You've never seen sweet potato pie like this before. Made with naturally purple sweet potatoes—no food coloring needed!—this classic dessert has a whole new look but the same great taste of the original.

Purple sweet potatoes (look for North Carolina-grown Stokes Purple) are a bit starchier and a little less sweet than regular sweet potatoes, which makes for a creamier, more subtle filling. We also added coconut milk to the filling for even more delicate sweetness. Top the sweet potato pie with a cloud of whipped cream and a sprinkling of toasted coconut flakes for a pretty presentation.

What Are Purple Sweet Potatoes?

If you happen upon purple sweet potatoes at the market, don't hesitate about grabbing them to use in casseroles, stews, soups, and of course, pies. The purple color is natural and thanks to anthocyanin, a type of flavonoid that gives these potatoes, and also cherries and grapes, their vibrant color. They have a slightly sweet flavor and creamy texture, and can be used interchangeably with standard sweet potatoes, although they may need additional cooking time.

What Is the Difference Between Ube and Purple Sweet Potatoes?

While ube might look like a purple sweet potato—they both sport purple flesh—there are a few key differences. First off, ube is actually a yam. Yams have rough, bark-like skin, compared to the thin, smooth skin of sweet potatoes.

The flesh of ube can also vary in color from light violent to dark lavender, while purple sweet potatoes are typically a deep purple. Ube is nuttier in flavor, and more moist in texture than purple sweet potatoes when cooked, making it excellent for baking applications.
