In a medium saucepan, add arborio rice, granulated sugar, whole milk, heavy whipping cream, vanilla extract, and a charred cinnamon stick.
Set over medium-high heat. Stir often.
Once simmering, immediately reduce heat to medium-low. Let simmer and thicken, stirring occasionally, for 20-25 minutes or until rice is tender.
Pour into a bowl. Cover with plastic wrap. Fridge until room temperature or cooled completely.
Peel the banana and cut in half lengthwise and place on a foiled lined baking sheet. Coat with sugar. Place under a broiler until caramelized.
To plate, place a big dollop of rice pudding on the plate tapping on the bottom to flatten it out.
Top with banana and crushed pistachios. Dust with cinnamon before serving.
