Ingredients

Units Scale

Cookie

  • 1 cup old fashioned rolled oats
  • 1 cup all-purpose flour plus 2 tbsp
  • 1 tsp cornstarch
  • 1/2 tbsp baking powder
  • 1/4 tsp baking soda
  • 1/4 tsp salt
  • 1 1/4 tsp cinnamon
  • 1/4 tsp ground nutmeg
  • 8 tbsp (1 stick) butter, softened
  • 1/2 cup packed brown sugar
  • 1/4 cup sugar
  • 1 egg
  • 1 tsp vanilla extract

Glaze

  • 1 cup powdered sugar
  • 1/4 tsp vanilla extract
  • 1 1/2 tbsp milk

Instructions

  1. Preheat and prepare baking sheets: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper or silicone baking mats to prevent sticking.
  2. Process oats: Place the rolled oats in a food processor and pulse 10-12 times until you achieve a mix of ground and whole oats for texture.
  3. Combine dry ingredients: In a medium bowl, whisk together the processed oats, flour, cornstarch, baking powder, baking soda, salt, cinnamon, and nutmeg until well mixed.
  4. Cream butter and sugars: Using a stand mixer or hand mixer, cream the softened butter, brown sugar, white sugar, and vanilla extract on high speed for about 2 minutes until the mixture is light and fluffy.
  5. Add egg: Lower the mixer speed to low and incorporate the egg fully into the butter and sugar mixture.
  6. Mix dry ingredients into wet: Gradually add the dry ingredients to the wet mixture, mixing just until combined to avoid overworking the dough.
  7. Chill dough: Refrigerate the cookie dough for 20-30 minutes to firm up and make it easier to handle.
  8. Scoop and bake: Using a standard cookie scoop, portion balls of dough onto the prepared baking sheets and bake in the preheated oven for 10-14 minutes. For crispier cookies, bake for the full 14 minutes.
  9. Cool cookies: Remove the cookies from the oven and let them cool on the baking sheet for 3 minutes before transferring to a wire rack to cool completely.
  10. Prepare glaze: In a small bowl, whisk together the powdered sugar, vanilla extract, and milk until smooth.
  11. Ice cookies: Once cookies are fully cool, dip the tops into the glaze and swirl to remove excess icing.
  12. Set glaze: Allow the glazed cookies to sit for 30 minutes so the icing can set properly before serving.

Notes

  • Refrigerating the dough makes it easier to handle and improves the texture of the cookies.
  • Pulse the oats just enough to keep some texture; fully grinding the oats will change the cookie’s traditional chewy texture.
  • For softer cookies, reduce the baking time slightly.
  • The glaze can be customized by adding a pinch of cinnamon or lemon zest for extra flavor.
  • Store iced cookies in an airtight container to maintain freshness.
