Method
- Preheat your oven to 350 F/ 175 C. Line and grease three, eight-inch cake pans, or four, seven-inch pans.
- Combine flour, sugar, black cocoa powder, baking powder, baking soda, and salt in a large bowl. Whisk together until combined.
- In a separate, large bowl, add warm water, buttermilk, oil, eggs, and vanilla extract. Stir to combine.
- Pour the dry ingredients into the wet ingredients. Mix by hand until fully incorporated. The batter will be thin.
- Divide the batter evenly between the cake pans and bake for 24-27 minutes. Use a kitchen scale to weigh the pans for even layers.
- Remove cake layers from the oven and let them cool in the pans for 10 minutes. Loosen them with an offset spatula and flip onto wire racks to cool completely.
- Once cooled, level the top of each cake layer with a serrated knife. Wrap and freeze if making in advance.
- Beat butter on medium speed for 30 seconds until smooth.
- Add sifted black cocoa, vanilla extract, and salt. Mix on low until incorporated.
- Slowly mix in powdered sugar and heavy cream on low speed until combined.
- Mix in cooled, melted semi-sweet chocolate on low speed until fully incorporated and desired consistency is reached.
- Add black gel food coloring if a deeper black is desired. Cover frosting flush with plastic wrap to prevent crusting.
- Place semi-sweet chocolate chips in a heatproof bowl.
- Heat heavy cream in a heatproof bowl in the microwave for 45 seconds to 1 minute until steaming. Alternatively, heat on the stove until simmering.
- Pour hot cream over the chocolate chips. Let sit for 1-2 minutes.
- Add black gel food coloring, then stir slowly until smooth and combined.
- Set aside and cool for about 10 minutes, until slightly warm to the touch.
- Stack and frost the cake layers on a cake board, using a dab of frosting to secure the first layer.
- Add an even layer of buttercream between each cake layer with a large offset spatula.
- Spread a thin coat of frosting around the cake to cover the layers. Smooth with a bench scraper.
- Chill the cake for 30 minutes in the fridge or 10 minutes in the freezer until the frosting is firm.
- Add a second, thicker layer of frosting and smooth with a bench scraper.
- Chill the cake again for 20 minutes in the fridge or 10 minutes in the freezer until firm.
- Test the ganache consistency. If needed, gently warm it in the microwave for a few seconds.
- Add drips to the chilled cake using a squirt bottle or spoon.
- Decorate as desired. Pipe swirls on top with an open star tip, add sprinkles, or paint with edible gold paint.
