Frequently Asked Questions (FAQ)
1. Can I make this cake ahead of time?
Absolutely. In fact, this dessert tastes even better the next day after the mousse has chilled completely. It’s one of the best make-ahead dessert recipes for parties or holidays.
2. How do I store leftovers?
Keep refrigerated in an airtight container for up to 4 days. If frozen, let it thaw overnight before serving for best texture.
3. Can I make this recipe healthier?
Yes! Use dark chocolate with 70% cocoa or higher, reduce sugar slightly, and replace half the oil with unsweetened applesauce for a healthier dessert version.
4. What can I use instead of coffee in the cake?
You can substitute hot water, milk, or hot cocoa if you prefer to skip caffeine. Coffee simply enhances the chocolate flavor but doesn’t make it taste like coffee.
5. Can I use milk chocolate instead of dark chocolate?
You can, but the mousse will be sweeter and less intense. For balance, reduce sugar slightly if using milk chocolate.
