Recipe Details

- Chill/Bake Time: 2 hours
- Total Time: 2 hours 20 minutes
- Servings: 8 to 10 slices
Ingredients
- 1 pre-made or homemade 9-inch tart crust (shortcrust or chocolate cookie crust)
- 10 oz dark or semi-sweet chocolate, finely chopped
- 1 cup heavy cream
- 1/2 cup smooth chocolate-hazelnut spread (such as Nutella)
- 2 tablespoons unsalted butter, softened
- 1 teaspoon vanilla extract
- A pinch of sea salt
- 1/3 cup roasted hazelnuts, roughly chopped (for topping)
Step-by-Step Instructions
- Prepare the Crust: Bake your 9-inch tart crust according to package or recipe instructions, then allow it to cool completely before filling.
- Make the Ganache Base: Place the finely chopped dark chocolate into a medium heat-proof mixing bowl.
- Heat the Cream: In a small saucepan, heat the heavy cream over medium-low heat until it just begins to simmer around the edges (do not let it boil).
- Pour and Melt: Pour the hot heavy cream directly over the chopped chocolate. Let it sit undisturbed for 2 minutes to allow the chocolate to melt.
- Whisk Until Smooth: Whisk starting from the center and working outward until the mixture is glossy, smooth, and completely combined.
- Incorporate Hazelnut and Butter: Whisk in the chocolate-hazelnut spread, softened butter, vanilla extract, and a pinch of sea salt until silky and uniform.
- Pour and Chill: Pour the rich chocolate filling into the cooled tart crust. Smooth the top with a spatula and scatter the chopped roasted hazelnuts around the edges or center.
- Set: Chill the tart in the refrigerator for at least 2 hours until the filling is firm enough to slice neatly. Serve chilled or at room temperature.

Frequently Asked Questions
- Can I make this tart ahead of time? Yes! This tart actually tastes even better when made a day in advance, giving the ganache time to set into a rich, fudge-like consistency.
- What is the best way to get clean slices? Dip a sharp knife into hot water, wipe it completely dry with a towel, and slice. Repeat the wiping process between each cut for professional-looking edges.
