Method
- Preheat your oven to 175°C (350°F) and grease three 8-inch round cake pans.
- In a bowl, whisk together flour, cocoa powder, sugar, baking soda, baking powder, and salt.
- In another bowl, beat eggs, buttermilk, oil, and hot coffee until smooth.
- Pour wet ingredients into dry ingredients and mix until just combined.
- Divide the batter evenly into the pans and bake for 25–30 minutes until a toothpick comes out clean.
- Let the cakes cool in pans for 10 minutes, then turn onto racks to cool completely.
- Chill the cooled layers in plastic for 30 minutes before frosting.
- Chill mixing bowl and beaters, then beat cold heavy cream until soft peaks form.
- Fold melted and cooled chocolate into the whipped cream with the vanilla until smooth.
- Place one cake layer on a serving plate and spread a generous layer of mousse on top.
- Add the second layer, more mousse, and then the third; spread mousse to coat the sides.
- Chill the cake for at least 1 hour to set the mousse.
- Heat ½ cup cream in a saucepan until simmering, then pour over chopped chocolate.
- Let sit for 2 minutes, then stir until smooth and shiny. Allow to cool slightly.
- Pour the ganache over the chilled cake and pipe mousse rosettes on top; add chocolate chips for decoration.

Notes
To enhance flavor, always use hot coffee; it deepens the chocolate without adding coffee taste. Chill the cake layers for easier frosting and cleaner slices. If you have leftovers, store them covered in the fridge for up to 3 days; bring to room temperature before serving. To make it gluten-free, use a 1:1 gluten-free flour blend. For a healthier option, consider using whole wheat pastry flour or avocado in the mousse.
