Decadent Vegan Chocolate Tart with Salted Oat Crust
Indulge in the rich, velvety perfection of this vegan chocolate tart, featuring a unique salted oat crust infused with a hint of warming cinnamon. This plant-based dessert, sweetened naturally with agave syrup, offers a luxurious experience for any occasion.
Embracing the Season with Sweet Indulgence
As the days begin to shorten and a subtle crispness enters the air, there’s a gentle shift towards the cozier comforts of autumn. I find myself gradually “dipping my toe” into fall, not quite ready for the full plunge into chunky sweaters and boots, but slowly welcoming the new season’s charm. My kitchen often reflects this transition; an unidentified orange squash might sit beside a bowl of late-season cherry tomatoes, freshly picked from our container garden. Last week, I even brought home a half-gallon of apple cider from the farmers market – small steps towards the heart of autumn.
Why rush into autumn’s full embrace when you can savor the transition? This philosophy extends to my desserts. When I first discovered this vegan chocolate tart recipe, I knew it was the perfect fit for this in-between period. It’s rich and satisfying, yet still feels fresh and not overly heavy, making it ideal for those lingering warm evenings or the first cool nights.
The Allure of This Vegan Chocolate Tart
What makes this vegan chocolate tart truly special? It’s an elegant symphony of textures and flavors. The moment I spotted it, I was captivated by its promise of rich, dark chocolate balanced by a unique crust. The inclusion of a subtle hint of cinnamon in the salted oat crust adds a warming complexity that perfectly complements the deep chocolate filling. It’s a dessert that feels both comforting and sophisticated, striking just the right balance for any occasion, from a casual family dinner to a festive gathering.
Preparing this tart is surprisingly straightforward. Thanks to the magic of a food processor, the cinnamon-spiced salted oat crust comes together in mere minutes, requiring minimal effort. This sturdy yet tender base provides the ideal foundation for the luscious, silky smooth chocolate filling. Sweetened with natural agave syrup, the filling boasts an intense dark chocolate flavor without being cloyingly sweet, allowing the quality of the chocolate to shine through.
The contrast between the robust, smooth chocolate filling and the delightful crunch of the toasted oats in the crust creates an irresistible textural experience that keeps you coming back for another slice. This tart isn’t just a dessert; it’s a testament to how incredible plant-based baking can be, proving that vegan treats can be every bit as decadent and satisfying as their traditional counterparts.

Instructions

Prepare the Crust: Preheat your oven to 350 degrees F (175 C). In the bowl of a food processor, combine the old-fashioned oats, whole-wheat flour, melted and slightly cooled coconut oil, agave syrup, unsweetened cocoa powder, kosher salt, and ground cinnamon. Pulse the mixture until it resembles wet sand and holds together when pressed. Transfer the mixture to a rectangular tart pan with a removable bottom (a 9-inch round tart pan can also work) and press it evenly into the bottom and up the sides of the pan. Bake for 20-25 minutes, or until the crust is golden brown and fragrant. Once baked, transfer the pan to a wire rack and let it cool completely before adding the filling. This ensures a firm crust.
-
Make the Chocolate Filling: In the same food processor bowl (no need to clean it thoroughly), dissolve the instant espresso powder in 3/4 cup of very hot water. Stir well to ensure it’s fully incorporated. Add the 1 cup of unsweetened cocoa powder and let the mixture sit for about 5 minutes; this blooming process enhances the chocolate flavor. Next, add the melted and slightly cooled vegan dark chocolate, the remaining 2/3 cup agave syrup, vanilla extract, 2/3 cup plus 1 teaspoon melted and slightly cooled coconut oil, and 1/4 teaspoon kosher salt. Process all ingredients until the mixture is incredibly smooth and thick, which should take approximately 30 seconds. Pour the rich chocolate filling into the cooled tart shell. Gently tap the tart pan on your countertop a few times to release any trapped air bubbles, ensuring a perfectly smooth surface. (You might have a small amount of extra filling, which makes excellent truffles if rolled and coated in cocoa powder!)
-
Add Toasted Oat Topping and Chill: In a small skillet, toast the 2 tablespoons of old-fashioned oats with the remaining 1 teaspoon of coconut oil over medium heat. Stir constantly for about 3 minutes until the oats are golden and fragrant. Remove from heat and stir in half of the demerara sugar, allowing it to melt slightly. Then, stir in the remaining demerara sugar. Let this oat mixture cool completely before sprinkling it evenly over the chocolate tart. Transfer the tart to the refrigerator and chill for at least 1 hour, or until the filling is firm and set. To achieve clean slices, use a hot, dry knife (run it under hot water and wipe dry between cuts). For the best texture and flavor, allow the tart to sit at room temperature for 15-20 minutes before serving. Store any leftover tart covered in the refrigerator.
Notes
This recipe is adapted from a delightful version found in Bon Appetit‘s October 2015 issue, with minor adjustments for optimal flavor and texture.
For an extra boost of chocolate flavor, ensure you use high-quality vegan dark chocolate (70% cocoa or higher is recommended) for the filling. The espresso powder doesn’t make the tart taste like coffee, but rather deepens and enriches the natural cocoa notes.

