Pastel de Nata, also known as Portuguese custard tart, is a beloved Portuguese pastry. In this innovative recipe, the flavors of Pastel de Nata are transformed into a creamy and refreshing ice cream. The base of the ice cream is made with a custard mixture infused with vanilla and cinnamon, just like the filling of the traditional pastry.
