FAQs
1. Can I make this cake ahead of time?
Yes, you can make the cake a day in advance and assemble it the next day. Just store the cake covered in the fridge.
2. Can I use a different size pan?
Yes, you can. Just adjust the baking time. A smaller pan will take longer, and a larger pan will bake more quickly.
3. What can I do if the mousse is too thick?
If your mousse is too thick, you can gently fold in a bit more whipped cream to lighten it up. Make sure to do this slowly to maintain the fluffiness.
