Purple Sweet Potato Cheesecake: A Stunning Twist on a Classic

A pecan-graham cracker crust holds a luxuriously silky, cinnamon-spiced sweet potato cheesecake — a colorful, festive twist on a classic dessert that’s perfect for the holidays. The vibrant purple from purple sweet potatoes makes this cake as eye-catching as it is delicious.

When I first saw Easy Vegan Cheesecake with Purple Sweet Potatoes by Eva Kosmas Flores, I was instantly inspired to riff on the idea. That gorgeous purple hue begged to be turned into a showstopping cheesecake — and the result balances stunning color with rich, cozy flavors.

Why this Recipe Works

• Saves time: No water bath required, so it’s simpler to make than many traditional cheesecakes.
• Slow-roasted sweet potatoes: Roasting concentrates the potatoes’ natural sugars and deepens their flavor.
• Layered richness: Mascarpone plus cream cheese, brown sugar and maple syrup, vanilla and warming spices create a silky, indulgent filling.
• Holiday wow factor: Purple sweet potatoes produce a beautiful, unexpected color that makes this cheesecake a festive centerpiece.

This cheesecake is almost as beautiful as it is delicious.

Food as art — and dessert that tastes as good as it looks.

How to Make This Sweet Potato Cheesecake

Make a pecan-graham crust in a food processor and par-bake it in a springform pan. Roast purple sweet potatoes until tender, scoop out the flesh, and combine it with mascarpone, cream cheese, sugar, maple syrup, spices and eggs. Blend until smooth, pour over the cooled crust, and bake. Chill to set and finish with your favorite garnishes.

Don’t be intimidated by cheesecake — mine is intentionally rustic, which means small cracks are fine. Skipping a water bath makes this recipe easier to prepare while still producing a creamy, flavorful texture.

Cook’s Tips

• If you’re short on time, a store-bought crust works well.
• Roast the sweet potatoes up to 3 days ahead; store the flesh in the refrigerator.
• Bring the cream cheese, mascarpone and eggs to room temperature (about 30 minutes) for the smoothest filling.
• Cool the cheesecake completely before slicing for the cleanest cuts.
• Chill at least 4 hours or overnight to ensure the cheesecake sets properly.

Friendly heads up: this sweet potato cheesecake riffs on my Amaretto & Mascarpone Cheesecake concept — same creamy foundation, but without amaretto and with sweet potato and warm spices added for seasonal flair.

Purple Sweet Potato Cheesecake with Pecan-Graham Cracker Crust

Ingredients

Graham Cracker Pecan Crust

• 10 graham crackers
• ½ cup pecans
• 6 tablespoons melted butter
• 3 tablespoons granulated sugar
• ½ teaspoon cinnamon
• ¼ teaspoon ground nutmeg
• ½ teaspoon kosher salt

Purple Sweet Potato Filling

• 1 pound (about 3 ounces measured after peeling) purple sweet potatoes
• 16 ounces mascarpone
• 8 ounces cream cheese
• 3 eggs, lightly beaten
• ½ cup brown sugar
• ¼ cup maple syrup
• ½ teaspoon cinnamon
• ¼ teaspoon nutmeg
• ½ teaspoon vanilla extract
• Pinch of kosher salt

For Garnish

• 2 tablespoons chopped nuts (pistachios, pecans, hazelnuts or walnuts)
• Fresh berries or pomegranate arils, as desired

Instructions

1. Preheat the oven to 400°F. Prick the sweet potatoes with a fork, wrap each in foil, place on a baking sheet and roast until very tender, about 1 to 1½ hours depending on size. Let cool until you can handle them, then peel and roughly chop into 1-inch pieces. Reduce oven temperature to 350°F.
2. Make the crust: Pulse graham crackers in a food processor until they form fine crumbs. Add pecans, sugar, spices and melted butter; pulse until combined. Press the mixture into the bottom and up the sides of a springform pan. Chill the crust in the fridge for 15 minutes, then bake for 10 minutes. Allow the crust to cool completely.
3. In a food processor or stand mixer fitted with the whisk attachment, beat mascarpone, cream cheese, vanilla, brown sugar, maple syrup, cinnamon, nutmeg and a pinch of salt until smooth, scraping the bowl as needed. Slowly add the eggs while blending, then add the roasted sweet potato flesh and continue mixing until fully incorporated and silky.
4. Pour the filling over the cooled crust and smooth the top. Bake at 350°F for about 1 hour to 1 hour 15 minutes, until the center is mostly set but still slightly jiggly. Turn off the oven, crack the door and let the cheesecake cool gradually to help prevent large cracks.
5. Chill the cheesecake for at least 4 hours or overnight to fully set. Before serving, garnish with chopped nuts, fresh berries, pomegranate arils or edible flowers as you like.

Notes

• A store-bought crust is fine if you’re short on time.
• Roasted sweet potato can be prepared up to 3 days ahead and stored in the refrigerator.
• Room-temperature dairy and eggs blend into a smoother filling — let them sit out for about 30 minutes before mixing.
• Allow the cheesecake to cool completely before slicing for cleaner slices.
• Store chilled for up to 3 days; this cheesecake is best after resting overnight.
