Decadent Hazelnut Tart with Chocolate Ganache

Start by preheating your oven to 180°C (350°F). In a large mixing bowl, combine the *hazelnut flour*, *all-purpose flour*, *powdered sugar*, and *salt*. Add the *softened butter* into the dry mixture and mix until the texture resembles coarse crumbs.

Next, incorporate the *egg* and knead the dough until it comes together smoothly. Press the dough evenly into the bottom and sides of a tart pan. Poke some holes with a fork to prevent bubbling, then place it in the fridge for about 30 minutes to chill before baking.

While the crust is chilling, prepare the hazelnut cream filling. In a mixing bowl, combine the *finely ground hazelnuts*, *sugar*, *heavy cream*, *eggs*, and *vanilla extract*. Whisk everything together until smooth.

Once the crust has chilled, pour the hazelnut filling into the crust. Bake it in the oven for 25-30 minutes or until the filling is set and slightly golden. Let it cool completely before moving to the next step.

For the ganache, bring the *heavy cream* to a simmer in a small saucepan. Remove it from heat and add the *chopped dark chocolate*. Let it sit for a few minutes to melt the chocolate, then stir until glossy and smooth.

Pour the ganache over the cooled hazelnut filling and smooth the surface with a spatula. Allow it to set at room temperature or refrigerate it for faster results.

For the final touch, whisk the *whipped cream* and gently fold in the *hazelnut spread* until well combined. This will create a delicious topping that complements the tart perfectly.

Spoon the chocolate cream over the set ganache and smooth it out for an elegant finish. Garnish the tart as desired and slice into servings. Enjoy your rich hazelnut tart with a cup of coffee!
