The pie features a coconut filling (with pieces of actual coconut it seems) and a deep-fried chocolate-flavored shell.
Unlike the Black and White Burgers, there is no pie with a chocolate filling and coconut-flavored shell (at least not yet).
In case any of you find yourself overseas and want to try, the Black & White Pie is being offered for a limited time at participating McDonald's restaurants in mainland China through September 23, 2014. The price is 7 yuan (~$1.14 US) for one or 10 yuan (~$1.62 US) for two.
