How can I get that iconic craggy top iced oatmeal cookie look?
To get that iconic look, you want to lightly dip the cookies into the icing or glaze. I was going for the Crumbl look so I dipped them a little extra in there.
This depends strictly on preference so do whatever you prefer. Dip a little less or a little more depending on your likings 🙂
Can I make smaller cookies with this recipe?
You sure can!
This recipe makes pretty large cookies and if you want to make them smaller you will get about 16 smaller cookies instead of 8 larger ones.
When it comes to baking them, bake for about 8 minutes instead of 10. Decorate as you would the large ones.

- Using a large cookie scooper, scoop out 8 equally sized cookie dough balls, place them on the prepared baking sheet, gently press down on the cookies to about 1 inch in thickness, and bake them in the preheated oven for 10 minutes. Make sure to not overbake them so they stay soft and gooey
- Let the cookies cool down on the baking sheet for 20 minutes then more to a cooling rack to cool down fully.
Make the glaze
- In a medium bowl, whisk the powdered sugar 1 tbsp milk and vanilla together until combined. You can the mixture to be thick and creamy but thin enough to dip the cookies in. If it's too thick add 1 tsp milk at a time and mix.

Notes
- Butter softness matters: The butter should be softened but not melted. If it’s too soft, the frosting will be runny.
- Â
- Fixing a runny frosting: If your frosting looks too liquidy, place the bowl in the fridge for 10–15 minutes, then beat again until fluffy.

So easy to make and delicious! My family has added this recipe to our favorites.
YAY! Enjoy!
I need to double the recipe next time, these were so good. Only lasted 1 day, but were still soft and yummy the next day too. I skipped the glaze because I don’t like frosting, but I think I’m going to try it next time!
i only have quick oats can i use that instead and do i have to change anything.
Yes you can!
Made the tonight and wow….absolutely delicious! This recipe is perfect, no modifications needed!
Thank you so much!
I have tried a lot of oatmeal cookie recipes but this one is the best I have tried. A wonderful simple oatmeal cookie. I am sure you could dress it up with nuts, raisins as well, but alone with the icing they are simply delicious. This recipe is a goody!
So glad to hear you enjoyed them, Melisande!
These are definitely a good choice if you have a ton of oats expiring like I did ha ha! Despite not having any chocolate, sprinkles, or any other things little kids normally gravitate towards, my two little ones really liked them! Definitely let your cookies cool completely before icing them as the recipe stated. I got too excited & iced them too early & it soaked in a bit. Totally my fault there! The taste was the same regardless though.
I’ve definitely had a few moments like those lol.
As long as they taste good that’s all that matters!!
These cookies are so easy to make and are SUCH a crowd pleaser! I take them to work for food days – or I pick a different copycat recipe from LOAF – and they get devoured immediately! Thank you so much!
That’s what I like to hear! You’re so welcome Jenny!
So glad I can make our own iced oatmeal cookies now! I had always wanted a recipe worth making and this is it. Quick and easy roo
My cookies are pretty blonde. Any suggestions on where I went wrong? Thanks!
Hi Jenn! If they stayed pretty pale, it could be your oven running a bit cool or baking on a lighter-colored pan. You can bake them an extra minute or two, or bump the oven temp up by 5–10°F to help them get more golden.
I’ve actually made these(added raisins) and a few other of your recipes. They are sooooo good! I will be making more!
Thank you Allie! Sounds delish!
