookie.
  • The butter should be room temperature before you whip it with the sugar.
  • Let the cookie dough rest for 10 minutes before scooping it into balls.

Icing

  • Cheryl Hargett: Will this icing set up hard, too? That’s the kind I’m looking for.. November 28, 2017 at 8:22am Reply

  • Gayle: Jaclyn: I was looking for a cookie icing recipe. My husband loved the store bought iced oatmeal cookies. However, he is recovering from a triple by-pass operation two weeks ago. He told me to get him some more at the store. I said “NO” you are not going to eat those. Too much junk in them that you really don’t know what you are eating. I already had another recipe made up when I found your site. Your recipe sounds soooo much better with all of the spices that are in them. I will be making yours for sure. Home made is always better and can’t wait to try yours!! November 7, 2015 at 3:04pm Reply

  • Linda: These are in the oven now. I don’t have a food processor, so what I did to grind the oats was to use a hand-held herb grinder that I have, filling each compartment to the top with the oats, and then grinded away. The consistency of the oats was perfect and it was very easy. Here is what I used: http://www.amazon.com/KIND-Kinder-Herb-Grinder/dp/B00K5QF37E. Can’t wait to ice these and eat some! Thanks for sharing the recipe! September 6, 2015 at 1:14pm Reply
