Proper Mixing: Mix the cake batter until just combined to avoid overmixing, which can result in a dense or tough cake. Similarly, fold the raspberry mousse gently to maintain its light and airy texture.
Cooling Time: Allow the cake layer to cool completely before assembling the cake. This prevents the mousse from melting.
Chilling Time: Chill the cake in the fridge overnight so the mousse can firm up nicely.
Leftovers: Store any leftover cake in the refrigerator in an airtight container and enjoy it within a few days for the best taste and texture.
