When I first baked this Chocolate Hazelnut Tart, it was to impress a friend for her birthday. The rich chocolate filling poured over a nutty hazelnut crust was a total showstopper! I learned that letting the tart chill properly in the fridge really enhances the flavors, allowing them to meld beautifully.

I've experimented with different toppings over time, but I find that a sprinkle of sea salt balances the sweetness perfectly. The added crunch elevates the experience, making this tart not just a dessert but a memorable treat!

The Importance of Quality Ingredients

Using high-quality dark chocolate is crucial for achieving the best flavor in your Chocolate Hazelnut Tart. I recommend choosing chocolate with a cocoa percentage of at least 70% for a richer taste. The bitterness of the chocolate balances beautifully with the sweetness, enhancing the overall depth of the tart. Avoid using chocolate chips for melting, as they often contain stabilizers that can hinder smooth melting.

The hazelnuts play a dual role in this recipe. Not only do they provide a delightful crunch in the crust, but they also add a nutty flavor that complements the chocolate filling. If you can, toast the hazelnuts lightly before crushing them; this enhances their flavor and aroma significantly. Additionally, feel free to experiment with darker or lighter cocoa powder—each will impart different nuances to your tart.

Tips for a Perfect Crust

Getting the crust just right is essential. After pressing the crust mixture into the tart pan, make sure to use a flat-bottomed measuring cup or a glass to create an even surface. This helps prevent any air pockets that can form during baking, leading to a more uniform texture. Watch for the edges of the crust to turn a light golden brown, which indicates it's ready to come out of the oven.

If you're looking to add more flavor to your crust, consider incorporating a teaspoon of vanilla extract or a touch of cinnamon. These additions can elevate the taste profile and complement the chocolate filling beautifully. And if you're short on hazelnuts, feel free to substitute with almonds or walnuts, though the flavor will vary slightly.

Ingredients

Ingredients for the Tart

For the crust

1 1/2 cups crushed hazelnuts
1/2 cup all-purpose flour
1/4 cup unsweetened cocoa powder
1/4 cup sugar
1/2 tsp salt
1/2 cup unsalted butter, melted

For the filling

8 oz dark chocolate, chopped
1/2 cup heavy cream
1/4 cup sugar
2 large eggs
1 tsp vanilla extract
1/2 cup crushed hazelnuts for topping

Preparing the Ingredients

Instructions

Make the crust

Preheat your oven to 350°F (175°C). In a mixing bowl, combine crushed hazelnuts, flour, cocoa powder, sugar, and salt. Stir in the melted butter until the mixture resembles wet sand.

Press this mixture into the bottom and up the sides of a tart pan, then bake for 15 minutes.

Prepare the filling

In a saucepan, heat the heavy cream over low heat. Once warm, add the chopped dark chocolate and sugar, stirring until completely melted and smooth. Allow to cool slightly before whisking in the eggs and vanilla extract until well incorporated.

Assemble the tart

Pour the chocolate filling into the baked crust, smoothing the top with a spatula. Sprinkle the crushed hazelnuts on top. Bake for an additional 20 minutes or until the filling is just set but still slightly wobbly in the center.

Chill and serve

Remove the tart from the oven and allow it to cool at room temperature for about 10 minutes, then transfer it to the fridge to chill for at least 30 minutes before serving. Enjoy!

Pair with whipped cream or a scoop of vanilla ice cream for an extra treat!

Pro Tips

For an added twist, try incorporating a hint of orange zest into the chocolate filling for a citrusy surprise.

Serving Suggestions

Once your tart has chilled for at least 30 minutes, consider serving it with a dollop of freshly whipped cream or a scoop of vanilla ice cream. This contrast in temperature and texture enhances the experience of the rich chocolate. For a festive touch, grate some chocolate on top or sprinkle with a bit of sea salt to bring out the flavors.

If you want to impress your guests further, drizzle a bit of hazelnut or chocolate syrup on the plate before placing the tart. This not only improves presentation but also adds a splash of additional flavor. You can also pair this tart with a dessert wine, such as a late harvest Riesling, to complement its rich chocolate profile.

Storage Tips

To store any leftovers, cover the tart with plastic wrap or aluminum foil and keep it in the refrigerator. It will stay fresh for about three days, though the texture is best enjoyed within the first couple of days. If you're making this tart ahead of time for a special occasion, you can prepare it a day in advance and chill it overnight.

If you need to keep it longer, the tart can be frozen. Wrap it tightly in plastic wrap followed by a layer of aluminum foil. When you’re ready to enjoy it again, simply thaw it in the refrigerator overnight. Rewarming isn’t necessary, but if you do want it slightly warmed, place it in a 300°F (150°C) oven for about 10 minutes before serving.
