Welcome to My Kitchen! I am sharing my favorite recipe for soft and chewy iced oatmeal cookies. These old-fashioned cookies have warm spices and a sweet vanilla glaze, making them a perfect comfort food baking project for any day or holiday.

Ingredients

Scale
  • 1 cup unsalted butter, softened
  • 1 cup packed light brown sugar
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 1/4 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/2 teaspoon salt
  • 3 cups old-fashioned rolled oats
  • For the Glaze: 2 cups powdered sugar
  • 4 tablespoons milk
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
  2. In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. This takes about 3 minutes with an electric mixer.
  3. Beat in the eggs one at a time, then mix in the vanilla extract.
  4. In a separate medium bowl, whisk together the flour, baking soda, cinnamon, nutmeg, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix.
  6. Stir in the rolled oats by hand until evenly distributed throughout the dough.
  7. Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart. You can gently flatten them slightly if you prefer a less domed cookie.
  8. Bake for 10 to 12 minutes, or until the edges are set and lightly golden. The centers should still look soft.
  9. Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
  10. While the cookies cool, prepare the glaze: Whisk together the powdered sugar, milk, and vanilla extract in a small bowl until smooth. Add more milk, one teaspoon at a time, if the glaze is too thick.
  11. Once the cookies are completely cool, drizzle or spread the vanilla glaze over the top of each cookie. Let the glaze set before serving or storing.

Notes

  • For a bakery style cookie, chill the dough for 30 minutes before scooping. This helps prevent spreading.
  • If you want a brown butter cookie flavor, brown your butter before using it in the recipe. Let it cool slightly before creaming it with the sugars.
  • This recipe makes a great lunchbox treat or dessert for a crowd.
