Preheat the oven at 180 degrees Celsius.
Stir the margarine soft with a fork and mix it with the sugar.
Grate the almond paste and mix it with the margarine mixture. Add the almond flour and 1 egg and mix to a solid paste.
Divide the puff pastry roll in half and place one half on a baking paper.
Spread evenly the filling on the puff pastry. Leave approximately 2 centimeters free from the edge.
Place a figurine or a nut somewhere in the cake filling.
Whip 1 egg with a fork and brush the edge of the puff pastry with the filling.
Place the other half on top of the cake and cut the puff pastry evenly round around the cake.
Press the edge with a fork to get a nice pattern. Brush the top with the egg and make a nice pattern with a fork or a knife.
Place in the middle of the oven for approximately 50 minutes. Take the cake out and let it cool down.
Cut the cake before serving it so no one can cheat to find the figurine. The person who get the figurine in their piece will become king or queen of the day.
