People love iced oatmeal cookie bars not just for their irresistible taste, but also for their convenience.

Ingredients:
- 1 cup unsalted butter, softened
- 1 cup brown sugar, packed
- 1/2 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon ground cinnamon
- 1/2 teaspoon salt
- 3 cups old-fashioned rolled oats
- 1 cup raisins or chocolate chips (optional)
- 1 cup powdered sugar (for icing)
- 2 tablespoons milk (for icing)
- 1/2 teaspoon vanilla extract (for icing)
Preparing the Batter
- Start by preheating your oven to 350°F (175°C). This ensures that your cookie bars bake evenly and come out perfectly golden.
- In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar. I like to use an electric mixer for this step, but you can also do it by hand with a wooden spoon. Mix until the mixture is light and fluffy, which usually takes about 2-3 minutes.
- Add the eggs, one at a time, mixing well after each addition. Then, stir in the vanilla extract. This will add a lovely flavor to your cookie bars.
- In a separate bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, and salt. This helps to evenly distribute the leavening agent and spices throughout the flour.
- Gradually add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix, as this can make your cookie bars tough.
- Now, fold in the rolled oats. If youre using raisins or chocolate chips, this is the time to add them as well. I love the texture that the oats provide, and the optional add-ins can really elevate the flavor!
Cooking Process
- Prepare a 9×13 inch baking pan by greasing it lightly with butter or lining it with parchment paper. This will make it easier to remove the bars once they are baked.
- Spread the cookie batter evenly into the prepared baking pan. I like to use a spatula to smooth the top, ensuring that its evenly distributed.
- Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out clean. Keep an eye on them towards the end of the baking time to prevent overbaking.
- Once baked, remove the pan from the oven and let it cool in the pan for about 10-15 minutes. Then, transfer the cookie bars to a wire rack to cool completely. This step is crucial for achieving the perfect texture.
Preparing the Icing
- While the cookie bars are cooling, lets prepare the icing. In a medium bowl, combine the powdered sugar, milk, and vanilla extract. I like to start with 1 tablespoon of milk and add more if needed to reach the desired consistency.
- Whisk the ingredients together until smooth. The icing should be thick but pourable. If its too thick, add a little more milk, and if its too thin, add a bit more powdered sugar.
Assembling the Cookie Bars
- Once the cookie bars are completely cooled, its time to ice them! Pour the icing over the top of the bars, using a spatula to spread it evenly. I love to let the icing drip over the edges for a beautiful presentation.
- Allow the icing to set for about 30 minutes before cutting the bars into squares. This will help the icing firm up a bit, making it easier to slice.
- Using a sharp knife, cut the bars into squares or rectangles, depending on your preference. I usually aim for about 24 bars, but you can make them larger or smaller based on your liking.
- Serve the iced oatmeal cookie bars on a platter or store them in an airtight container. They can be kept at room temperature for a few days, or
