How to Make Purple Sweet Potato Pie with Coconut Topping
-
Prepare the pie crust according to your favorite recipe for blind baking. This step ensures a sturdy base for the rich filling you’re about to create.
-
Bake the wrapped purple sweet potatoes in foil at 180°C (356°F) for about 45 to 50 minutes until they’re tender. This step can even be done up to two days ahead to save time.
-
Preheat your oven to 175°C (350°F). Once the sweet potatoes are cool enough to handle, peel them and add to a food processor along with melted butter, evaporated milk, coconut milk, eggs, and vanilla. Process until you achieve a smooth and creamy texture.
-
Pour the luscious purple sweet potato filling into the cooled pie crust and bake for 40-45 minutes. If the crust starts to darken too much, cover it with foil. The pie is ready when a knife inserted comes out clean!
-
Cool the pie to room temperature for a few hours, or refrigerate it overnight for the best flavors to meld.
-
Make the haupia topping by combining sugar, cornstarch, and water (and rum, if you’re using it) in a bowl to form a slurry. In a medium pot, bring the coconut milk to a boil, then whisk in the slurry. Cook while stirring constantly for about 5 minutes until the mixture is shiny and has thickened.
-
Pour the coconut custard topping over the cooled sweet potato pie and generously sprinkle with toasted coconut for that perfect crunch.
Optional: Garnish with additional toasted coconut for an extra tropical touch.
