Preheat the oven to 160C fan / 180C and lightly butter a large oven proof dish.
Cut in half the hot cross buns and spread a thick layer of Nutella inside each one, put the top back on.
Place the hot cross buns into the oven proof dish.
In a large bowl mix together the cream, milk, eggs, caster sugar and vanilla till fully combined.
Pour the mixture over the hot cross buns and then sprinkle the chocolate chips on the buns and in the gaps.
Let it soak for 30 minutes if you can but don’t worry if you’re impatient!
Bake in the oven for 30-40 minutes or until the custard is more set, it can take a little longer sometimes I find. Enjoy!
