2 cups whole milk
1 cup heavy cream
1/2 cup sugar, plus 1/4 cup
4 egg yolks
1/2 teaspoon vanilla extract
1/2 cup chocolate-hazelnut spread (recommended: Nutella)
1/2 cup toasted hazelnuts, crushed
First thing you do; take the hazelnuts place on a baking sheet and insert this into a 350 degree oven for about 5 minutes. Remove from oven, and carefully place the hazelnuts into a dishtowel. Fold the towel together and rub the hazelnuts together. This helps remove the shell from the nuts. Remove the nuts from the towel, and shake out the towel into your garbage can (to remove the shells). Place the towel over the hazelnuts and using a meat tenderizer smash the nuts. Place the smashed nuts in a bowl, and set aside. Next, take the milk, heavy cream, and sugar and pour this into a small saucepan. Place over medium-low heat and cook just enough so the sugar dissolves. I just let it sit on the burner for about 3 minutes, stirring occasionally. Now, take the egg yolks and place into a standing mixture and whisk the yolks. Pour in half the milk mixture into the egg yolks and stir to combine. Pour the egg mixture into the saucepan. Cook this over low heat until the mixture becomes thick enough to coat the back of a wooden spoon about 10 minutes.
Now, take your nutella and vanilla and place this into a medium bowl. Place a strainer over the medium sized bowl and pour in your milk/egg mixture. Stir this until the nutella is nice and dissolved. Chill mixture for at least 5 hours (overnight is fine) until it's nice and cold. Follow your ice cream directions to finish it off. For mine; I poured in the nutella mixture into my ice cream maker and when it started to form into ice cream (about 15 minutes) I added in my hazelnuts. Enjoy!
