Method
Cake:
- Pre-heat oven to 350°F.
- Grease and line the bottom of three 8-inch round cake pans with parchment paper.
- Combine the flour, cornstarch, cocoa powder, baking soda, baking powder and salt. Whisk well until well combined. Set aside.
- Combine the buttermilk and vanilla; mix well and set aside.
- In a stand mixer with a paddle attachment, cream the oil, granulated sugar and brown sugar on medium speed for 3 minutes.
- Scrape the bowl down and add the eggs one a time, ensuring to scrape the bowl in between additions.
- Add 1/3 of the flour mixture and 1/3 of the buttermilk mixture. Mix on medium-low speed. Scrape the bowl down and repeat until all has been added.
- While the mixer is on medium-low speed, add the hot fresh brewed coffee.
- Scrape the bowl down and mix to ensure the batter is well combined. The batter will be loose.
- Divide evenly into the three 8-inch round lined cake pans.
- Bake for 20-30 minutes.
- Once the cakes have cooled for 30 minutes, remove them from the cake pan and wrap in plastic wrap. Freeze them overnight or chill for at least 4 hours before frosting.
Marshmallow Cream:
- In a stand mixer with a whisk attachment, whisk the egg whites until they are foamy.
- In a saucepan, boil the water and sugar until it reaches 240 F.
- Pour the hot syrup on the side of the bowl of the mixer while it is whisking at its highest setting.
- Continue to whip until the bowl is warm to the touch.
Ganache:
- Heat the heavy cream until it is simmering. This can be done on the stove top or microwave.
- Pour the hot heavy cream into the chocolate and let it sit for 5 minutes.
- Whisk it until it is well combined.
Assembly:
- The first and second layer should have 200 g of marshmallow cream each spread evenly.
- The top layer should have 150 g of frosting on top. Frost the sides, making sure to reserve some for decor.
- Pour the ganache on top, the viscosity should be similar to honey. If it is too thick, put it in the microwave in 5 second intervals. If it is too loose, put in the refrigerator in 5 minute intervals.
- Create the drip by lightly allowing the ganache to drip on the sides by pushing it with a spatula on the edge of the cake.
