  • 3 large eggs room temperature
  • 1 tbsp vanilla extract 15ml

Method
 

Bake the Cake
  1. Whisk flour, black cocoa, sugar, and salt in a large bowl. Ensure no lumps remain.
  2. Mix eggs, oil, buttermilk, and vanilla. Slowly whisk in hot coffee.
  3. Divide batter into three 8-inch pans. Bake at 350°F (175°C) for 30-35 minutes.
Assemble the Mount Doom Cake
  1. Pour hot cream over chopped chocolate. Let sit 5 mins, then whisk until smooth.
  2. Stack layers with semi-set ganache. Create a rustic texture on the top and sides.
  3. Pour fluid ganache over the top to create thick, slow-moving drips.

Notes

Use black cocoa for the dark color.
Ensure coffee is hot to bloom the cocoa properly.
