This Vegan Purple Sweet Potato Pie is a stunning twist on classic sweet potato pie, with a naturally vibrant purple filling, creamy texture, and warm notes of vanilla, cinnamon, and nutmeg. The purple sweet potatoes bring gentle earthy sweetness and beautiful color, while coconut milk creates a silky, luxurious filling without dairy or eggs. It’s an eye-catching dessert that feels both comforting and special.
Can This Vegan Purple Sweet Potato Pie Support Weight Loss Goals?
It can fit into a balanced eating pattern when enjoyed in moderate portions. Purple sweet potatoes provide carbohydrates and fiber, while using moderate amounts of sweetener and coconut milk helps control the overall calorie density. The pie is still a dessert, so pairing a smaller slice with fresh fruit can create a more balanced serving.
Does Vegan Purple Sweet Potato Pie Fit a High-Protein Lifestyle?
This pie is not naturally high in protein, but it can be adapted to become more protein-friendly.
Purple sweet potatoes provide fiber and carbohydrates, while silken tofu can add plant-based protein and create an exceptionally creamy filling.
A high-protein vegan crust or a small amount of suitable vanilla protein powder can further increase protein.
Because the crust and sweet potato contribute carbohydrates, this dessert is better suited to a balanced high-protein lifestyle than a strict low-carb plan.

My Personal Experience
- The color is what makes this pie so special.
Naturally purple sweet potatoes create a beautiful filling without artificial food coloring. - I love roasting the sweet potatoes instead of boiling them.
Roasting concentrates their natural sweetness and keeps excess water out of the filling. - A little vanilla makes the purple sweet potato flavor shine.
It gives the pie a warm bakery-style aroma without overpowering the sweet potato. - I always let the pie cool completely before slicing.
The filling firms as it cools, giving you cleaner, more beautiful slices.

- ½ cup (100 g) brown sugar
- 2 tablespoons maple syrup
- 1 tablespoon cornstarch
- 1½ teaspoons pure vanilla extract
- 1 teaspoon ground cinnamon

Vegan Pie Crust
- 1½ cups (190 g) all-purpose flour

- ½ cup (113 g) cold vegan butter
- 4–5 tablespoons ice-cold water
Optional High-Protein Addition

Ingredient notes: Purple sweet potato varieties differ in moisture and color. Roasting rather than boiling gives the richest flavor and helps prevent a watery filling.
Directions
- Prepare the oven — 5 minutes
Preheat oven to 200°C/400°F. Line a baking sheet with parchment paper. - Roast the sweet potatoes — 35–45 minutes
Arrange sweet potato cubes on the baking sheet. Roast at 200°C/400°F for 35–45 minutes, depending on size. Visual cue: They should be completely tender and slightly caramelized around the edges. - Cool slightly — 10 minutes
Allow the roasted sweet potatoes to cool enough to handle. - Prepare the crust — 10 minutes
Mix flour, salt, and sugar in a bowl. Cut in cold vegan butter until the mixture resembles coarse crumbs. Add ice water gradually until the dough just comes together. Texture cue: The dough should hold together without becoming sticky. - Chill the dough — 20 minutes
Shape into a disc, wrap, and refrigerate for 20 minutes. - Roll and shape — 5 minutes
Roll the dough into approximately a 12-inch circle. Transfer to a 9-inch pie dish. Press gently into the base and sides. Trim and crimp the edges. - Blend the filling — 5 minutes
Add roasted sweet potatoes, coconut milk, brown sugar, maple syrup, cornstarch, vanilla, cinnamon, nutmeg, ginger, salt, and lemon juice to a food processor. Blend until completely smooth. High-protein tip: Add the optional silken tofu and blend until fully incorporated. - Fill the crust — 2 minutes
Pour the purple filling into the prepared crust. Smooth the surface with a spatula. - Bake — 50–55 minutes
Reduce oven temperature to 180°C/350°F. Bake for 50–55 minutes. Visual cue: The edges should be set while the center still has a gentle wobble. - Cool completely — at least 2 hours
Place the pie on a cooling rack. Allow it to cool for at least 2 hours. Refrigerate afterward for an even firmer texture. - Serve
Slice with a sharp knife. Serve with vegan whipped cream, toasted pecans, coconut cream, or fresh berries.
