This chocolate truffle tart has a crisp chocolate cookie crust and a smooth, intensely chocolatey ganache filling that sets into a soft, truffle-like texture. A little flaky sea salt cuts through the richness, while lightly sweetened vanilla whipped cream balances each slice.
Despite how impressive it looks, the tart is surprisingly simple. The crust takes about 10 minutes to bake, the ganache needs only a few ingredients, and the refrigerator does most of the work. It’s a good make-ahead dessert for Valentine’s Day, holidays, dinner parties, or anytime you want a serious chocolate dessert without making a layer cake.
What Chocolate Is Best for a Truffle Tart?
Because chocolate is the main flavor here, use one you genuinely enjoy eating on its own. A 60% to 70% dark chocolate gives the filling a rich flavor without making it overly bitter.
I like using a combination of bittersweet and semisweet chocolate:
- 8 oz bittersweet chocolate
- 4 oz semisweet chocolate
You can also use all bittersweet or all semisweet depending on how dark you want the tart. Bars generally melt more smoothly than chips because many chocolate chips are formulated to hold their shape during baking.
For another rich chocolate dessert, you can also try this Ghirardelli brownie recipe.
Ingredients
Chocolate Crust
- 1½ cups (about 170 g) finely crushed chocolate wafer cookie crumbs
- 4 tablespoons (56 g) unsalted butter, melted
Chocolate Truffle Filling
- 12 oz (340 g) dark chocolate, finely chopped
- 1½ cups (360 ml) heavy cream
- 4 tablespoons (56 g) unsalted butter, softened and cut into small pieces
- Flaky sea salt, for finishing
Vanilla Whipped Cream
- 1½ cups (360 ml) cold heavy whipping cream
- 1 tablespoon granulated or powdered sugar, plus more to taste
- ½ teaspoon vanilla bean paste or vanilla extract
- Pinch of salt
Instructions
1. Make the Chocolate Crust
Heat the oven to 350°F (175°C).
Mix the chocolate cookie crumbs with the melted butter until evenly moistened. The crumbs should hold together when pressed between your fingers.
Press firmly across the bottom and up the sides of a 10-inch tart pan with a removable bottom.
Bake for 10 minutes, then transfer to a wire rack and let the crust cool completely.
2. Make the Chocolate Ganache
Place the finely chopped chocolate in a heatproof bowl.
Heat the cream over medium heat until it is steaming and small bubbles appear around the edges. Don’t let it come to a full boil.
Pour the hot cream over the chocolate and leave it undisturbed for 2 to 3 minutes. Stir gently from the center outward until completely smooth.
Add the softened butter a few pieces at a time, stirring until the ganache is glossy and fully combined.
3. Fill and Chill
Pour the ganache into the cooled crust and gently smooth the surface.
Refrigerate for at least 3 hours, or until the filling is completely set. For the cleanest slices, chilling it for 4 hours or overnight is even better.
Sprinkle lightly with flaky sea salt just before serving.
4. Make the Whipped Cream
Combine the cold cream, sugar, vanilla, and salt in a chilled mixing bowl.
Beat until soft peaks form. Keep the whipped cream light and spoonable rather than whipping it until stiff.
Serve each slice with a spoonful of whipped cream.
How to Get Clean Slices
Because the filling is rich and fudgy, a warm knife makes a noticeable difference.
Dip a sharp knife into hot water, wipe it completely dry, and cut one slice. Clean and warm the knife again before each additional cut.
Letting the tart sit at room temperature for about 10 minutes before slicing also gives the ganache a softer, more truffle-like texture.
Tips for the Best Chocolate Truffle Tart
Chop the chocolate finely. Smaller pieces melt evenly when the hot cream is added and reduce the chance of unmelted pieces in the ganache.
Don’t boil the cream. It only needs to be hot enough to melt the chocolate.
Stir gently. Vigorous whisking can add air bubbles to the ganache and make the surface less smooth.
Cool the crust completely. Adding ganache to a warm crust can soften the cookie base and slow down the setting process.
Use flaky salt sparingly. You only need a little to sharpen the chocolate flavor.
Can You Make It Ahead?
Yes. In fact, this is one of those desserts that’s easier when made ahead.
Prepare the tart up to 2 days before serving, cover it once the ganache has set, and keep it refrigerated. Add the flaky salt and whipped cream shortly before serving.
Storage
Keep leftover chocolate truffle tart covered in the refrigerator for up to 4 days.
For the best texture, take individual slices out about 10 to 15 minutes before serving so the ganache can soften slightly.
Gluten-Free Chocolate Truffle Tart
Use a certified gluten-free chocolate cookie for the crust and check the chocolate label if you’re preparing the tart for someone who needs to strictly avoid gluten.
The ganache itself doesn’t require flour.
Dairy-Free Chocolate Truffle Tart
For a dairy-free version:
- Use dairy-free chocolate.
- Choose dairy-free chocolate cookies for the crust.
- Replace the crust butter with melted coconut oil or a dairy-free butter.
- Replace the heavy cream with full-fat coconut cream.
- Replace the butter in the ganache with a dairy-free butter or omit it.
Coconut cream will add some coconut flavor, so the dairy-free tart won’t taste exactly the same as the original, but the dark chocolate still remains the dominant flavor.
