How to Make
Step 1
Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Line a cookie pan with parchment paper.
Step 2
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Step 3
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
Step 4
In a separate bowl, whisk together the flour, baking soda, ground cinnamon, and salt. Gradually add this dry mixture to the butter-sugar mixture, mixing until just combined.
Step 5
Stir in the oats until they are evenly distributed throughout the dough.
Step 6
Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart. Flatten each cookie slightly with the back of a spoon or your fingertips.
Step 7
Bake in the preheated oven for 10 to 12 minutes, or until the edges are golden brown. The centers may still be slightly soft.
Step 8
Remove the cookies from the oven and allow them to cool on the baking sheets for 5 minutes. Next, transfer them to a wire rack to cool completely.
Step 9
While the cookies are cooling, make the icing. In a medium bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth. Add more milk if needed to achieve a smooth consistency.
Step 10
Once the cookies have cooled, drizzle the icing over the top of each cookie using a spoon or a piping bag. Allow the icing to set before serving.
Step 11
Serve these delicious homemade iced oatmeal cookies!
Expert Tips & Tricks
Use old-fashioned rolled oats. Old-fashioned rolled oats provide the best texture for these cookies. Avoid using quick oats or instant oats, as they may result in a mushy texture.
Measure the ingredients accurately. For consistent results, ensure precise measurements of the ingredients.
Cream the butter and sugars thoroughly. Cream the softened butter, granulated sugar, and brown sugar together until light and fluffy. This process will give you a lovely light-iced oatmeal cookie. Use a hand mixer or stand mixer for this.
Adjust the icing consistency. When preparing the icing, adjust its consistency by adding more powdered sugar for thicker icing or more milk.
Let the cookies cool completely before icing. Ensure that the cookies are completely cooled before applying the icing.
Store properly. Once the icing has dried, store the cookies in an airtight container at room temperature. Layer the cookies between parchment or wax paper to prevent sticking and maintain their texture.
