A puff pastry dough is mainly composed of butter, salt, water, and flour. Leavening agents are actually not required in this type of pastry. A puff pastry would usually puff due to the ways on how it is cooked. Pie crusts and wrappings for meat would use the puff savory pastry. While things like cream horns, Mille Feuilles, and palmiers use the puff sweet pastry. The best alternative for a puff pastry would be a croissant dough.
