Preheat the oven to 170C. Grease an ovenproof dish lightly with butter.
Tip in the stale bread crumbs. Toss in the chocolate chips to spread evenly among the bread cubes.
Whisk together the eggs, brown sugar, cream and milk. Pour this mixture over the bread and press the cubes down to coat them in the liquid.
Leave all this to soak for 20 mins, then sprinkle with the granulated sugar and put straight into the oven for 50-60 mins. The pudding is ready when the custard has set and has a light wobble.
Let the dish stand for a while before serving - if you can!
