Chocolate Ganache Cake is a deliciously moist, 3 layered chocolate cake filled and topped with a decadent ganache frosting. Impress family and friends with this rich, chocolatey dessert.
Make the chocolate ganache. Add heavy cream to a large microwave safe bowl. Heat in the microwave for 60-90 seconds, until hot. Add chocolate chips and let them sit in the warm cream for 2 minutes, then mix together. If the chocolate isn't fully melted, microwave again for 15 seconds. Mix together until smooth, then add the melted butter and corn syrup, continuously whisking. Once all butter is incorporated, cover with plastic wrap and set aside to firm up. 3 cups Semi-sweet Chocolate Chips1 3/4 cup Heavy cream8 tbsp Salted butter3 tbsp Corn Syrup
Preheat oven to 325 degrees F. Spray 3 8-inch cake pans with nonstick baking spray or grease with butter and dust with flour. Set aside.
In a large bowl, whisk together all purpose flour, milk powder, baking soda, baking powder, and kosher salt. 2 2/3 cup All Purpose Flour2 tbsp Milk Powder1 tsp Baking Soda1 tsp Baking Powder1 1/4 tsp Kosher Salt
In a large microwave safe bowl, combine semi-sweet chocolate chips and butter. Microwave for 25 seconds, stir together and microwave for another 25 seconds. Stir together again until smooth. If the chocolate chips haven't fully melted, microwave for another 10-15 seconds. Whisk until smooth, be careful not to burn the chocolate. 1 cup Semi-Sweet Chocolate chips 1/2 cup Salted Butter
Add vegetable oil, sugar, and brown sugar and whisk for a full 2 minutes, until combined, this helps the sugars begin to dissolve and cools off the mixture so that it doesn't cook the eggs when adding (next). 1 cup Vegetable Oil3/4 cup Sugar1 cup Brown Sugar
Add in the eggs, vanilla extract, buttermilk, sour cream, and cocoa powder. Whisk together for another minute, until combined and smooth. 3 large Eggs1 tbsp Vanilla Extract1/2 cup Buttermilk1/2 cup Sour Cream2/3 cup Dutch Process Cocoa Powder
Add the dry ingredients to the bowl and mix until just combined, then pour in the hot coffee and continue to mix until the coffee is incorporated. 3/4 cup Coffee
Divide the batter equally among the 3 prepared cake pans. Bake for 30-35 minutes, until a wooden skewer inserted into the center of the cake comes out with just a few moist crumbs.
Allow the cakes to cool in the pan for 10 minutes, then turn over onto a wire rack. Wrap each cake with plastic wrap and allow them to cool completely - this traps in the steam, keeping the cakes super moist.
Once cooled completely, remove the plastic wrap from the cakes.
Place one of the cakes onto a cake stand and add 1/3 of the ganache on top of the cake and smooth into an even layer. Place the second cake on top and add another 1/3 of the ganache. Place the third layer on top and frost the cake with the remaining ganache.
Note: this cake is best served at room temperature. If storing in the refrigerator, allow it to come to room temperature about 1-2 hours before serving.
Notes
The longer ganache sits, the thicker it becomes which makes it easier to spread onto the cake. However, if the ganache becomes too stiff, warm ganache in the microwave in 15 second increments until the texture loosens up. 1-3 times should suffice.
