Preheat oven to 375F.
Start by baking the puff pastry per package instructions until golden and crispy. If not already cut, cut into squares then bake.
Meanwhile mix together the milk, whipping cream, condensed milk, sugar, cardamom and cinnamon then place on medium heat and cook until just boiling (stirring frequently). Remove after a few seconds of boiling.
Once puff pastry has cooled, break into small pieces and place in a large casserole.
Layer with the nuts and shredded coconut, reserving some of each for garnish. Don't add the raisins yet or they will burn.
Pour the hot milk mixture over the casserole spreading evenly.
Spread the can of cream over the surface.
Bake in the oven for approximately 15-20 mins until hot and bubbling, then broil for 5-10 mins until surface is golden brown. Add the raisins a few minutes before removing from the oven to toast them.
Serve immediately, with nuts on the side for topping.
