This brownie is an elaborate affair. It involves a salted caramel filling and a whole bunch of different ingredients I don’t normally keep (heavy cream, sour cream, corn syrup), but the resoundingly positive response to these have been worth every minute of labor I put into these.
The texture is rich, fudgy, and just a touch gooey with the help of the salted caramel sauce filling and underbaking on my part. The directive on The Vanilla Bean Blog said to be sparse with the caramel, and due to my temporary shock at how much butter and sugar a 12×9 inch pan brownie contains, I was very sparing with it but definitely could have used more. I’m not that experienced in caramelizing sugar and the caramel sauce could have used more heat too.
I generally prefer to convert volume measurements (cups/spoons) into weight (ounces/grams) but this recipe must have been made with the homemaker’s cavalier measurement style in mind – using a 100g = 1/2 cup ratio for sugar meant that this brownie had almost a pound of sugar in a 12×9 pan and I freaked out and hastily retrieved maybe 1/2 cup/100g worth of brown sugar lumps to reduce the caloric content and the brownie still turned out perfect.
The fleur de sel and coarse sugar topping really makes the dish, so be sure to hunt down some turbinado sugar or the like.
1 cup sugar
2 tablespoons light corn syrup (I used dark brown corn syrup to no ill effect)
1/2 cup heavy cream
1 teaspoon fleur de sel
1/4 cup sour cream
for the brownie
1 1/4 cups all-purpose flour
1 teaspoon salt
2 tablespoons dark unsweetened cocoa powder
11 ounces dark chocolate [60-72%], coarsely chopped
1 cup [2 sticks butter], cut into 1 inch cubes
1 1/2 cups sugar (I used probably about 1 cup and it was completely fine)
1/2 cup firmly packed brown sugar
5 large eggs, room temperature
2 teaspoons vanilla
for the assembly
1 1/2 teaspoons fleur de sel
1 teaspoon coarse sugar
make the brownie
In a medium bowl, whisk together the flour, salt and cocoa powder.
Place the chocolate and butter in the bowl of a double boiler set over a pan of simmering water, and stir occasionally until the chocolate and butter are completely melted and combined. Turn off the heat, but keep the bowl over the water of the double boiler, and add both sugars. Whisk until completely combined and remove the bowl from the pan. The mixture should be at room temperature.
Add three eggs to the chocolate mixture and whisk until just combined. Add the remaining eggs and whisk until just combined. Add the vanilla and stir until combined. Do not overbeat the batter at this stage, or your brownies will be cakey.
assemble the brownies
Pour half of the brownie mixture into the pan and smooth the top with a spatula. Drizzle about ¾ cup of the caramel sauce over the brownie layer in a zigzag pattern, making sure the caramel doesn’t come in contact with the edges of the pan or it will burn. Use an offset spatula to spread the caramel evenly across the brownie layer, leaving about a ½-inch border around the edges. In heaping spoonfuls, scoop the rest of the brownie batter over the caramel layer. Smooth the brownie batter gently to cover the caramel layer.
Bake the brownies for 30 minutes, rotating the pan halfway through the baking time, and check to make sure the brownies are completely done by sticking a toothpick into the center of the pan. The brownies are done when the toothpick comes out with a few moist crumbs
Remove the brownies from the oven and sprinkle with the fleur de sel and coarse sugar.
