Bake three layers of sponge cake at 350°F for about 25 minutes, until golden brown.
Let them cool completely on a wire rack before assembling.
In a chilled bowl, whip heavy cream until soft peaks form, usually around 3-5 minutes.
Combine raspberry jam and vanilla pudding in a small bowl until smooth.
Spread this mixture generously between each layer for a sweet surprise.
Place one layer on a serving platter and spread with jam and pudding filling.
Repeat with the second layer and top with the third layer.
Frost the entire cake with the whipped cream, smoothing it out evenly.
Roll out green marzipan to cover the cake, ensuring it’s smooth and even.
Decorate the top with fresh flowers or delicate marzipan roses for an elegant finish.
