Preheat the oven 210 degrees C
Grease a pie dish or cake tin with butter.
Cut the first puff pastry in a circle large than the base of the dish. The puff pastry will then cover the base of the pie dish and come up the side.
Combine all the filling ingredients and mix until well combine and smooth.
Spread the filling over the puff pastry base.
Add the figurine to a section of pie nearer to the outside.
Cut the second sheet of puff pastry to fit the top of the cake.
Seal the two sheets of pastry by pinching the edges together.
The cake traditionally has a pattern just barely scored into the pastry. Use a sharp knife to create a pattern on the pastry if you like.
Add some hole with the knife to allow the air to escape. Choose spots in the pattern where a hole may look appropriate.
