This High-Protein Purple Sweet Potato Pie gives classic sweet potato pie a nourishing upgrade without losing its creamy, warmly spiced character. Naturally vibrant purple sweet potatoes blend with silken tofu, plant-based protein, vanilla, cinnamon, and maple for a smooth, satisfying filling inside a crisp golden crust. It’s a beautiful high-protein vegetarian/vegan-friendly dessert that works especially well for holidays, meal prep, or an everyday sweet treat.
Can This High-Protein Purple Sweet Potato Pie Support Weight Loss Goals?
It can fit into a balanced weight-management eating pattern when portions are appropriate. The filling combines sweet potatoes with tofu and protein powder, providing more protein and fiber than a traditional pie. Because the crust, sweetener, and coconut milk still contribute calories, keeping portions moderate and pairing the pie with fresh berries can create a more balanced dessert.
Does High-Protein Purple Sweet Potato Pie Fit a High-Protein Lifestyle?
Yes, this version is specifically designed to be more protein-friendly than traditional sweet potato pie.
Silken tofu and vegan protein powder provide the majority of the added protein, while purple sweet potatoes contribute fiber and carbohydrates.
The recipe contains moderate net carbs because sweet potatoes and the crust remain significant carbohydrate sources.
For an even lower-carb option, use a nut-based crust and a reduced amount of sweet potato.

- ½ cup (120 ml) unsweetened soy milk
- ¼ cup (25 g) vanilla vegan protein powder
- ⅓ cup (65 g) maple syrup
- 1 tablespoon brown sugar or coconut sugar, optional
- 1½ teaspoons pure vanilla extract
- 1 teaspoon ground cinnamon
- ¼ teaspoon ground ginger
- ¼ teaspoon ground nutmeg
- ⅛ teaspoon salt
- 1 tablespoon lemon juice
- 1 tablespoon cornstarch
Protein-Friendly Crust
- 1 cup (100 g) almond flour
- ½ cup (60 g) oat flour
- 2 tablespoons vegan protein powder
- 2 tablespoons maple syrup
- 3 tablespoons melted vegan butter or coconut oil
- 1–2 tablespoons cold water, as needed
- ⅛ teaspoon salt
Ingredient notes: Use a vanilla protein powder that blends smoothly and isn’t strongly chalky. For a strictly gluten-free pie, use certified gluten-free oat flour. Soy milk and tofu provide additional plant protein.
Directions
- Preheat the oven — 5 minutes
Preheat oven to 200°C/400°F. Line a baking sheet with parchment paper. - Roast the purple sweet potatoes — 35–40 minutes
Spread the cubed sweet potatoes over the baking sheet. Roast at 200°C/400°F for 35–40 minutes, turning once halfway through. Visual cue: They should be completely tender with slightly caramelized edges. - Prepare the crust — 5 minutes
Mix almond flour, oat flour, protein powder, and salt. Stir in maple syrup and melted vegan butter. Add cold water gradually until a soft dough forms. - Shape the crust — 5 minutes
Press the dough evenly into a 9-inch pie dish. Prick the base lightly with a fork. - Pre-bake the crust — 10 minutes
Bake at 180°C/350°F for approximately 10 minutes. Remove and allow to cool slightly. - Blend the filling — 5 minutes
Add roasted sweet potatoes, silken tofu, soy milk, protein powder, maple syrup, vanilla, cinnamon, ginger, nutmeg, salt, lemon juice, and cornstarch to a food processor. Blend until completely smooth. High-protein cooking tip: Don’t add excessive protein powder to chase a higher number—the texture is best when the filling remains creamy. - Fill the crust — 2 minutes
Pour the purple filling into the pre-baked crust. Smooth the top with a spatula. - Bake — 40–50 minutes
Reduce oven temperature to 175°C/350°F. Bake for 40–50 minutes. Visual cue: The edges should be set while the center retains a slight gentle wobble. - Cool — 1 hour
Remove from the oven and cool on a rack for approximately 1 hour. - Chill — at least 1 hour
Refrigerate for at least 1 hour, preferably longer. The filling will become firmer and easier to slice. - Serve
Slice and serve chilled or at room temperature. Optional toppings include vegan Greek-style yogurt, berries, chopped pecans, or a small amount of coconut whipped cream.
