Ingredients
  

  • cups old-fashioned rolled oats
  • cups all-purpose flour
  • 1 cup packed brown sugar
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ¾ cup unsalted butter melted
  • 2 cups fresh or frozen cranberries if frozen, do not thaw
  • ½ cup granulated sugar
  • 1 tablespoon orange zest from about 1 medium orange
  • 2 tablespoons orange juice
  • 1 tablespoon cornstarch
  • ½ teaspoon vanilla extract
  • ½ cup chopped walnuts or pecans optional

Instructions
 

  • Preheat your oven to 350°F (175°C) and line a 9×9 inch baking pan with parchment paper, leaving overhang on the sides for easy removal.
  • Prepare the cranberry filling by combining cranberries, granulated sugar, orange zest, orange juice, and cornstarch in a medium saucepan. Cook over medium heat for 5-7 minutes, stirring frequently, until cranberries burst and mixture thickens. Remove from heat, stir in vanilla extract, and set aside to cool slightly.
  • Make the oatmeal mixture by combining oats, flour, brown sugar, baking soda, and salt in a large bowl. Pour in the melted butter and stir until everything is evenly moistened and resembles coarse crumbs.
  • Press two-thirds of the oat mixture firmly into the bottom of your prepared pan, creating an even base layer.
  • Spread the cranberry filling evenly over the base layer, leaving a small border (about ¼ inch) around the edges.
  • Add nuts to the remaining oat mixture if using, then sprinkle this crumble topping evenly over the cranberry layer.
  • Bake for 25-30 minutes until the top is golden brown and the edges are slightly darker. Look for the cranberry filling to be bubbling slightly at the edges—this indicates it’s done.
  • Cool completely in the pan on a wire rack for at least 2 hours before lifting out using the parchment overhang and cutting into squares.

Notes

  • These bars can be stored in an airtight container at room temperature for 3 days or refrigerated for up to a week.
  • For cleaner cuts, refrigerate the bars for an hour after they’ve cooled to room temperature.
  • The cranberry filling can be made a day ahead and refrigerated to save time.
  • Lining the pan with parchment paper is crucial for easy removal—don’t skip this step!
  • The orange zest adds significant flavor complexity—use a microplane for best results.
