Devil's Food Cake
This great devil's food cake recipe has been adapted from Martha Stewart Holiday Halloween 2007.
The Martha Stewart Show, October Fall 2007
FOR THE CAKE
- 1 1/2 cups (3 sticks) unsalted butter, plus more for pan
- 1 1/4 cups unsweetened Dutch-process cocoa powder
- 1 1/4 cups hot water
- 3 cups all-purpose flour
- 1 1/4 teaspoons coarse salt
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 2 1/4 cups granulated sugar
- 4 large eggs
- 1 tablespoon plus 1 teaspoon pure vanilla extract
- 1 cup sour cream
FOR THE FROSTING
- 6 tablespoons unsweetened Dutch-process cocoa powder
- 6 tablespoons hot water
- 1 cup (2 sticks) unsalted butter, room temperature
- 1/2 cup confectioner's sugar
- Generous pinch of coarse salt
- 1 pound semisweet chocolate, melted and cooled
- Make the cake: Preheat oven to 350 degrees. Butter two 8-by-2-inch round cake pans, line bottoms with parchment paper, and butter paper. Whisk together cocoa powder and hot water until smooth.
- Sift together flour, salt, baking powder, and baking soda; set aside. Melt butter and sugar in a saucepan over medium-low heat. Remove from heat, and transfer to a mixer. Beat on medium-low speed until cooled, 4 to 5 minutes.
- Add eggs, one at a time, beating after each addition. Beat in vanilla and cocoa-powder mixture. Reduce speed to low. Add flour mixture in two batches, alternating with sour cream and beginning and ending with flour. Beat until just combined.
- Divide batter between pans, and bake until a cake tester inserted into centers comes out clean, 45 to 50 minutes. Transfer pans to a wire rack to cool for 15 minutes. Invert cakes onto rack, peel off parchment, and let cool completely.
- Make the frosting: Whisk together cocoa powder and hot water until smooth. Beat butter, sugar, and salt in a mixer on medium-high speed until pale and fluffy. Reduce to medium-low speed; slowly add melted chocolate and cocoa-powder mixture, and beat until combined. If frosting is not set, let stand, stirring occasionally until thickened, 20 to 30 minutes.
- Using a serrated knife, trim tops of cake layers to make level. Transfer one cake layer to a cake stand, and spread with 1 cup frosting. Top with remaining cake layer, and coat top and sides with remaining frosting, spreading it in a swirling motion.
