Tips & Variations

• If you prefer a dairy-free option, substitute the cream cheese and heavy cream with coconut cream and dairy-free cream cheese.
• Use dark chocolate chips in the ganache for a more intense chocolate flavor.
• Ensure the cake is completely cool before adding the mousse to prevent it from melting.

Storage

Store the cake covered in the refrigerator for up to 3 days. Allow the cake to come to room temperature for about 20 minutes before serving for the best texture. Leftover slices can be wrapped tightly and frozen for up to 1 month, then thawed overnight in the fridge.
