Ingredients

Scale
  • 1 cup unsalted butter, softened
  • 1 cup packed light brown sugar
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 2 teaspoons pure vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 3 cups old-fashioned rolled oats
  • 1 1/2 cups raisins
  • 2 tablespoons milk

Instructions

  • Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper.
  • In a large bowl, beat the softened butter, brown sugar, and granulated sugar until light and fluffy.
  • Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.
  • In a separate bowl, whisk together the flour, baking soda, cinnamon, and salt.
  • Gradually add the dry ingredients to the wet mixture and stir until just combined.
  • Fold in the old-fashioned rolled oats, raisins, and milk. Mix until evenly incorporated.
  • Press the dough evenly into the prepared baking pan and smooth the top.
  • Bake for 22 to 28 minutes, until the edges are lightly golden and the center is just set.
  • Cool completely in the pan before slicing into bars.

Notes

  • For the chewiest texture, do not overbake.
  • Old-fashioned rolled oats give the best texture in this recipe.
  • If your raisins are dry, soak them in warm water for 10 minutes, then drain and pat dry before using.
  • Store the bars in an airtight container at room temperature for up to 4 days.
  • These bars freeze well for up to 2 months.
