Ingredients

Scale
  • 1 cup unsalted butter, softened
  • 3/4 cup brown sugar
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 3 cups rolled oats
  • 1 1/2 cups raisins

Instructions

  1. Preheat oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or grease it lightly.
  2. In a large bowl, cream softened butter with brown sugar and granulated sugar until light and fluffy.
  3. Beat in the eggs and vanilla extract until smooth.
  4. In a separate bowl, whisk together flour, baking soda, cinnamon, and salt.
  5. Gradually mix the dry ingredients into the wet ingredients until fully incorporated.
  6. Stir in the rolled oats and raisins until evenly distributed.
  7. Spread the oatmeal raisin cookie bar dough evenly in the prepared pan.
  8. Bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out clean.
  9. Cool completely before cutting into bars.

Notes

  • Soak raisins in warm water for juicier results. Drain well.
  • Do not overbake; the bars should be slightly soft in the center.
  • Lining with parchment makes cleanup easy.
  • Cool before cutting for neat squares.
  • Use old-fashioned rolled oats for best chewiness.
  • Swap raisins for chocolate chips, cranberries, or cherries.
  • Add chopped nuts for extra crunch.
  • For seasonal flair, add nutmeg or pumpkin spice.
  • For gluten-free bars, use certified gluten-free oats and a 1:1 gluten-free flour blend.
  • Store in an airtight container at room temperature for up to 5 days.
  • Freeze cooled bars individually for up to 3 months.
