*Most of the mainstream brands that make puff pastry sold in stores don't use any actual dairy products which makes them accidentally vegan. However, be sure to check the ingredients list well if you are vegan or have allergies.
**If you are vegan and prefer to not make your own graham crackers you can replace the crumbs in this recipe with a number of lightly sweet cookies or crackers from the store. I think Nabisco makes grahams without honey but Speculoos and Biscoff Speculoos cookies, animal crackers, cinnamon teddy grahams, and Girl Scout's Thanks-a-lots are all vegan. Double check to make sure though.
