Set your oven to 325°F (165°C). Use parchment paper or a little grease to prep a 9x13-inch pan.
02 -
Cream the butter and both types of sugar until soft and fluffy, which takes around 2 to 3 minutes. Blend in the vanilla, then slowly mix in the flour and salt. The dough will have a crumbly texture.
03 -
Put half the dough into the pan and press it down evenly. Bake it for 15 minutes or until the edges start to lightly brown. Let it cool off for a moment.
04 -
As the crust cools, mix the salt into the caramel sauce to taste. Check it and add extra salt if you want a little more kick.
05 -
Spread the caramel evenly on top of the baked crust. Then crumble the rest of the dough across the caramel layer to cover it up.

Pop it back in the oven and bake for another 25–30 minutes. The crust should set and turn a light golden color. Cool it down completely (or chill it for 30 minutes) before cutting into squares.
