Nutella Chocolate Tart

Ingredients:

Tart Crust:
1 and 1/4 cups all purpose flour (185 grams)
2/3 cup powdered sugar (75 grams)
1/4 teaspoon table salt
8 Tablespoons cold butter (113 grams)
1 egg yolk
1/2 teaspoon vanilla extract
1 Tablespoon heavy cream (30ml)

Filling:
1/2 cup heavy cream (120ml)
2 Tablespoons butter (30 grams)
pinch of salt
2 ounces bittersweet chocolate (60 grams)
10 to 12 ounces of nutella (285 to 340 grams)

Hazelnuts for decoration.

***Note... if you are going to make this (I suggest you do) please allow to warm more to room temperature before slicing and eating, at least 1 and 1/2 hours or 2 hours out of the refrigerator.
I decorated the tart with the nuts just before serving.
