Heat your oven to 325°F (165°C). Line a 9x13-inch baking pan with parchment paper or give it a light greasing.
02 -
Beat your softened butter with both sugars until it's light and fluffy, about 2-3 minutes. Mix in the vanilla, then gradually add flour and salt until you've got a nice crumbly dough.
03 -
Press half of your dough into the pan to make an even base. Bake it for 15 minutes until it's just starting to turn golden. Let it cool a bit.
04 -
While your base cools, stir the sea salt into your caramel sauce. Give it a taste and add more salt if you like.
05 -
Pour your salted caramel evenly over the baked crust, then crumble the remaining dough over the top to cover the caramel.

Back into the oven for 25-30 minutes until the top is lightly golden and set. Let it cool completely, or chill for 30 minutes before cutting into squares.
