Description

Delight in these refreshing Iced Lemon Oatmeal Cookies, featuring zesty lemon sugar-infused oats and a smooth lemon glaze. These soft and slightly chewy cookies combine bright citrus flavors with wholesome oats, perfect for a sunny afternoon treat or a lovely dessert.


Ingredients

Cookie Dough

  • 1 1/3 cup granulated sugar
  • Zest of one lemon
  • 1 cup salted butter, softened
  • 1/4 teaspoon lemon extract (optional)
  • 1 cup all-purpose flour
  • 3/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 1/2 cups old fashioned oats

Lemon Icing

  • 2 cups powdered sugar
  • 1-2 tablespoons fresh lemon juice (more as needed)


Instructions

  1. Preheat Oven and Prepare Baking Sheet: Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius) and line a baking sheet with parchment paper to prevent sticking and ensure even baking.
  2. Make Lemon Sugar: In a small bowl, combine the granulated sugar and lemon zest. Rub the zest into the sugar with your fingers to release the lemon oils, enhancing the lemon flavor intensively.
  3. Cream Butter and Lemon Sugar: Using an electric stand mixer, cream together the softened butter and lemon-infused sugar until light and fluffy. If desired, add 1/4 teaspoon lemon extract to boost the lemon aroma and flavor.
  4. Add Dry Ingredients: Gradually mix in the all-purpose flour, baking soda, salt, and oats until a cohesive dough forms. The oats provide texture and wholesome flavor.
  5. Scoop and Bake Cookies: Using a tablespoon, scoop dough balls onto the prepared baking sheet, spacing about 12 cookies per sheet. Bake for 12-14 minutes, or until the edges turn golden brown. Allow cookies to cool on the baking sheet for 3 minutes before transferring to a wire rack to cool completely.
  6. Prepare Lemon Icing: In a shallow bowl, whisk together the powdered sugar and fresh lemon juice starting with 1 tablespoon. Add more juice gradually until the consistency resembles white glue — thick but spreadable. Avoid making icing too runny.
  7. Ice the Cookies: Gently dab the top of each cooled cookie into the lemon icing, ensuring a thin layer of glaze. Allow the icing to set completely before stacking or serving.

Notes

  • For a stronger lemon aroma, you may add the 1/4 teaspoon lemon extract, but it is optional.
  • The icing consistency is critical; start thick and add juice slowly to avoid runny glaze.
  • Cooling the cookies slightly on the baking sheet prevents breakage when transferring to the rack.
  • Store iced cookies in an airtight container at room temperature for up to 3 days.
  • Old fashioned oats work best to provide texture; quick oats can be substituted but will yield a softer bite.
