Preheat oven to 350°F (175°C) and line a 9x13 inch baking dish with parchment paper.
In a bowl, whisk together flour, baking soda, and salt.
In a large bowl, cream together butter, brown sugar, and granulated sugar until fluffy. Add eggs one at a time followed by vanilla; mix well.
Gradually add dry ingredients to wet ingredients until just combined. Fold in chocolate chips.
Spread half of the batter into the prepared dish. Drizzle salted caramel sauce over the top and spoon remaining batter on top.
Bake for 25-30 minutes or until golden brown. Let cool before slicing.
