Sweet potato haupia pie

Sweet potato haupia pie is inspired by sweet potato pie originating from the Southern United States. However, it uses "Okinawan" sweet potatoes, a popular cultivar widely grown in Hawaii which makes for a vibrant purple filling. It is often mislabeled or mistaken for ube which shares a purple color but has a distinct flavor of its own. The filling is usually absent of the warm spices commonly associated with Southern sweet potato pie. It is topped with a layer of haupia (coconut pudding) and uses a macadamia nut shortbread base or short crust. Although it is called a "pie", it is usually prepared in rectangular pans as dessert bars, although a pie dish (or tart pan) can be used.
