Start by creaming butter and sugars together until light and fluffy. This step builds the soft texture of the bars. Then add eggs and vanilla, mixing until fully combined.
In a separate bowl, whisk flour, baking soda, and salt together. Gradually add it into the wet mixture until a thick cookie dough forms.
Fold in chocolate chips evenly so every bite has chocolate. Spread half the dough into a lined baking pan as the base layer.
Pour caramel sauce evenly over the cookie base, making sure it reaches the edges. Sprinkle a little sea salt for that sweet-salty contrast.
Add the remaining cookie dough on top and gently spread it. Bake until golden brown and slightly firm in the center.
Let the bars cool completely before cutting to avoid a messy texture. This helps the caramel set perfectly inside each bite.
