Instructions

Prepare the Sweet Potato Filling
Begin by boiling the sweet potatoes in a medium saucepan covered with water. Cook over medium-high heat for 20 minutes or until they are fork-tender. Drain the sweet potatoes and mash until smooth. Incorporate granulated sugar, brown sugar, evaporated milk, beaten eggs, vanilla extract, cinnamon, nutmeg, and salt until homogenous.
Bake the Sweet Potato Layer
Pour the sweet potato mixture into the pre-baked pie crust, evenly spreading with a spatula. Cover the pie loosely with foil to prevent the crust edges from darkening. Place on a baking sheet and bake in a preheated oven at 350°F for 45 minutes. Ensure the filling is set with a slight jiggle in the center before removing from the oven. Cool completely. This helps meld flavors together seamlessly.
Create the Haupia Layer
In a mixing bowl, whisk together coconut milk, 1/3 cup sugar, and cornstarch. Transfer to a medium saucepan and cook over medium heat, whisking constantly, until the mixture thickens and takes on a pudding-like consistency, approximately 7 minutes. Remove from heat and let it cool slightly. An advanced tip here is to ensure constant stirring to avoid lumps forming in the haupia.
Assemble the Pie
Gently spoon and spread the cooled haupia mixture over the sweet potato layer to form an even upper coating. Use a spatula for precision and smooth out the surface. Refrigerate the pie for at least 3 hours or until the haupia sets firmly. This time is critical for it to firm up properly and marry with the layer beneath.
Serve with Professional Flair
For a final touch, garnish with toasted coconut flakes before serving for an added texture contrast and flavor depth. Slice with a thin, sharp knife, wiping the blade between cuts for clean edges. Serve the pie chilled to indulge in its intended refreshing essence.
Tips and Tricks
- Opt for fresh sweet potatoes to ensure natural sweetness and creaminess that canned cannot match.
- If pressed for time, you can prepare the sweet potato filling a day in advance to enhance the flavors.
- Toasting coconut flakes accents the pie and can be done by spreading flakes on a baking sheet and baking at 325°F for 5–7 minutes, stirring occasionally.
Recipe Variations
- Add a layer of lightly toasted macadamia nuts between both layers for added crunch and flavor.
- Swap the pie crust with a graham cracker crust for a different textural experience.
- Use purple sweet potatoes instead for a vibrant visual twist and subtly different flavor profile.
- Infuse haupia with vanilla beans for a dotted aesthetic and rich floral undertone.
Frequently Asked Questions
- Can I use canned sweet potatoes?
Although canned sweet potatoes can be used in a pinch, using fresh sweet potatoes is greatly recommended for optimum flavor and texture. - Is the haupia layer essential?
Yes, the haupia layer is fundamental to achieving the classic sweet potato haupia pie experience through its refreshing, coconut-infused character. - How do I ensure a lump-free haupia?
Continuous whisking during the cooking of haupia is crucial for even texture, which prevents cornstarch from clumping as it thickens.
