Step-by-Step Directions for Brown Butter Oatmeal Raisin Cookie Bars
Start by melting 1 cup of unsalted butter in a saucepan over medium heat. Watch closely as it turns golden brown, releasing a delightful nutty aroma. Remove it from the heat and allow it to cool for about 15 minutes.
Preheat your oven to 350°F (175°C). Prepare a 9×13-inch baking pan by greasing it or lining it with parchment paper, ensuring that your bars won’t stick.
In a large mixing bowl, whisk together the cooled brown butter, brown sugar, and granulated sugar until the mixture is smooth and well combined. Add the eggs and vanilla extract, mixing thoroughly.
In a separate bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, and salt. Gradually incorporate this dry mixture into the wet ingredients, mixing until just combined.
Gently fold in the rolled oats and raisins, making sure they are evenly distributed throughout the batter.
Spread the batter evenly in the prepared baking pan. Bake in the preheated oven for 22–26 minutes, or until the edges are golden and a toothpick inserted in the center comes out clean. Let the bars cool completely in the pan before frosting.
To make the frosting, brown 1/2 cup of unsalted butter as before. Transfer the browned butter to a mixing bowl, and add in the powdered sugar, milk, vanilla extract, and a pinch of salt. Beat the mixture until it becomes smooth and fluffy, adjusting the milk if necessary to reach your desired consistency.
Once the cookie bars have cooled, spread the frosting over the top using a spatula. Use the back of a spoon to create swirls, adding a few extra raisins on top for decoration if desired.
Cut the bars into squares and serve immediately, or store them in an airtight container for future enjoyment!

Feel free to experiment with different sugars, like coconut sugar or agave nectar, but this may alter the flavor and texture slightly.
