Sweet and Salty Cake – adapted from Baked: New Frontiers in Baking
Cake Ingredients:
3/4 cup cocoa powder
2/3 cup sour cream
2 2/3 cups cups all-purpose flour, plus more for pans
2 teaspoons baking powder
1 teaspoon baking soda
1/2 teaspoon salt
3/4 cup (1 1/2 sticks) unsalted butter, softened, plus more for pans
1/2 cup vegetable shortening
1 1/2 cups granulated sugar
1 cup dark brown sugar
3 large eggs (at room temperature)
1 tablespoon pure vanilla
1/2 cup Salted Caramel
Whipped Caramel Ganache Icing
Fleur de sel, for garnish
Cake Directions:
1. Preheat oven to 325 degrees. Butter three 8-by-2-inch round cake pans. Line each pan with a parchment paper round, butter parchment paper and flour; set aside.
2. In a large bowl, whisk together cocoa, 1 1/4 cups hot water, and sour cream; set aside to cool, about 10 minutes.
3. In another large bowl, sift together flour, baking powder, baking soda, and salt; set aside.
4. In the bowl of an electric mixer fitted with the paddle attachment, beat the butter and shortening together until smooth and it appears to create strings inside the bowl, about 7 minutes. Add both sugars and continue beating until light and fluffy, about 7 minutes. Add eggs, one at a time, and beat until well incorporated. Add vanilla, scrape down the sides of the bowl with a spatula, and mix again for 30 seconds. Add flour mixture alternating with cocoa mixture, beginning and ending with flour mixture.
5. Divide batter evenly among the three prepared pans. Bake until cake is just firm to the touch and a toothpick inserted into the center of the cake comes out clean, 35 to 40 minutes. Let cool completely. I would actually chill the cakes, before frosting, in the freezer for about an hour – so that your frosting job/assembly job is easier. Believe me, the crumb layer is less fussy that way. In fact, you may not need to do a crumb layer and just assemble/frost the cake in one step.
6. Using a serrated knife, trim tops of cakes to make level. Place four strips of parchment paper around perimeter of a serving plate or lazy Susan. Place the first layer on the cake plate. Using about 1/4 cup of the caramel, spread a thin layer on the cake, allowing some of the caramel to soak into the cake. (This will happen ONLY if you trim the tops of cakes, otherwise, nothing will soak into your cake.) Follow the caramel layer with a layer of about 1 cup of the ganache icing. Place the second layer on top and repeat process with another layer of caramel followed by a layer of ganache icing (which you should chill before spreading on the cake, it’s too goupy at room temperature). Place the remaining layer on top of the second layer bottom side up. Spread entire cake with remaining ganache icing. Sprinkle with fleur de sel.
Salted Caramel
Makes enough for two to three 8-inch 3-layer cake
1 cup sugar
2 tablespoons light corn syrup
1/2 cup heavy cream
1 teaspoon fleur de sel
1/4 cup sour cream
Salted Caramel Directions:
1. Combine 1/4 cup water, sugar, and corn syrup in a medium saucepan; stir to combine. Bring to a boil over high heat. Cook until the mixture reaches 350 degrees on a candy thermometer, about 10 minutes.
2. Meanwhile, in another small saucepan, mix together cream and salt. Bring cream to a boil and cook until salt has dissolved, 3 to 5 minutes. Remove from heat and set aside.
3. When the caramel mixture has reached 350 degrees, remove from heat and allow to cool for 1 minute. Carefully add the hot cream to the caramel; stir to combine. Whisk in sour cream. Cool, and store in an airtight container, refrigerated, for up to 3 days.
Whipped Chocolate Caramel Ganache
Makes enough for one 8-inch 3-layer cake
1 pound dark chocolate, chopped
1 cup sugar
2 tablespoons light corn syrup
1 1/2 cups heavy cream
1 pound (4 sticks) butter, cut into tablespoon-sized pieces, softened but still cool
Ganache Directions:
1. Combine 1/4 cup water, sugar, and corn syrup in a medium saucepan; stir to combine. Bring to a boil over high heat. Cook until the mixture reaches 350 degrees on a candy thermometer, about 10 minutes.
2. In another small saucepan add cream and bring to a boil. Remove from heat and set aside.
3. When the caramel mixture has reached 350 degrees, remove from heat and allow to rest for 1 minute. Add the hot cream to the caramel; stir to combine. Let cool 5 minutes. Place chocolate in the bowl of an electric mixer and pour caramel sauce over chocolate. Let sit 1 minute before stirring from the center until chocolate is melted.
4. Attach bowl to electric mixer fitted with the paddle attachment and mix on low until the bowl feels cool to the touch. Add butter and increase speed to medium-high until mixture is well combined, thickened, and slightly whipped, about 2 minutes.
5. Cool the ganache for 20 minutes or so before frosting the cake for easier frosting.
