Salted Caramel Filling
- 1 cup sugar
- 2 tbsp light corn syrup
- 1/4 cup water
- 1/2 cup heavy cream
- 1 tsp Fleur de Sel
- 1/4 cup sour cream
For the Brownies
- 1 1/4 cups all-purpose flour
- 1 tsp salt
- 2 tbsp dark unsweetened cocoa powder
- 11 oz quality dark chocolate 60 to 72%, coarsely chopped
- 1 cup unsalted butter cut into 1-inch cubes
- 1 1/2 cups sugar
- 1/2 cup firmly packed light brown sugar
- 5 large eggs at room temperature
- 2 tsp vanilla extract
- For the caramel filling, combine the sugar and corn syrup with 1/4 cup of water in a medium saucepan, stirring carefully so as not to splash the sides of the pan. Cook over high heat until an instant-read thermometer reads 350F or until the mixture is dark amber in color, 6 to 8 minutes. Remove from the heat, and slowly add the cream, and then the Fleur de Sel. Whisk in the sour cream and set aside to cool. (Watch carefully over the stove as soon as the mixture starts turning golden brown because it will burn easily if you let it cook too high and too long. Also be sure to add the cream as soon as you remove from heat. I waited a few extra minutes and the caramel completely solidified and I had to start over.)
For the brownie, preheat the oven to 350°F.
- Butter the sides and bottom of a glass or light colored metal 9 x 13 inch pan. Line the bottom with a sheet of parchment paper, and butter the parchment.
- In a medium bowl, whisk together the flour, salt and cocoa powder.
- Place the chocolate and butter in the bowl of the 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 at this point.
- Add three eggs to the chocolate mixture and whisk until just combined. Add the remaining two 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.
- Sprinkle the flour mixture over the chocolate. Using a spatula, fold the dry ingredients into the wet ingredients until there is a just a trace amount of the flour mixture visible.
- To assemble the brownie, pour half of the brownie mixture into the pan and smooth the top with a spatula. Drizzle about 3/4 cup of the caramel sauce over the brownie layer in a zigzag pattern, taking care to make sure the caramel does not come in contact with the edges of the pan or it will burn. Use your offset spatula to spread the caramel evenly across the brownie layer. 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 an extra 1 1/2 teaspoons Fleur de Sel and 1 teaspoon coarse sugar. (I skipped this step)
Cool the brownies completely before cutting and serving.
