Equipment

  • Baking sheet (1)
  • Parchment Paper (1 sheet)
  • Mixing Bowls (2-3, medium and large)
  • Electric Mixer (1, optional but recommended)
  • Whisk (1)
  • Cookie Scoop (1, optional)
  • Wire Rack (1, for cooling)
  • Measuring cups & spoons: 1 set each

Ingredients
  

For the Cookie Dough:

  • 1 1/2 cups 135g Rolled Oats
  • 1 1/4 cups 155g All-Purpose Flour
  • 1 tsp Baking Soda
  • 1 tsp Ground Cinnamon
  • 1/2 tsp Salt
  • 1/2 cup 115g Unsalted Butter, softened
  • 1/2 cup 100g Brown Sugar, packed
  • 1/4 cup 50g Granulated Sugar
  • 2 large Eggs
  • 2 tsp Vanilla Extract

For the Icing:

  • 1 1/2 cups 180g Powdered Sugar
  • 2-3 tbsp Milk or Heavy Cream
  • 1 tsp Vanilla Extract
  • 1 tbsp Unsalted Butter softened (optional, for richer icing)

Instructions
 

Preheat the Oven:

  • Preheat your oven to 350°F (175°C).
    Line a baking sheet with parchment paper to prevent the cookies from sticking.

Prepare the Dry Ingredients:

  • In a medium mixing bowl, whisk together the rolled oats, flour, baking soda, cinnamon, and salt. Set aside.

Cream the Butter and Sugars:

  • In a large mixing bowl, use an electric mixer to beat the softened butter, brown sugar, and granulated sugar together until light and fluffy, about 2-3 minutes.

Add the Eggs and Vanilla:

  • Add the eggs one at a time, mixing well after each addition.
    Stir in the vanilla extract and beat until the mixture is smooth.

Combine Wet and Dry Ingredients:

  • Gradually add the dry ingredients to the wet mixture, stirring until just combined.
    The dough should be thick and slightly sticky.

Scoop and Shape the Dough:

  • Use a cookie scoop or tablespoon to portion out dough onto the prepared baking sheet.
    Place the dough balls about 2 inches apart and slightly flatten them with your fingers.

Bake the Cookies:

  • Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown and the centers are set.
    Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Prepare the Icing:

  • While the cookies cool, whisk together powdered sugar, milk or cream, vanilla extract, and softened butter (if using) in a medium bowl until smooth.
    Adjust the consistency with more milk if needed.

Ice the Cookies:

  • Once the cookies are fully cooled, spread the icing generously over each one.
    Optionally, sprinkle with a light dusting of cinnamon for extra flavor.

Notes

  • Adjusting Consistency: If the icing is too thick, add a little more milk to achieve a smoother consistency. If it’s too thin, add more powdered sugar until you reach the desired thickness.
  • Oat Texture: For a chewier texture, be sure to use old-fashioned rolled oats rather than quick oats. Quick oats will result in a softer, less chewy cookie.
  • Chill the Dough (Optional): Chilling the dough for 30 minutes helps the cookies hold their shape better during baking and enhances the flavor, but it’s not necessary if you’re short on time.
  • Storage: Store leftover cookies in an airtight container at room temperature for up to 4 days. You can also freeze the cookies (without icing) for up to 3 months.
