Ingredients

Units Scale

Cookie Bars

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

Vanilla Icing

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

Instructions

  1. Preheat and Prepare: Preheat your oven to 350°F. Line an 8 x 8 inch baking pan with parchment paper and set aside.
  2. Process Oats: Melt the butter and let it cool for about 10 minutes. Meanwhile, pulse the oats in a food processor just until they are cut into smaller bits, avoiding turning them into oat flour.
  3. Mix Dry Ingredients: In a separate bowl, whisk together the pulsed oats, flour, baking soda, cinnamon, and salt. Set aside.
  4. Combine Butter and Sugars: To the cooled melted butter, add both sugars and mix on low speed or whisk for one minute until the mixture resembles wet sand.
  5. Add Wet Ingredients: Add the egg, vanilla extract, and molasses to the butter and sugar mixture. Mix well to combine.
  6. Fold in Dry Ingredients: Add the dry mixture to the wet ingredients and fold gently with a spatula or wooden spoon just until incorporated. Avoid overmixing.
  7. Bake: Transfer the dough evenly into the prepared baking pan and bake for 24 minutes, or until edges are set and the top is golden brown.
  8. Cool Bars: Remove from oven and let the bars cool completely in the pan on a wire rack for 1 to 2 hours before icing.
  9. Prepare Icing: In a medium bowl, whisk together powdered sugar, milk, and vanilla extract until thick but smooth. Adjust thickness by adding more powdered sugar if needed.
  10. Ice the Bars: Once bars are cool, spread the icing evenly over the top, leaving some cookie surface visible.
  11. Set and Serve: Allow the icing to set before slicing into 16 squares and serving.

Notes

  • Store bars tightly covered at room temperature for up to 4 days to maintain freshness.
  • For longer storage, freeze the bars without icing after they are completely cooled. Freeze for up to 3 months and defrost at room temperature before adding the icing.
  • To keep the icing from being too runny, add powdered sugar gradually.
