Description

An elegant take on oatmeal raisin cookies, these bar cookies feature browned butter, toasted oats, and plump raisins, delivering a chewy texture with a sophisticated flavor.


Ingredients

Scale
  • 1 cup (226 g) unsalted butter, browned and cooled slightly
  • 1 cup (200 g) light brown sugar, packed
  • 1/2 cup (100 g) granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 1/2 cups (190 g) all-purpose flour, spooned and leveled
  • 1 teaspoon baking soda
  • 1/2 teaspoon fine sea salt
  • 1 1/2 teaspoons ground cinnamon
  • Zest of 1 orange, finely grated
  • 2 1/2 cups (225 g) old-fashioned rolled oats, lightly toasted
  • 1 1/2 cups (225 g) raisins, warmed and plumped
  • Flaky sea salt for finishing
  • 1/3 cup chopped walnuts or pecans, toasted

Instructions

  1. Preheat the oven to 350°F (175°C). Line a 9×13 inch pan with parchment, leaving an overhang to lift the bars.
  2. Brown the butter: Melt butter in a light-colored skillet over medium heat, swirling until solids turn golden-brown and aroma becomes nutty. Remove from heat and let cool until warm to the touch.
  3. Whisk sugars into the warm browned butter until slightly glossy. Add eggs one at a time, then stir in vanilla and orange zest until the mixture glows and holds a ribbon.
  4. In a bowl, combine flour, baking soda, salt, and cinnamon. Fold the dry mix into the butter-sugar mixture until just combined; avoid overmixing to keep tender texture.
  5. Toast the oats in a dry skillet over medium-low until fragrant and a touch darker, about 4–5 minutes. Cool, then fold oats and plumped raisins into the batter along with toasted nuts if using.
  6. Press the mixture evenly into the prepared pan, smoothing the top with an offset spatula. Sprinkle flaky sea salt lightly.
  7. Bake for 22–28 minutes, until the edges are golden-brown and a toothpick shows a few moist crumbs.
  8. Cool completely in the pan on a rack before lifting out and slicing into bars.

Notes

Chill briefly before slicing for neat, uniform bars. Store bars in an airtight container for optimal freshness.
