Begin by blooming your gelatin sheets in cold water. Ensure the gelatin is covered. Leave to soak for 5-10 minutes
Add the cream, milk, sugar and nutella spread to a saucepan and bring up to just under a boil, stirring continuously.
Remove from the heat once the nutella has fully melted into the cream and milk mixture and bubbles just start to appear at the edges.
Remove the gelatine leaves from the water and squeeze out any excess water
Stir into the cream mixture until fully dissolved
Allow the mixture to cool to room temperature, stirring regularly to prevent a skin forming on the top.
Divide into dariole molds or ramekins and leave overnight in the fridge to set
To remove from the molds, place them in hot water for around 3 seconds to help release the puddings. Invert onto a dessert plate then garnish with chopped hazelnuts and dark chocolate shavings.
