About this iced oatmeal cookies recipe

The flavour

These cookies are the best oatmeal cookies recipe we have ever tried, so delicious. Don’t let the cinnamon in this recipe fool you, you don’t taste the cinnamon at all. 

Instead, you have this blend of deliciousness and if you had to guess what was in it, it would be a mystery. It does add to the complexity of the flavour and pairs beautifully with the oatmeal.

They’re so easy to make!

This is a fool-proof recipe. This would be a great recipe to make with kids in the kitchen. It’s quick to mix up and the icing isn’t too messy to work with. 

A simple dip and drip and then the cookies sit until the icing sets.

You know how some cookies taste amazing when they come out of the oven, but then not so much the next day?

Well, if they actually last that long, these soft and chewy oatmeal cookies taste fantastic the next day and the day after that!

I often make these cookies to share with soft oatmeal cookie lovers and I have found out that they hide them away so they do not have to share them. Yes they really are that good!

The thin layer of icing gives them a perfect sweetness that you will love in every bite.

Step-by-step instructions for making these delicious Iced Oatmeal Cookies

1. Using a food processor, process rolled oats 5 times. You want the oats to break down a little, but not completely or they will turn into oat flour. A quick burst will do it, press the button five times, then set aside.

3. Add in eggs and vanilla and beat until well combined. 

4. In a small bowl, combine all-purpose flour, cinnamon and salt.

5. Gradually add in flour and mix on low speed just until combined.

6. Add in oatmeal and blend on low speed just until combined. The mixture will be thick. Use a spatula to scrape down the sides and mix again once or twice by hand.

7. Using a heaping tablespoon, shape and roll into balls, press down to flatten slightly, then place on ungreased cookie sheet.

2.  In a large mixing bowl, or stand mixer with paddle attachment, beat butter, granulated sugar,  and brown sugar until light and fluffy. 

8. Bake in 350F oven for 10 to 12 minutes. Cookies will still be soft in the middle. 

9. Cool on baking sheet for two minutes, then transfer to wire cooling rack. (cookies must be cooled completely before icing) At least one hour.

Making the icing for oatmeal cookies

10. In a small mixing bowl, combine powdered sugar and milk. If mixture is still thick, add milk, one teaspoon at a time until the consistency is a little runny. 

11. Take cooled cookies one at a time and dip the top of the cookie into the icing. Tilt the cookie from side to side and top to bottom to even out the coating. Hold upside down until the excess icing has dripped back into the bowl. Set on wire rack. (clean up will be easier if you place a piece of plastic wrap or paper towelling underneath the wire rack). 

If you have little bubbles in the icing, use the tip of a sharp knife to gently pop them and they will disappear.

Allow the icing to set completely before stacking into a plastic storage container.

  1. These cookies are yummy but the dough is very difficult to work with. I drizzled the icing over the cookie rather than dunking it.






        1. As per the instructions below the ingredients, you would use a food processor to pulse/chop the oats a few times. It breaks them down a little. Hope that helps! Thanks 🙂 Sandra
