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 and ensure even baking.
  2. Pulse oats: Place the rolled oats in a food processor and pulse 4–5 times until they are coarsely ground for better texture integration into the cookie dough.
  3. Mix dry ingredients: In a large bowl, whisk together the ground oats, all-purpose flour, baking soda, cinnamon, nutmeg, and salt until evenly combined.
  4. Combine wet ingredients: In a separate bowl, whisk the melted, cooled unsalted butter with brown sugar and granulated sugar. Stir in the beaten egg and vanilla extract thoroughly.
  5. Form dough: Gradually add the dry ingredients to the wet ingredients, mixing gently with a wooden spoon until just combined to avoid overworking the dough and toughening the cookies.
  6. Optional chilling: Chill the dough for 20 minutes if you prefer thicker cookies, which helps the dough firm up and prevents excessive spreading.
  7. Shape cookies: Scoop 1 tablespoon of dough for each cookie, roll into balls, and place them 2 inches apart on the prepared baking sheets. For flatter cookies, gently press the balls down with your fingers before baking.
  8. Bake cookies: Bake in the preheated oven for 12 minutes or until the edges are set and the tops are lightly golden, indicating the cookie is perfectly baked.
  9. Cool cookies: Transfer the cookies to a wire rack and allow them to cool completely before glazing to avoid melting the icing.
  10. Prepare glaze and ice: Mix powdered sugar, milk, and optional light corn syrup and vanilla or maple extract until smooth. Dip the tops of the cooled cookies into the glaze, then place them on a parchment-lined baking sheet with a cooling rack on top. Let the glaze set fully before stacking or serving.

Notes

  • Coarsely pulsing oats enhances texture—avoid over-processing to maintain chewiness.
  • Chilling the dough is optional but recommended for thicker cookies and better flavor development.
  • Light corn syrup in glaze creates a shiny finish but can be omitted without affecting taste.
  • Use parchment paper or silicone mats to prevent sticking and facilitate easy cleanup.
  • Store glazed cookies in an airtight container at room temperature to keep them fresh up to 3 days.
  • For a maple twist, replace vanilla extract in the glaze with maple extract.
