Using a serrated knife, carefully slice each cake horizontally so you have 4 layers.
Place the first layer of cake on your cake stand and spoon a 1/3 of the mascarpone cream into the middle. Spread it out evenly using an offset spatula, being careful to take it right out to the edges (for presentation purposes!)
Add a layer of sliced strawberries on top of the cream, as neatly or messily as you wish.
Put the next layer of cake on, and continue spreading the mascarpone cream followed by the chopped strawberries between each layers.
When the top layer has been placed, dust over some icing sugar and top with whole strawberries and some edible flowers if you wish.
Enjoy!
