Pro Tips for Success
To get the best texture for your mousse, make sure your heavy cream is chilled before whipping. For the chocolate, let it melt slowly to avoid burning; stirring occasionally helps create a smooth consistency. If you want to get fancy, use a piping bag for your mousse layer for beautiful presentation!
Storage & Reheating
To store leftovers, simply cover the assembled cake with plastic wrap and keep it in the refrigerator for up to 3 days. You can freeze individual slices too! Just wrap them in plastic wrap followed by aluminum foil. To enjoy again, let the slices thaw in the fridge overnight for the best flavor and texture.
