Ingredients

For the Tart Crust

1 1/2 cups all-purpose flour
1/2 cup unsalted butter, cold and cubed
1/4 cup powdered sugar
1/4 teaspoon salt
1 large egg yolk
2–3 tablespoons ice water

For the Ganache Filling

8 ounces dark chocolate (70% cocoa or higher), finely chopped
1 cup heavy cream
2 tablespoons unsalted butter, softened
1 teaspoon vanilla extract
Pinch of salt

Step-by-Step Instructions

Step 1: Prepare the Tart Dough

In a food processor, pulse together flour, cold butter, powdered sugar, and salt until the mixture resembles coarse crumbs.
Add the egg yolk and pulse briefly. Gradually add ice water, one tablespoon at a time, just until the dough comes together.

Form into a disk, wrap tightly in plastic wrap, and refrigerate for at least 30 minutes.

Step 2: Preheat the Oven

Preheat oven to 350°F (175°C).

Step 3: Roll Out and Blind Bake

On a lightly floured surface, roll chilled dough to about 1/8 inch thickness. Transfer to a 9-inch tart pan and press into edges. Trim excess dough.

Line the crust with parchment paper and fill with pie weights or dried beans.

Bake for 15 minutes. Remove parchment and weights, then bake an additional 5–7 minutes until lightly golden.

Allow the crust to cool completely before filling.

Step 4: Make the Ganache

Heat heavy cream in a saucepan over medium heat until it just begins to simmer (do not boil).

Place chopped chocolate in a heatproof bowl. Pour hot cream over the chocolate and let sit undisturbed for 2–3 minutes.

Stir gently from the center outward until smooth and glossy. Add softened butter, vanilla extract, and salt. Stir until fully incorporated.

Step 5: Assemble the Tart

Pour ganache into the cooled crust, smoothing the surface with a spatula.

Refrigerate for at least 2 hours, or until fully set.

Step 6: Garnish and Serve

Before serving, garnish with:

Fresh berries
Whipped cream
Chocolate curls or shavings
Flaky sea salt

Slice with a warm knife for clean edges. Serve chilled for a firm texture or at room temperature for a softer, silkier bite.

Tips for Success

Use high-quality chocolate – Since chocolate is the star ingredient, quality makes a big difference.
Finely chop chocolate – Helps it melt evenly when cream is added.
Do not overheat cream – Boiling cream can cause separation.
Cool crust completely – Warm crust may cause ganache to become oily.
Warm knife for slicing – Dip in hot water and wipe clean between cuts.

Flavor Variations

Espresso Infused – Add 1 teaspoon instant espresso powder to the cream.
Orange Zest – Stir in 1/2 teaspoon finely grated orange zest.
Salted Caramel Layer – Add a thin layer of caramel under the ganache.
Nut Crust Alternative – Replace 1/4 cup flour with almond flour for a subtle nutty flavor.

Storage

Refrigerate covered for up to 4 days.
Best served within 48 hours for optimal texture.
Can be frozen (well wrapped) for up to 1 month. Thaw overnight in refrigerator.

Why This Recipe Works

The buttery pâte sucrée-style crust provides a crisp, slightly sweet contrast to the intense richness of the ganache. The hot cream gently melts the chocolate, creating a stable emulsion that sets into a smooth, sliceable filling once chilled. A touch of butter enhances shine and mouthfeel, while salt balances sweetness and deepens chocolate flavor.

This Dark Chocolate Ganache Tart delivers bakery-quality results with surprisingly simple techniques. Rich, smooth, and beautifully refined, it’s a timeless dessert that never goes out of style.
