Ingredients

Scale

For the Cookie Base and Topping:

  • 1 cup unsalted butter, melted
  • 1 cup brown sugar, packed
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 1 tbsp vanilla extract
  • 2 cups all-purpose flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 2 cups rolled oats
  • 1 1/2 cups semi-sweet chocolate chips

For the Salted Caramel Filling:

  • 1 cup caramel sauce (store-bought or homemade)
  • 1/2 tsp flaky sea salt, plus more for topping


Instructions

. Prepare the Cookie Dough:

  1. Preheat your oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper.
  2. In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth.
  3. Add the eggs and vanilla extract, mixing until fully incorporated.
  4. In a separate bowl, combine the flour, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
  6. Fold in the rolled oats and chocolate chips until evenly distributed.

2. Assemble the Cookie Bars:

  1. Press half of the cookie dough mixture into the prepared pan to form an even base layer.
  2. Pour the caramel sauce over the cookie base, spreading it evenly. Sprinkle the 1/2 tsp of flaky sea salt over the caramel.
  3. Crumble the remaining cookie dough on top of the caramel layer, leaving some caramel exposed for a gooey texture.

3. Bake the Bars:

  1. Bake for 25–30 minutes, or until the top is golden brown and set. Avoid overbaking to keep the bars chewy.
  2. Remove from the oven and let the bars cool completely in the pan before cutting.

4. Serve and Enjoy:

  1. Once cooled, sprinkle extra flaky sea salt on top if desired. Slice into bars and serve.

Notes

  • For a homemade caramel sauce, combine 1 cup sugar, 6 tbsp butter, and 1/2 cup heavy cream, cooking until smooth and golden.
  • Store bars in an airtight container at room temperature for up to 3 days.
