01 - Preheat oven to 350°F (175°C). In a large mixing bowl, whisk together rolled oats, all-purpose flour, packed brown sugar, and fresh orange zest.
02 - Pour in melted unsalted butter and honey. Stir thoroughly until all dry ingredients are moistened and mixture is cohesive.
03 - Gently fold in fresh cranberries. Press the oat mixture evenly into a parchment-lined 8x8-inch baking pan, ensuring a uniform thickness.
04 - Bake on the center rack for 25 to 30 minutes, or until the top is golden and edges are set.
05 - Allow bars to cool completely in the pan before lifting out and cutting into squares.
