These Cinnamon Swirls are not vegan, as there is a TON of butter in puff pastry dough, not to mention the butter you use to slather on top. That said, you could use a non-dairy butter alternative and vegan puff pastry dough with this recipe for a vegan version. You can find a few brands of vegan puff pastry dough in stores, but you can also use a vegan puff pastry dough recipe to make from scratch.
