Make the caramel first so it has time to cool. Place a medium saucepan over medium heat and gradually add 1 cup of sugar, 1/4 cup at a time, stirring occasionally. Allow the sugar to melt and deepen in color before adding the next portion. Once fully melted and amber-colored, turn off the heat and mix in 6 Tbsp butter, 1/2 cup heavy cream, 1 tsp vanilla extract, and 1/2 tsp salt. Transfer to a container, cool in the fridge, and whip with a mixer for 1-2 minutes until lighter in color and thicker.

Pour the batter into the prepared pan and smooth it out. Bake at 162 C (325 F) for 40-45 minutes, until a toothpick inserted comes out with a few moist crumbs. Cool completely on a wire rack. For faster cooling, place the pan in the freezer for 30 minutes.

Spread the whipped caramel onto the cooled brownies, top with flakey sea salt, then chill. Use a sharp, warm knife to cut into slices, cleaning the blade after each cut.
