Dark Chocolate Sheet Cake Recipes

DARK CHOCOLATE SHEET CAKE WITH DARK CHOCOLATE FROSTING

Steps:

• Preheat the oven to 350 degrees F (175 degrees C). Grease a 10x15-inch rimmed baking sheet and line the bottom of the pan with parchment paper.
• Whisk flour, cocoa powder, baking soda, and salt together in a bowl until thoroughly combined. Set aside.
• Beat brown sugar, white sugar, and butter together in a large bowl with an electric mixer until light and fluffy. Beat in eggs one at a time, mixing well after each addition. Mix in vanilla extract. Add in 1/3 of the flour mixture, and mix until just combined. Add in 1/2 of the coffee and buttermilk, and mix until just combined. Continue alternating additions of the flour mixture with coffee and buttermilk, mixing just until combined. Pour batter into the prepared pan; smooth into an even layer. Tap pan firmly on the counter several times to remove air bubbles.
• Bake in the preheated oven until a toothpick inserted into the center of the cake comes out with a few moist crumbs, about 25 minutes. Do not overbake. Place cake on a wire rack and allow to cool completely.
• Meanwhile, make the frosting. Beat butter in a large bowl until completely smooth. Mix in cocoa powder, espresso powder, and salt until thoroughly combined. Mix in vanilla. Add in powdered sugar 1 cup at a time, mixing well after each addition. Pour in heavy cream and beat until frosting is light and fluffy, 2 to 3 minutes. If frosting is too thick, add more heavy cream.
• Spread frosting over the cooled cake.

Steps:

• Place a rack in the center of the oven and preheat the oven to 350 degrees.
• Grease and flour a 9x13" cake pan.
• In a large mixing bowl, place the cake mix, sour cream, water, oil, eggs, and vanilla. Mix with an electric mixer on low for 1 minute.
• Stop the mixer and scrape down the sides of the bowl. Increasing the mixer speed to medium, mix for 2 more minutes, until the batter is well blended.
• Pour the batter into the prepared pan, smoothing the top with a spatula.
• Bake the cake for 38 minutes. It's done when it springs back when lightly pressed with your finger. It might need up to 4 more minutes, depending on your oven.
• Remove the pan from the oven and cool, in the pan, on a wire rack.
• Frost with desired frosting.
