Description

Delicious iced oatmeal cookies with a soft, chewy texture and a sweet vanilla glaze. These cookies combine the wholesome goodness of oats with warm spices and a shiny glazed finish for the perfect treat.


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
  • 2-3 tablespoons milk
  • 1 teaspoon light corn syrup (optional, for a shiny sheen)
  • 1/4 teaspoon vanilla or maple extract (optional)

Instructions

  1. Preheat and prepare baking sheets: Preheat your oven to 350°F. Line baking sheets with parchment paper to prevent sticking and for easy cleanup.
  2. Pulse oats: Place the rolled oats in a food processor and pulse 4–5 times until they are coarsely ground but not completely fine.
  3. Mix dry ingredients: In a large bowl, whisk together the pulsed oats, all-purpose flour, baking soda, cinnamon, nutmeg, and salt until evenly combined.
  4. Mix wet ingredients: In another bowl, whisk the melted and cooled butter with the brown sugar and granulated sugar until smooth. Stir in the beaten egg and vanilla extract until fully incorporated.
  5. Combine wet and dry: Add the dry ingredients to the wet ingredients and mix gently with a wooden spoon until just combined. Avoid overmixing to keep cookies tender.
  6. Chill dough (optional): For thicker cookies, refrigerate the dough for 15–20 minutes. This step can be skipped if a thinner cookie is desired.
  7. Shape cookies: Scoop about 1 tablespoon of dough per cookie and roll into balls. Place them 2 inches apart on the prepared baking sheets. Press the balls gently with your fingers for flatter cookies.
  8. Bake: Bake the cookies in the preheated oven for 12 minutes, or until the edges are set and both tops and edges are slightly golden.
  9. Cool: Transfer the cookies to a wire rack and let them cool completely before glazing.
  10. Prepare glaze: In a small bowl, mix the powdered sugar with 3 tablespoons of milk. Add 1 teaspoon of light corn syrup and ¼ teaspoon vanilla or maple extract if using, stirring until smooth and glossy.
  11. Glaze cookies: Dip the tops of the cooled cookies into the glaze, then place them back on a parchment-lined baking sheet with a cooling rack on top to let excess glaze drip and set.
  12. Set glaze: Allow the glaze to fully set before stacking or serving the cookies.

Notes

  • Chilling the dough helps prevent spreading and results in thicker cookies.
  • Use light corn syrup in the glaze for a shinier finish, but it is optional.
  • Adjust glaze thickness by adding more powdered sugar to thicken or more milk to thin.
  • Store cookies in an airtight container at room temperature for up to 5 days.
  • For gluten-free version, substitute the all-purpose flour with gluten-free flour blend.
