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

Instructions

  1. Preheat Oven 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 1 cup rolled oats in a food processor and pulse 4 to 5 times until they are coarsely ground but still have some texture.
  3. Combine Dry Ingredients: In a large bowl, whisk together the pulsed oats, 1 cup all-purpose flour, ½ teaspoon baking soda, ½ teaspoon cinnamon, ¼ teaspoon nutmeg, and ½ teaspoon salt until evenly mixed.
  4. Mix Wet Ingredients: In a separate bowl, whisk the ½ cup melted and cooled unsalted butter with ½ cup brown sugar and ¼ cup granulated sugar until smooth. Stir in 1 beaten large egg and 1 teaspoon vanilla extract until combined.
  5. Combine Dough: Add the dry ingredients to the wet mixture and gently stir with a wooden spoon until just combined—do not overmix to keep cookies tender.
  6. Optional Chill: For thicker cookies, chill the dough in the refrigerator for 15 to 20 minutes.
  7. Shape Cookies: Scoop 1 tablespoon of dough per cookie. Roll each scoop into a ball and place them about 2 inches apart on the prepared baking sheets. For flatter cookies, gently press the balls down with your fingers before baking.
  8. Bake: Bake the cookies for 12 minutes until the edges are set and both tops and edges have a slight golden color.
  9. Cool: Transfer cookies to a wire rack to cool completely before glazing.
  10. Prepare Glaze and Ice Cookies: In a bowl, mix 1 cup powdered sugar with 2 to 3 tablespoons milk until smooth. Optionally add 1 teaspoon light corn syrup and ¼ teaspoon vanilla or maple extract for a shiny and flavored glaze. Dip the tops of cooled cookies in the glaze, then place on a parchment-lined baking sheet with a cooling rack on top. Allow the glaze to set completely before stacking or serving.

Notes

  • Lightly pulsing oats gives a better texture than fully ground oat flour for these cookies.
  • Chilling the dough helps control spreading, resulting in thicker cookies.
  • Pressing dough balls gently before baking creates a flatter cookie if preferred.
  • The glaze can be flavored with vanilla or maple extract to complement the spices in the dough.
  • Use parchment paper to avoid sticking and for easier cleanup.
  • Store glazed cookies in an airtight container at room temperature for up to 3 days for best freshness.
