Notes
Make the cake a day ahead for best flavor and texture.
For a gluten-free version, use a 1:1 gluten-free flour blend with xanthan gum.
Store in the fridge for up to 4 days or freeze for longer storage.
Use seedless raspberry jam as a time-saving alternative to the raspberry layer.
Dip knife in hot water and wipe clean between slices for a neat presentation.
Double the mousse for an extra thick layer if desired.
Can substitute raspberries with strawberries for variation.
