This chocolate tart with orange marmalade and pistachios has been my showstopper for holiday gatherings and slow Sunday dinners. I first put these flavors together on a crisp December afternoon when I wanted a dessert that felt festive but was also dairy-free and straightforward to prepare. The combination of a pecan-date crust, a glossy chocolate filling made from firm tofu and vegan butter, and a bright layer of marmalade with crunchy pistachios creates a contrast of texture and flavor that keeps everyone coming back for another slice. The tart looks elegant but comes together without complicated technique, which is exactly the kind of dessert I like to make for friends.

What I love most is the balance: the citrus marmalade cuts through the richness of the chocolate, while the pistachios add a toasted, salty crunch that makes each bite lively. I usually make this when I want a dessert that travels well — it keeps its shape and texture in a cooler and slices neatly when chilled long enough. This recipe has turned casual dinner guests into dessert critics, and it sits at the intersection of comfort and sophistication in my baking repertoire.

Ingredients

• Crust: 2 1/2 cups pecans and 1 1/2 cups pitted Medjool dates (soaked in hot water for 5 minutes then drained) provide a naturally sweet, sturdy crust. Look for slightly soft, moist dates for easy processing.
• Crust flavoring: 2 tablespoons Dutch-process cocoa powder and 1/8 teaspoon fine salt deepen the chocolate notes; Dutch cocoa gives a rounder, less acidic cocoa quality than natural cocoa.
• Orange marmalade: 9 ounces (about 1 cup plus 1 tablespoon) of good-quality marmalade at room temperature — brands like Bonne Maman or Stonewall Kitchen work well, or use homemade marmalade for fresher orange brightness.
• Pistachios: 1 cup roasted salted pistachios, roughly chopped. The roasted, salted nuts give contrast to the sweet marmalade and creamy filling.
• Chocolate filling: 2 tablespoons cornstarch, 1 cup soy milk (divided), 3 tablespoons vegan butter, 16 ounces firm tofu (pressed and blended smooth), 3 tablespoons Dutch cocoa powder, 2/3 cup powdered sugar, and 2 teaspoons vanilla extract. The tofu base yields a dense, pudding-like texture without requiring dairy.
• Toppings (optional): fresh orange slices from 1 to 2 navel oranges, extra roasted pistachios (whole and chopped), and finishing salt like Sel de Gris or Maldon for a bright final touch.

Instructions

Prepare the pan and crust: Grease a 9-inch tart pan with removable bottom using a neutral oil or vegan butter. In a food processor, pulse 2 1/2 cups pecans until they form fine crumbs. Add 1 1/2 cups drained pitted dates, 2 tablespoons Dutch cocoa, and 1/8 teaspoon salt and blend until the mixture starts to clump. If it resists, add a tablespoon of water and pulse. The mixture is ready when it sticks together when pinched between two fingers. Press firmly and evenly into the bottom and up the sides of the greased 9-inch tart pan. Chill briefly while you prepare the marmalade layer. Layer marmalade and pistachios: Use a spoon to spread 9 ounces of orange marmalade over the bottom of the crust, keeping the marmalade about 1/4 inch away from the edges so the chocolate filling can seal to the crust later. Scatter 1 cup roasted salted pistachios evenly over the marmalade and press them gently into the jam to anchor them. Transfer the crust to the freezer for 10 to 15 minutes to firm up; this prevents the marmalade from mixing into the filling. Make a cornstarch slurry: In a small bowl, whisk together 2 tablespoons cornstarch and 1/4 cup of the soy milk until smooth and free of lumps. Set aside; this slurry will thicken the filling without graininess. Cook the chocolate filling: In a medium saucepan over medium heat, melt 3 tablespoons vegan butter. Add the remaining 3/4 cup soy milk, blended 16 ounces firm tofu, 3 tablespoons Dutch cocoa powder, and 2/3 cup powdered sugar. Whisk constantly to combine. Whisk the cornstarch slurry again, then pour it into the saucepan while stirring. Continue to whisk gently until the mixture thickens to a pudding-like consistency, usually 3 to 6 minutes. Remove from heat and whisk for another 3 to 5 minutes off the heat to smooth the texture, then stir in 2 teaspoons vanilla extract. Assemble and chill: Remove the crust from the freezer and pour the warm chocolate filling into the tart shell, smoothing the surface with a spatula. Let the tart cool at room temperature for 15 minutes, then transfer to the refrigerator and chill for at least 4 hours or overnight until fully set. Before serving, top with fresh orange slices, extra pistachios, and a sprinkle of finishing salt if desired.

Storage Tips

Store the tart covered in the refrigerator at 35 to 40 degrees Fahrenheit for up to 4 days. Use an airtight cake carrier or wrap the tart pan with plastic wrap to prevent flavor transfer. For longer storage, slice the tart into individual portions, wrap each piece tightly in plastic, then foil, and freeze for up to 3 months. Thaw overnight in the refrigerator, then bring to room temperature for 20 to 30 minutes before serving to restore creaminess. Avoid leaving the tart at room temperature for more than two hours due to the soft filling.

Ingredient Substitutions

If you have nut allergies, swap the pecan crust for a seed-based crust using 2 1/2 cups roasted sunflower seeds or pumpkin seeds and 1 1/2 cups dates. For soy allergies, replace the 16 ounces firm tofu and soy milk with 2 cups coconut cream blended for richness, though this will change the flavor profile. If you cannot find Dutch-process cocoa, use natural cocoa but add a pinch of baking soda to round the acidity. For a less sweet marmalade, use a reduced-sugar orange preserve or 3/4 cup of marmalade mixed with 2 tablespoons fresh orange juice.

Serving Suggestions

Serve slices chilled or at slightly cool room temperature with a simple garnish of fresh orange segments and a sprinkle of chopped roasted pistachios. For festive plating, add a spoonful of coconut whipped cream or a drizzle of warmed orange liqueur over each slice. Pair with black coffee, a bright black tea, or for an adult option, a splash of Cointreau or an orange-flavored dessert wine. This tart also makes a beautiful centerpiece for brunch or dessert tables during holidays.

Seasonal Adaptations

In winter, use Seville orange marmalade for a tart, bitter brightness that complements rich chocolate. In spring or summer, swap in a blood orange marmalade for a visually stunning, slightly floral note. During fall, replace pistachios with toasted hazelnuts and use an apricot or fig jam layer for a cozy, autumnal twist. Adjust garnish to match the season: candied orange peel in winter, fresh mint in summer, or a dusting of cinnamon in autumn.

Meal Prep Tips

Make the crust and marmalade layer up to 48 hours ahead and keep chilled; pour the filling on the day you plan to serve, then chill for a minimum of 4 hours. To streamline, press and freeze the crust while you prepare other components — a 10-minute freeze firms it quickly. Portion and label slices for grab-and-go desserts in airtight containers. Use shallow, rigid containers for frozen slices to prevent crushing the garnish and to speed thawing.

Success Stories

Readers have told me this is the tart that turned bakers skeptical of tofu into converts. One friend brought it to a potluck and was asked for the recipe three times; another served it for a dinner party where multiple guests declared it the best vegan dessert they had ever tasted. I remember a Thanksgiving when a picky relative who rarely eats sweets had two generous slices and later asked for the recipe — that moment made me a loyal advocate for this dessert.

This tart is an invitation to experiment and to share a dessert that feels elevated yet approachable. Try it, adapt it, and make it your own; the bright marmalade and crunchy pistachios will likely become a recurring request at your table.
