The story goes like this: On September 29, 2014, Swift posted a picture of cookies on her Instagram with the caption “Chai sugar cookies with cinnamon eggnog icing AKA Christmas in September.” “The quick and easy way is to make sugar cookies from a sugar cookie mix and just cut open a packet of chai tea and pour it into the batter as you make it,” Swift wrote. But recreating Swift’s idea of the perfect chai cookie isn’t too hard either: It’s still just a regular sugar cookie recipe with the addition of one tea bag’s worth of chai.
