Delicious and chewy iced oatmeal cookies with a subtle spice blend, topped with a sweet vanilla glaze. Perfect for a cozy snack or dessert, these cookies combine the heartiness of oats with warm cinnamon and nutmeg, finished with a shiny, smooth icing.


Ingredients

Units Scale

Cookie Dough:

  • 1 cup rolled oats lightly pulsed in a food processor
  • 1 cup all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon cinnamon
  • 1/4 teaspoon nutmeg
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter, melted and cooled
  • 1/2 cup brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg, beaten
  • 1 teaspoon vanilla extract

Glaze:

  • 1 cup powdered sugar
  • 3 tablespoons milk
  • 1 teaspoon light corn syrup (optional, for a shiny sheen)
  • 1/4 teaspoon vanilla or maple extract (optional)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F and line baking sheets with parchment paper to prevent sticking.
  2. Pulse Oats: Lightly pulse the rolled oats 4–5 times in a food processor until they are coarsely ground but not a fine flour.
  3. Combine Dry Ingredients: In a bowl, whisk together the pulsed oats, all-purpose flour, baking soda, cinnamon, nutmeg, and salt until evenly distributed.
  4. Mix Wet Ingredients: In another bowl, whisk the melted and cooled butter with brown sugar and granulated sugar. Then stir in the beaten egg and vanilla extract until smooth.
  5. Combine Dough: Gradually stir the dry ingredients into the wet mixture just until combined using a wooden spoon. Avoid overmixing for tender cookies.
  6. Chill Dough (Optional): For thicker cookies, chill the dough for 15–20 minutes before baking.
  7. Form Cookies: Scoop 1 tablespoon of dough per cookie and roll into balls. Place them 2 inches apart on the prepared baking sheets. For flatter cookies, gently press down the balls with your fingers.
  8. Bake Cookies: Bake in the preheated oven for 12 minutes or until the edges are set and the tops and edges are lightly golden.
  9. Cool Cookies: Transfer the baked cookies to a wire rack to cool completely before applying glaze.
  10. Prepare Glaze: Mix powdered sugar with 3 tablespoons milk until smooth. Add corn syrup and vanilla or maple extract if using, for shine and flavor.
  11. Ice Cookies: Dip the tops of the cooled cookies into the glaze, then place them on a baking sheet lined with parchment and a cooling rack set on top to allow the icing to set completely before stacking and serving.

Notes

  • Lightly pulsing oats gives the cookies a nice texture without making them too fine.
  • Chilling the dough helps prevent spreading for thicker, chewier cookies.
  • If you prefer a stronger spice flavor, increase cinnamon to 1 teaspoon.
  • Use light corn syrup in the glaze for a shiny finish, but you can omit it if unavailable.
  • Store cookies in an airtight container to maintain freshness for up to 5 days.
