What is the key to chewy iced oatmeal cookies?

If you’re aiming for chewy cookies, rather than crispy, then focus on a few factors:

  1. Make sure you have enough brown sugar in the recipe—at least as much as the white sugar. Brown sugar has more moisture than white sugar, which leads to a chewier cookie.
  2. Avoid over-mixing the batter. Add the dry ingredients to the wet ingredients, and stir until just combined. Over-mixing the batter can add too much air to the dough, resulting in tough cookies.
  3. Allow the cookies to cool completely before serving. This ensures the cookies will solidify into the perfect texture.

Protip: Avoid overbaking!

Follow the recipe instructions and pull the cookies out of the oven when they are just turning golden brown on the edges. The centers may look slightly underdone, but the cookies will firm up as they cool.

Collage of six simple steps to make iced oatmeal cookies. A text overlay reads, "How to Make Iced Oatmeal Cookies."
  1. Preheat the oven and line a baking sheet with parchment paper for easy clean-up. Then mix the dry ingredients.
  2. In a separate bowl, whisk the wet ingredients together.
  3. Combine wet and dry ingredients.
  4. Scoop the cookie dough into balls and place on a cookie sheet to bake for 11-12 minutes.
  5. While the cookies cool, make the icing. 
  6. Once the cookies are cooled, dip the tops in the icing and place the cookies on a wire rack to allow the icing to set.

Protip: Give them space!

These cookies spread out a lot in the oven, so be sure to leave plenty of space (around 2″) between the cookies. To make this full recipe, you will probably need to bake them in batches.

Should oatmeal cookies be refrigerated?

No, iced oatmeal cookies do not need to be refrigerated. Store them in an airtight container at room temperature for up to 4 days.

To freeze the leftovers, arrange them in a single layer on a baking sheet and freeze until solid. Transfer to a freezer-safe container or zip-top freezer bag and freeze for up to three months.

Protip: Don’t panic over puffy cookies!

The cookies will look puffy when they come out of the oven, but will flatten out as they cool. They are chewy and remind us a lot of the cookies on the Little Debbie oatmeal cream pies.
