Prep pan - Grease and dust 2×7-inch or 2 x 8-inch round cake pans with softened butter or cooking spray and cocoa powder.
Coffee - In a large mixing bowl, combine boiling water and coffee. And set aside.
Dry ingredients - Combine white sugar, brown sugar, flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
Wet ingredients - In a medium bowl, whip the eggs with buttermilk, cooking oil, and vanilla extract. Then, add the oil followed by the eggs and vanilla. Combine well making sure to break the eggs and incorporate well.
Wet to dry ingredients - Pour the mixture of liquid ingredients into the dry ingredients (flour mixture) and combine well. Then, add the hot coffee and combine until you have a smooth batter with no lumps.Pro tip - Use a whisk to ensure you have no lumps and do not over mix.
Bake - Pour batter into the prepared pans. Bake in the center rack for about 25 to 30 minutes or until a toothpick inserted into the center comes out clean.
Cool - Let cool in the pan for 10 minutes. Then, invert onto a wire rack and let cool completely.
Chocolate ganache
Microwave - Chop the chocolate into smaller similar size pieces and place it in a large bowl or measuring cup. Pour the whipping cream over the chocolate. Add the butter and vanilla extract. Combine well. Heat in the microwave for a minute or more until all the chocolate is melted and smooth. Use a whisk to ensure it is smooth. Double boiler - Alternatively, you can heat the cream in a small saucepan over medium heat until it comes to an almost boil. Then, pour the hot cream over the chopped chocolate. Let stand for 2 minutes. Combine with a spatula until it is smooth.
Cover the ganache with plastic. Leave to set in the fridge for 2 hours or on the counter for 4 hours until it’s about peanut butter consistency.Pro tip- in summer you may need to place the ganache in the fridge to set. If it gets hard, place it in the microwave for no more than 10 seconds until you have a spreadable consistency.
Assemble
Prepare simple syrup - cool completely before using.Pro tip- Simple syrup is just sugar water that has been boiled and cooled. Used to keep cake layers moist.
Using a bread knife or cake leveler cut the domes off the cake layers. Brush each layer with the cooled simple syrupPro tip - you can also split each layer horizontally to make four layers
Then top the second cake layer on top followed by more ganache and the second layer. Top with a big dollop of chocolate ganache and spread with an off-set spatula
Whip the remaining ganache until it is light and fluffy. Pro tip - Don't overwhip as it can be difficult to smooth. If you do happen to overwhip add a few tablespoons of hot milk and whip some more.
Next, spread the whipped ganache on top or sides of the cake. Using a paddle motion when spreading will help smooth the ganache better. Place the cake in the fridge to chill for 10 to 15 minutes.Pro tip - A straight-edge spatula for the top, an offset spatula, and a bench scraper for the sides work better.
Chocolate glaze
In a microwave-safe bowl combine the chocolate and heavy cream. Combine until smooth. Set aside to cool until thick. Pro tip - Alternatively, you can place the chocolate and heavy cream in a small saucepan over medium heat until smooth.
Place the glaze in a piping bag or use a smooth to create a drip on the side of the cake. Once you have the desired drip effect pour the remaining glaze on the top and smooth it out with a spatula. Chill the cake in the fridge until the top is set. Pro tip - letting the glaze set will prevent the piped swirls from slipping off the cake.
Place the remaining whipped frosting in the piping bag with a star tip and pipe all around the cake. Top with chocolate curls.
Recipe Notes
The cake will stay fresh for up to 3 days at cool room temperature, and longer if kept in the fridge. It can also be frozen for a month.
Always wrap cakes well especially after cutting them to prevent them from getting dry.
When keeping in the refrigerator, place it in sealed silicon or ziplock bag or wrap in plastic wrap.
If stored in the freezer - first wrap in parchment paper, then place in a freezer-safe bag. Lastly, wrap in foil to prevent it from catching any freezer smells from other food. Always, thaw in the fridge overnight. The parchment paper keeps the condensation on the paper, not the cake.
