Preheat oven to 160°
Butter the bread and lightly butter an oven proof baking dish
Tear the bread in rough halves and layer on the dish, scatter with sultanas & sprinkle with cinnamon then layer the remaining bread on top (don’t put sultanas on top as they will burn)
Mix eggs, sugar, milk, and vanilla essence with a fork or whisk until combined
Pour onto bread & soak, pushing down gently so all bread is soaked and allow to sit for 10 minutes.
Bake at 160° for 45 minutes
Allow to sit briefly, then serve hot or cold
