On a plate, mix the demerara sugar with ½ tsp of ground cinnamon and set aside.
Spread the Nutella on 4 slices of bread and sandwich together with the remaining bread.
Cut off the crusts and slice each sandwich into 4 rectangles.
In a bowl, whisk together the eggs, milk, cream, vanilla extract and remaining cinnamon.
Add some butter to a frying pan to grease it and heat on a medium to high setting.
Dip each bread stick into the egg mixture and fry for approx. 3 minutes on each side, or until golden brown.
Immediately roll the sticks in the sugar and enjoy warm.
Tips
Your bread should be slightly stale. If the bread is too fresh, your French toast sticks will end up soggy.
If you don’t have any stale bread it’s easy to make some. Simply lay out your slices of bread on a baking tray and pop them in the oven at 180°C/160°C fan for 10 mins, turning them over halfway through. Allow the bread to cool before using.
