Key Ingredients in this Chocolate Tart Recipe 

For the Granola Crust

• Chocolate granola – This is the star of the crust. It adds crunch, texture, and a subtle sweetness while keeping the crust hearty and rustic.
• Flour – Helps bind the crust together so it slices cleanly once chilled.
• Vegetable oil – Adds moisture and richness without needing butter.
• Agave nectar – A vegan-friendly sweetener that keeps the crust tender, not brittle.
• Unsweetened cocoa powder – Reinforces the chocolate flavor right from the first bite.
• Kosher salt – Balances the sweetness and intensifies the chocolate.
• Ground cinnamon – Adds warmth and depth, making the crust feel cozy and complex.

For the Tart Filling

• Instant espresso powder – Doesn’t make it taste like coffee; instead, it deepens and amplifies the chocolate flavor.
• Unsweetened cocoa powder – Creates a dense, truffle-like texture and bold chocolate base in this easy chocolate tart.
• Vegan dark chocolate – Adds richness and that melt-in-your-mouth quality we all love in a chocolate tart.  Make sure you use a good quality chocolate for this recipe 
• Agave syrup – Sweetens smoothly without overpowering the cocoa.
• Vanilla extract – Rounds out the chocolate and adds subtle sweetness.
• Vegetable oil – Keeps the filling silky, glossy, and perfectly sliceable once chilled.
• Salt – Essential for balance; it sharpens all the flavors and prevents the tart from tasting flat in this delicious vegan chocolate tart
• Fresh fruit – I used sliced strawberries, but you could use fresh raspberries or any other berries you’d like on this chocolate tart 

Step by Step Instructions to Make this Vegan Dark Chocolate Tart

Step 1: Prepare the Crust

Preheat your oven to 350°F.
In a food processor, pulse the crust ingredients: granola, flour, vegetable oil, agave nectar, cocoa powder, salt, and cinnamon until the mixture looks like wet sand and the oats are coarsely ground.

Next, firmly press the crust mixture into the bottom and up the sides of a tart pan with a removable base. Take your time here—pressing firmly helps the crust hold together beautifully.

Bake for 20–25 minutes, or until the crust smells deeply chocolatey and toasty. Transfer to a wire rack and let it cool completely.

Step 2: Make the Vegan Chocolate Ganache Filling

While the crust cools, dissolve the espresso powder in ¾ cup very hot water directly in the food processor. Add the cocoa powder and let it sit for 5 minutes—this step blooms the cocoa and gives the filling extra depth.

Then, add the melted chocolate, agave syrup, vanilla, vegetable oil, and salt. Process until the mixture is very smooth and thick, about 30 seconds.

Step 3: Assemble the Tart

Scrape the filling into the cooled prepared crust and smooth the top with a spatula. Gently tap the tart on the counter to release air bubbles. If any stubborn bubbles remain, use a toothpick to pop them and tap again to smooth everything out.

Step 4: Chill

Refrigerate the tart for at least 1 hour, or until the filling is fully set.  Place 

fresh berries and even some flaky sea salt (Maldon sea salt is my favorite!) on top right before serving.

This is an already impressive-looking tart, but you can make it even more stunning by adding sweet garnishes on top of the silky ganache filling like fresh strawberries or raspberries.  I took a heart cutter and shaped strawberry slices for a romantic touch for the upcoming holiday.

Storage Instructions

Serving tip: For the cleanest slices, let the tart sit at room temperature for about 10 minutes before cutting.  

Refrigerator: Store the tart covered in the fridge for up to 4–5 days.

Freezer: You can freeze the fully set tart (or individual slices) for up to 1 month. Thaw overnight in the refrigerator before serving.

FAQ and Expert Tips

Once the tart is filled and has cooled for at least an hour, use a hot knife to cut each slice.  I like to run my knife under hot water for 30 seconds and wipe off the water before cutting.  It ensures a clean cut each time.

If you’d like, you can also dust a little cocoa powder over the top for more texture on top.

Whether you’re making this for a dinner party, a holiday dessert table, or just because you’re craving something deeply chocolatey, this vegan dark chocolate tart with granola crust never disappoints. And if you ask me? It tastes even better the next day—straight from the fridge, fork in hand.
