1
On a work surface, sprinkle about 1 1/2 tablespoons of the chocolate and 2 teaspoons of the nuts across each crepe.
-
2
Fold in half and into quarters to make triangular shapes.

3
In a large skillet, melt 2 tablespoons of the butter and 2 tablespoons of the sugar and cook over medium-high heat, swirling to melt the sugar.
-
4
Remove the pan from the heat.
-
5
Add 1/4 cup of the Nocello and 2 tablespoons of the brandy, return to the heat, and tilt the pan to ignite.
-
6
Return to the heat, add 4 of the folded crepes, and stir to coat evenly with the sauce.
-
7
Cook over medium heat, swirling, until the crepes are heated through and the chocolate inside is melted, about 2 minutes.
-
8
Arrange 2 or 3 crepes on each dessert plate and keep warm.
-
9
Repeat 2 more times with the remaining ingredients.

Sprinkle with the remaining chopped hazelnuts and garnish with cocoa powder.
-

Serve immediately.
-
13
Whisk together the flour, eggs, milk, sugar, salt, and 4 1/2 teaspoons of the butter to form a smooth, thin batter.
-
14
Refrigerate for at least 1 hour before proceeding.

Heat a heavy 6-inch skillet or crepe pan over medium-high heat.
-
16
When hot, brush with a light coating of the remaining butter.
-
17
Ladle about 1/4 cup of crepe batter into the pan, tilting the skillet to evenly coat the pan with batter.
-
18
Cook until golden brown on the bottom and the top begins to look dry, 1 to 2 minutes.
-
19
Using a spatula, carefully turn the crepe and cook on the second side just until the bottom colors slightly, about 30 seconds.
-
20
Transfer to a plate and cover loosely to keep warm.
-
21
Repeat with remaining batter.
-
22
Assemble as directed in Gianduia Crepes recipe, above.

23
(Or, make ahead and when cool, layer between sheets of waxed paper and wrap tightly in plastic wrap.
-
24
Refrigerate until ready to use, up to 3 days.)
-
25
Preheat the oven to 350 degrees F.
-
26
Spread the hazelnuts on a baking sheet.
-
27
Bake for about 10 minutes, stirring occasionally until the skins are cracked and the nuts (under the skins) are deeply golden brown.
-
28
Place the nuts in a towel and rub them to remove most of the skins.
-
29
Cool completely.
-
30
Combine the cream and 1 cup of the milk in a large heavy saucepan.
-
31
Scrape the vanilla bean seeds into the cream mixture, and add the bean and the hazelnuts.
-
32
Bring to a gentle boil over medium heat.
-
33
Whisk the yolks and sugar in a medium bowl.
-
34
In a slow, steady stream, whisk 1 cup of the hot cream mixture into the egg mixture.
-
35
Gradually whisk the egg mixture back into the saucepan.
-
36
Stir constantly over medium-low heat until the mixture thickens enough to coat the back of a spoon and reaches 170 degrees F on an instant-read thermometer, about 5 minutes.
-
37
Strain through a fine-mesh sieve into a heatproof medium bowl.
-
38
Discard the vanilla bean, and rinse the nuts in the strainer under cold running water; pat dry on paper towels.

39
On a work surface, crush the nuts with a meat mallet or rolling pin, and stir into the custard.
-
40
Stir in the remaining 1 cup milk and the liqueur.
-
41
Cover with plastic wrap, pressing the wrap against the surface of the custard to prevent a skin from forming.
