Start this ahead to give the caramel a chance to set. Heat a medium-sized pot over medium-high flame. Slowly sprinkle in some sugar, roughly 1/4 cup at a time, using a rubber spatula to stir occasionally. Add the next batch only once the previous one has mostly dissolved. Watch as the color deepens into a toasty golden hue while it melts.

After all the sugar's melted into a glossy amber syrup, switch off the heat. Stir in butter bit by bit (start with about 2 Tbsp portions) until it's blended in. Then, mix in the cream, vanilla, and salt slowly. While it'll seem runny now, letting it chill will firm it up. Place it in a container and refrigerate to cool faster.

Once the caramel's at room temp, pull out your mixer. Beat it on a medium-high speed for just a minute or so, until it noticeably thickens and lightens in color. Set it aside as you'll need it later for topping.

Warm your oven up to 162°C (325°F). Prep an 8-inch square metal tin with parchment so the edges hang over for easy lifting, then lightly spritz it with cooking spray. No square pan? A round 8-9 inch metal one works too.

In a medium mixing bowl, toss in powdered sugar, granulated sugar, cocoa, flour, chopped chocolate chips, and salt. Stir it all up until it looks evenly mixed.

Put eggs, oil, melted butter, vanilla, and water in a big bowl. Whisk them until you’re left with a smooth mixture.

Pour the dry mix into the wet mix. Combine just enough to bring it together, leaving a thick batter (avoid overmixing). Spread evenly into the prepared tin and bake for around 40-45 minutes, or until a toothpick shows just clingy crumbs.

Give the brownies time to fully cool on a metal rack. When in a hurry, pop it in the freezer for about 30 mins. Spread a generous layer of whipped caramel over the top, finishing with pinches of flakey sea salt.

To slice neatly, use a sharp knife warmed under hot water and dried off, cleaning it between cuts. Store extras in a sealed container at room temp for 2 days or in the fridge for up to a week.
