Ingredients
  

Cookie Base
  • 1 cup unsalted butter softened to room temperature
  • 1 cup packed light brown sugar
  • 1/2 cup granulated sugar
  • 2 large eggs room temperature
  • 1 tsp vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1 tsp baking soda
  • 1 tsp ground cinnamon
  • 1/2 tsp salt
  • 3 cups old-fashioned rolled oats
  • 1 cup raisins
Icing
  • 1 cup powdered sugar sifted
  • 2 tbsp milk or more for desired consistency
  • 1/2 tsp vanilla extract

Method
 

  1. Preheat your oven to 350°F (175°C). Line a 9x13-inch baking sheet with parchment paper, leaving overhang on two sides for easy removal.
  2. In a large bowl, beat the softened butter, brown sugar, and granulated sugar together with an electric mixer on medium speed until light and fluffy, about 2-3 minutes.
  3. Beat in the eggs one at a time, then add the vanilla extract, mixing until well combined.
  4. In a separate medium bowl, whisk together the flour, baking soda, cinnamon, and salt. Gradually add the dry mixture to the wet mixture, mixing on low speed until just combined.
  5. Using a spatula, fold in the rolled oats and raisins until evenly distributed throughout the dough.
  6. Transfer the dough to the prepared baking sheet and press it evenly into a flat layer using your hands or a spatula. The dough should be about 1/2-inch thick.
  7. Bake for 25-30 minutes, or until the edges are golden brown and the center is set. A toothpick inserted into the center should come out clean or with a few moist crumbs.
  8. Allow the bars to cool completely in the pan on a wire rack, about 1 hour. This is essential for clean slicing.
  9. In a small bowl, whisk together the sifted powdered sugar, milk, and vanilla extract until smooth. Adjust milk to reach a drizzling consistency.
  10. Drizzle the icing over the cooled bars using a spoon or piping bag. Let the icing set for 10 minutes, then lift the bars out using the parchment overhang and cut into squares.
