Preheat your oven to 350°F (175°C) and line a 9x13-inch baking dish with parchment paper.

In a medium mixing bowl, whisk together the flour, baking soda, and salt until well combined.

In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. Add eggs one at a time followed by vanilla extract.

Gradually add dry ingredients to wet mixture, stirring gently. Fold in the chocolate chips.

Spoon half the dough into the prepared baking dish, drizzle the caramel sauce evenly, and spread the remaining dough on top.

Bake for 25-30 minutes until golden brown. Check with a toothpick for moist crumbs.

Let cool completely, sprinkle with sea salt if desired, lift out using parchment, and cut into squares.
