In a sauce pan pour the milk, heavy cream and 1/2 cup of sugar. Cook until sugar dissolves

Meanwhile in a bowl add the egg yolks and 1/4 cup of sugar. Use an electric mixer and mix for 3-4 mins

Pour a little bit, 3/4 cup, of the hot mixture into the bowl. Mix together. Then pour that mixture back into sauce pan & cook on lowest setting for 8 more mins while stirring frequently

In a bowl add the nutella and spread it a little. Pour half of the hot mixture over a strainer and use electric mixer to mix together

add second half of hot mixture over a strainer to the bowl along with cinnamon + vanilla extract and stir with a spatula until blended together. ( looks like chocolate milk)

I dont have an ice cream machine, so i do the following after its ready

When its ready, I pour the mixture into a chilled bowl and put into the freezer. After every 30 mins stir lightly using a whisk until hardened.

When done and ready to serve you can add some bananas or chocolate syrup on top :)

Tip: if you want more of a gelato (dense texture), use 1 cup of cream and 2 cups of milk. For a more creamier texture, ice cream... Use 2 cups of cream and 1 cup of milk
