in a small bowl mix together the ⅓ cup sugar, cinnamon and cardamom and set aside.
Sprinkle the remaining ¼ cup sugar onto your work surface. Unfold the puff pastry and place over the sugar; Roll out the dough to about a 10x15 rectangle. Using a pastry brush spread the melted butter all over the pastry dough. Sprinkle the sugar cinnamon mixture evenly all over the top.
Start rolling along the long edge, tightly until reaching the middle. Then do the same on the other side, Roll tightly until the middle, meeting up to the other roll. You can wet your finger with water and gently press and seal the two rolls together.
Place the roll into the refridgerator for about 10 minutes until the roll becomes slighlty firm. PreHeat the over to 375℉. Line a baking sheet with parchment or a silpat.
Slice the chilled pastry into ¼ inch slices; place the 1 inch apart onto the baking sheet and then into the oven for about 12-15 minutes. Looking for golden and crispy. Let them rest briefly on the baking sheet and then transfer to a wire cooling rack. If they last that long. We ate them when they were still a bit warm. Absolutely delicious!
