Secret Ingredient Dark Chocolate Cake Recipes

Steps:

• For the cake: Preheat the oven to 350 degrees F. Grease a 10-cup Bundt pan with baking spray.
• Mix together the cake mix, milk, butter, eggs, chocolate chips and vanilla in a large bowl until completely combined. Pour into the prepared Bundt pan and bake until a toothpick inserted in the center comes out clean, about 40 minutes.
• Let the cake cool for about 15 minutes before turning it out onto a cooling rack. Allow to cool completely, an additional 20 to 25 minutes.
• For the simple chocolate ganache topping: Meanwhile, heat the cream in a small pan until just bubbling. Add the chocolate chips to a small bowl and pour the hot cream over the top. Let sit for 1 minute, then mix until smooth.
• Transfer the cake to a cake stand or serving platter and pour the ganache over the top, allowing it to drip down the ridges. Sprinkle with rainbow sprinkles and serve.

Steps:

• Make the cake: Preheat the oven to 350˚. Brush the bottoms and sides of two 9-inch round cake pans with vegetable oil and dust with flour, tapping out the excess. Whisk the flour, cocoa powder, salt, baking soda and baking powder in a medium bowl. In a separate medium bowl, combine the chopped chocolate and instant coffee; pour in the boiling water and let stand 5 minutes, then whisk until smooth. Combine the sour cream, vegetable oil and vanilla in a liquid measuring cup (it will look curdled).
• Beat the eggs and sugar in a large bowl with a mixer on medium speed until combined. Increase the speed to medium high and beat until light and fluffy, 4 to 5 minutes. Reduce the mixer speed to low and slowly add the coffee-chocolate mixture; beat until combined. Beat in the flour mixture in three batches, alternating with the sour cream mixture in two batches, until just incorporated. (Keep the mixer on low as you add the ingredients, then increase the speed to medium briefly between additions to beat out the lumps.) The batter should look like hot fudge.
• Divide the batter between the prepared pans. Bake until a toothpick inserted into the centers comes out clean, 35 to 45 minutes. Let cool 15 minutes in the pans, then run a knife around the edges and remove the cakes to a rack to cool completely.
• Meanwhile, make the frosting: Whisk the eggs, 1/4 cup milk, the sugar, cocoa powder, cornstarch and salt in a medium bowl until smooth (the mixture will be thick). Heat the remaining 1 1/4 cups milk in a saucepan over medium heat until just steaming. Gradually whisk the hot milk into the egg mixture, then pour the entire mixture into the pan. Bring to a boil, whisking (the mixture will become thick like pudding very quickly). Continue cooking 30 to 60 more seconds to thicken further, whisking vigorously, then remove from the heat. Pour into a bowl and press a piece of plastic wrap directly onto the surface. Refrigerate until cold, 3 to 4 hours.
• Put the chocolate in a microwave-safe bowl and microwave in 30-second intervals until melted; let cool slightly. Beat the butter in a large bowl with a mixer on medium-high speed until light and creamy, 3 to 5 minutes. Stir the cocoa pudding mixture to loosen, then gradually beat into the butter mixture, beating well after each addition. Beat in the melted chocolate. Continue beating, scraping down the sides of the bowl, until fluffy, 1 to 2 minutes.
• Trim off the domed tops of the cakes with a long serrated knife. Put one cake layer on a platter. Spread 1 cup frosting on top, then top with the other cake layer. Spread the remaining frosting over the top and sides of the cake. Refrigerate 1 hour before serving.

Steps:

• Arrange a shelf in the lower third of the oven, place a baking stone on it, and preheat the oven to 350°F/177°C.
• Spray VERY GENEROUSLY a 13 x 9 x 2-inch (33 x 23 x 5-cm) rectangular pan or two 9 x 2-inch (23 x 5-cm) round cake pans with nonstick cooking spray. Line the bottom of the round pans with parchment and spray on top of the parchment. With the rectangular pan, line and extend up the long sides with a piece of Release foil or parchment sprayed lightly with nonstick cooking spray.
• In a heavy saucepan, stir together the sugar, salt, cocoa, and baking soda. In another saucepan, bring 1 cup (237 ml) water to a boil. Stirring constantly, pour boiling water a little at a time into the cocoa mixture. It will bubble up at first and then get dark and thicken. Stir the cocoa mixture briskly. Place on the heat and bring back to a boil. Turn off the heat and allow to stand in the hot saucepan for at least 10 minutes.
• Pour the hot cocoa mixture into a mixing bowl. Add the oil and vanilla and beat on low speed for about 10 seconds. On low speed, beat the flour into the batter and then, with a minimum of beating, beat in the egg yolks, whole eggs, and buttermilk. This is a thin batter. Pour the batter into the prepared pan or pans. Place in the oven on the stone and bake until the center feels springy to the touch, about 25 minutes for round layers or 35 minutes for the sheet cake. Allow to cool in the pan for about 10 minutes on a rack. Run a thin knife around the edge and jar the edge of the pan to loosen. Invert onto the serving platter. Cool completely before icing.