Tips for Perfecting Your Vegan Chocolate Tart
Achieving a bakery-worthy vegan chocolate tart is easier than you think with a few key tips:
- Crust Consistency: When pulsing the crust ingredients, aim for a “wet sand” texture. It should hold together when you squeeze a small amount between your fingers. Don’t over-process, as this can make the crust tough.
- Even Pressing: Ensure the crust is pressed evenly into the tart pan, especially up the sides. This prevents cracking and ensures a uniform bake.
- Cooling is Crucial: Allow the crust to cool completely on a wire rack before pouring in the filling. A warm crust can cause the filling to melt or become oily. Similarly, the tart needs ample chilling time for the filling to set properly, resulting in those clean, beautiful slices.
- Optimal Filling Texture: Make sure your melted vegan dark chocolate and coconut oil are only slightly cooled, not hot, to prevent curdling the mixture. Process until the filling is absolutely smooth and homogenous. The espresso powder is a secret weapon; it amplifies the chocolate flavor without adding a coffee taste, so don’t skip it!
- Serving Temperature: While the tart must be chilled to set, serving it straight from the fridge can make the filling too firm. Letting it sit at room temperature for 15-20 minutes before serving allows the chocolate to soften slightly, enhancing its creamy texture and flavor.
- Clean Slices: For presentation, dip your knife in very hot water and wipe it dry between each slice. This technique creates impeccably clean cuts through the rich filling and crisp crust.
Creative Variations & Serving Suggestions
While this vegan chocolate tart is a showstopper on its own, a few additions can elevate it further:
- Fresh Fruit Toppings: Brighten up the rich chocolate with fresh raspberries, strawberries, or sliced oranges. The acidity of the fruit provides a beautiful contrast.
- Vegan Whipped Cream: A dollop of coconut whipped cream or store-bought vegan whipped topping adds a light, airy counterpoint.
- Nutty Crunch: Instead of the toasted oats, sprinkle with chopped toasted hazelnuts, almonds, or pistachios for a different texture and flavor profile.
- Spiced Twist: Experiment with other warming spices in the crust, such as a pinch of cardamom or a touch of cayenne pepper for a subtle heat in the filling.
- Citrus Zest: Grate some orange or tangerine zest over the finished tart before chilling for a fragrant, bright note.
- Salted Caramel Drizzle: A homemade or store-bought vegan salted caramel sauce drizzled over each slice can take this tart to the next level of indulgence.
This tart pairs beautifully with a cup of freshly brewed coffee, a glass of plant-based milk, or even a glass of vegan dessert wine for a truly sophisticated experience.
Storage & Make-Ahead Tips
This vegan chocolate tart is a fantastic dessert to prepare in advance, making it perfect for entertaining or enjoying throughout the week.
- Refrigerator: Store the tart, covered loosely with plastic wrap or in an airtight container, in the refrigerator for up to 5-7 days. The flavors tend to meld and deepen over time, often tasting even better the next day.
- Freezer: For longer storage, you can freeze the tart. Once completely chilled and set, wrap the entire tart (or individual slices) tightly in plastic wrap, then in aluminum foil. It can be stored in the freezer for up to 1 month. Thaw overnight in the refrigerator before serving, allowing it to come to room temperature for 15-20 minutes for best texture.
- Make-Ahead Components: The crust can be baked a day in advance and stored at room temperature, covered. The filling can also be made a day ahead and stored in an airtight container in the refrigerator; gently reheat it over a double boiler or in the microwave in short bursts, stirring frequently, until pourable before assembling the tart.
