- 1 cup (2 sticks) unsalted butter, room temperature, plus more for pans
- 1/2 cup unsweetened Dutch-process cocoa (spooned and leveled), plus more for pans
- 2 cups all-purpose flour (spooned and leveled)
- 1/2 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 1/2 cups packed light-brown sugar
- 2 large eggs plus 2 large egg yolks, room temperature
- 6 ounces bittersweet chocolate, melted
- 1 teaspoon pure vanilla extract
- 1 cup low-fat buttermilk
- Dark-Chocolate Ganache
I didn't use eggs, brown sugar, or buttermilk. I also didn't throw in nuts because some of my officemates are allergic to it. I just used 1 cup of Mazola Veggie Oil and a cup of Cold Water. Feel free to make the recipe your own.
- Preheat oven to 350. Butter two 8-inch round cake pans; dust with cocoa, tapping out excess. Line bottom of each pan with a round of parchment paper; set aside. In a medium bowl, whisk together flour, cocoa, baking powder, baking soda, and salt; set aside.
- In a large bowl, using an electric mixer, beat butter and sugar until light and fluffy. Add eggs and yolks, one at a time, beating well after each addition; beat in chocolate and vanilla. With mixer on low, alternately add flour mixture in three parts and buttermilk in two, beginning and ending with flour mixture.
- Divide batter between prepared pans; smooth tops. Bake until a toothpick inserted in center of a cake comes out clean, 40 to 45 minutes. Cool in pans 15 minutes; run a knife around edge of each pan, and invert cakes onto a wire rack to cool completely.
- Set a rimmed baking sheet upside down on a work surface. Place one cake on sheet, and spread top with 1/3 of ganache. Place second cake on top, and spread remaining ganache over top and sides of cake. Using two wide metal spatulas, carefully transfer frosted cake to a serving platter.
