Preheat your oven to 350°F (175°C) and prepare a 9x13 inch baking dish by lightly greasing or lining with parchment paper.

In a large mixing bowl, cream together the softened unsalted butter, brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes.

Add the eggs one at a time, beating well after each addition. Pour in the vanilla extract and mix until combined.

In a separate bowl, whisk together the all-purpose flour, baking soda, and salt until evenly mixed.

Gradually add the dry mixture to the wet ingredients, stirring gently until just combined.

Fold in the semi-sweet chocolate chips using a spatula.

Spread the cookie dough evenly in the prepared baking dish.

Bake for 25-30 minutes, or until edges are golden brown and a toothpick inserted in the center comes out clean.

While the bars are baking, melt the salted caramel sauce in a microwave-safe bowl.

Once the bars are out of the oven and slightly cooled (about 10-15 minutes), drizzle the warm caramel sauce over the top.

Allow the cookie bars to cool completely before slicing into squares or rectangles.
