    Recipe Ingredients Notes

    iced oatmeal cookies labelled ingredients

    Old Fashioned Oats. These are also called ‘rolled oats’. They are a flat, flakey oat perfect for cookies. Regular or gluten-free old-fashioned oats or rolled oats can be used. Do not use instant oats or quick oats for this recipe.

    All Purpose Flour. Regular or gluten-free measure-for-measure flour can be used. We use and recommend Bob’s Red Mill gluten-free 1-to-1 baking flour for gluten-free baking.

    Unsalted butter. Start with softened or room temperature butter.

    How to make Iced Oatmeal Cookies – Step-by-Step

    STEP 1. Preparation

    Preheat oven to 350 degrees F. Line a baking sheet (or sheets) with parchment paper (photo 1).

    Using a food processor, pulse oats just a few times (photos 2-3). This is just enough to break up the texture, do not pulse it into a flour consistency.

    STEP 2. Make the cookie dough

    In a medium bowl, whisk together the pulsed oats, flour, baking powder, salt, cinnamon, and nutmeg (photo 4). Set aside.

    In a large mixing bowl, using an handheld electric mixer or in the bowl of a stand mixer fitted with paddle attachment, beat the butter, brown sugar, and granulated sugar until fully combined and creamy (photo 5). Add in the eggs and vanilla; mix until combined (photo 6).

    Add in the flour mixture to the wet ingredients and mix until combined and a soft dough has formed (photo 7).

    STEP 3. Scoop, Bake and Cool

    Using a ‘medium’ cookie scoop, scoop the dough 2 tablespoons in size, and place 2 inches apart on the prepared baking sheets (photo 8). Bake for 10-12 minutes.

    Allow the cookies to cool for about 5 minutes on the cookie sheet before removing from the baking sheet (they will spread and flatten while cooling) to a wire rack (photo 9). Allow to cool completely before icing.

    iced oatmeal cookies recipe steps 9-12.

    STEP 4. Ice

    In a medium bowl, whisk together the powdered sugar (confectioners’ sugar) with 2 tablespoons of milk (photo 10). Slowly add more milk to get the desired consistency. (If it’s thick like glue you have the right consistency; it should be a thick icing).

    One by one, dip the tops of the cookies into the icing; do this very lightly (photo 11). A light dipping will allow the icing to drip into the cracks of the cookies. Another option would be to brush the icing on top with a pastry brush.

    Place on a wire cooling rack until the icing sets (photo 12).

    Variation

    Make old fashioned Oatmeal Raisin Cookies. Stir in 1 cup of raisins at the end before scooping and baking.

    Expert Tips

    These cookies spread just a little and come out of the oven super fluffy. Let them set on the cookie sheet for 5 minutes and they will finish cooking and flatten out as they cool.

    The icing is meant to mix up like a glue consistency. You want the icing to be thick so it sets and coats the cookie. A little bit of vanilla or a dash of cinnamon would be great in the icing as well.

    Use a medium (aproximately 2 tablespoons) cookie scoop. Using a cookie scoop makes cookie baking faster, less messy and ensures all the cookies are the same size (so they all bake in the same amount of time). If you don’t have one make the cookies 2 tablespoons of dough.

    Frequently Asked Questions

    Can this cookie dough be made ahead of time?

    Yes! You can make it up to 3 days before baking. Store in an airtight container in the refrigerator (or well sealed). Bring dough to room temperature before baking.

    Can I freeze these cookies?

    Yes! You can freeze them iced or before icing. Ensure they have totally cooled and if iced, that the icing is fully set. Store in an airtight freezer-safe container for up to 3 months.

    How to Store

    Once the icing has set the cookies can be stored in a covered airtight container at room temperature or chilled.

      My family and friends enjoy these cookies. I modified the recipe to be gluten-free, using Bobโ€™s Red Mill 1:1 Gluten-free Baking flour and Thrive Market organic gluten-free rolled oats. For the icing, I used Elmhurst Oatmilk instead of cow milk, and added 1 tsp of vanilla. The several batches that I have made were quickly consumed.
      Great recipe!
