Sin Cake with Salted Caramel Sauce
Sin Cake Ingredients
- 7 tablespoons unsalted butter
- 14 ounces high-quality bittersweet chocolate
- 1/4 teaspoon coffee granules (I use whatever I have on hand at the time)
- 6 eggs
- 1/2 cup superfine sugar
- 1/4 cup dark brown sugar
- 1/4 cup light brown sugar
- 1 teaspoon pure vanilla extract
Salted Caramel Sauce
- 1/4 cup light corn syrup
- 2 tablespoons unsalted butter
- 1 cup heavy cream, divided
- 1 teaspoon salt
- 1 vanilla bean, split and beans scraped into a bowl
Fleur de Sel, to garnish
Preheat the oven to 350°. Grease a 9-inch round cake pan and line with parchment paper cut to fit the bottom of the pan. Set the prepared pan inside a 12-inch pan.
In a double boiler, heat chocolate and 7 tablespoons butter until fully melted. Stir until smooth. Let cool for about 5 minutes.
In a large bowl, whisk together the eggs, coffee granules, the superfine sugar, dark brown sugar, light brown sugar and the vanilla until fully incorporated. Add the cooled chocolate mixture to the egg mixture; whisk until smooth. Pour the batter into the prepared 9-inch pan. Carefully fill the larger pan with water until it reaches about halfway up the side of the smaller pan. Tightly cover with aluminum foil.
Bake until top of cake is no longer sticky to the touch, about 90 minutes. Let cool for 10 minutes, then invert the cake onto a plate to cool completely.
To make the caramel sauce, In a heavy saucepan over medium heat, combine the light brown sugar, butter, corn syrup, ½ cup cream, and the salt and bring to a boil, stirring occasionally. Boil uncovered until the sauce is very thick and deep golden brown, 10 to 12 minutes. Stir in the remaining ½ cup cream and return to a boil, stirring constantly until the mixture is perfectly smooth. Stir in the vanilla beans. Pour sauce into a heatproof glass jar; refrigerate until just cool (about 2 hours) and spread a thick layer over the cake. Refrigerate the cake until fully cool, about another hour.
Sprinkle a little bit of Fleur de Sel over the cake to garnish.
