Transfer the dough to an oiled or floured surface.
Roll the dough into a 12×18 inch (30x45cm) rectangle.
Add the poppy seed mixture over the dough.
Spread the poppy seed mixture over the top of the rectangle.
Cut the dough into 12 equal strips.
Roll each strip up tightly.
Place the rolls on a parchment paper-lined (9×13 inch – 23x33cm) tray with 1 inch (2cm) distance between them to allow them to rise.
Cover with plastic wrap and let the rolls rise in a warm place for about 1-hour, until doubled in size. (if the tray is not too tall, you might need to grease the plastic wrap so it doesn't stick.)
Preheat the oven to 350°F (180C).
Bake the rolls for about 15-20 minutes until lightly browned.
In a medium bowl, add the cream cheese with powdered sugar, vanilla and lemon zest.
Mix to combine and spread over the warm rolls.
Enjoy while they are still slightly warm.
