Method:

Place the milk, water, Classic fat spread, sugar and salt into a saucepan and bring to a slight boil over medium heat. Stir in the flour using a wooden spoon, until completely incorporated.
Remove from the heat and beat in the eggs, one at a time until you have a smooth batter.
Heat the oil and use an ice cream scoop, to scoop spoonfuls of batter into the oil. Fry until golden brown on all sides and roll into the cinnamon sugar.

Pour caramel into a piping bag. Make a hole into the donuts and pipe the caramel into the holes. Serve whilst still warm.
