Cut each sponge cake into two even layers. You will get 4 sponge discs.
Place the first disc on a flat serving dish, then cover with your icing and sprinkle a few raspberries on top.
Place a second sponge disc on top of the first one, then add another layer of icing and raspberries.
Repeat for the other two sponge discs.
Cover the entire cake with the remaining icing, carefully smoothing over the edges.
Decorate the outside of the cake with 24 French Macarons.
Keep the cake in the fridge for at least 24 hours before enjoying.
