Ingredients

Scale

Cookie Bars

  • 1/2 cup (113 g) unsalted butter, melted and slightly cooled
  • 1 cup (95 g) old fashioned oats
  • 1 cup plus 2 tablespoons (140 g) all-purpose flour, spooned and leveled
  • 1 teaspoon baking soda
  • 1 teaspoon cinnamon
  • 1/2 teaspoon salt
  • 1/2 cup (100 g) granulated sugar
  • 1/2 cup (100 g) light brown sugar, packed
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 1 tablespoon molasses (or honey)

Vanilla Icing

  • 1/2 cup (60 g) powdered sugar, sifted
  • 1 to 2 tablespoons whole milk
  • 1/4 teaspoon vanilla extract

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8 x 8 inch baking pan with parchment paper and set aside.
  2. Pulse Oats: Melt the butter and let it cool for about 10 minutes. Pulse the oats in a food processor until cut into smaller bits, being careful not to grind them into oat flour.
  3. Mix Dry Ingredients: In a separate bowl, whisk together the pulsed oats, all-purpose flour, baking soda, cinnamon, and salt. Set aside.
  4. Cream Butter and Sugars: Add granulated sugar and brown sugar to the melted butter. Mix on low speed or whisk for about 1 minute until the mixture resembles wet sand.
  5. Add Wet Ingredients: Add the egg, vanilla extract, and molasses (or honey) to the butter and sugar mixture. Mix until fully combined.
  6. Combine Dry and Wet: Gradually fold the dry ingredients into the wet ingredients using a spatula or wooden spoon just until incorporated. Avoid overmixing to keep the bars tender.
  7. Bake the Bars: Transfer the dough evenly into the prepared baking pan. Bake for 20 to 24 minutes until edges are set and the top has a rich, golden brown color. Avoid overbaking to prevent dryness.
  8. Cool Bars: Remove the pan from the oven and cool the bars on a wire rack for 1 to 2 hours until they are completely cool to the touch before icing.
  9. Prepare Vanilla Icing: In a medium bowl, whisk together powdered sugar, milk, and vanilla extract until smooth and thick. Adjust consistency with more powdered sugar if icing is too runny.
  10. Ice the Bars: Once the bars are cool, spoon and spread the vanilla icing over the top, allowing bits of the cookie to peek through.
  11. Set and Serve: Allow the icing to set before slicing the bars into squares and serving.

Notes

  • Do not overpulse oats; they should be chopped but not ground into flour.
  • Do not overmix the dough to keep the bars tender and chewy.
  • Watch baking time closely to avoid dry bars; edges should be set but centers slightly soft.
  • Ensure bars are completely cooled before icing to prevent melting.
  • Adjust icing thickness by adding powdered sugar or milk as needed.
