Chocolate and Walnut Swirl Bread & Butter Pudding

Chocolate and Walnut Swirl Bread was a hit. Really tasty, but I left some slices for this. Yes, great leftover desert, good old bread and butter pudding. I had some slices of Chocolate and Walnut Swirl Bread that I baked yesterday and I needed the eggy mixture.
I googled it and found an interesting article. "How to make perfect bread and butter pudding" hmmm. I suppose everybody has an opinion of how they like their bread and butter pudding.
However, it's always safe to go back to Delia if you're not sure.
Her eggy mixture contains 3 eggs, 275ml milk, 60ml double cream and 50g sugar for 8 slices of bread. I had small slices of Chocolate and Walnut Swirl Bread, so I made the mixture with 2 eggs, 220ml milk and 30g sugar. I didn't add double cream because I didn't have it in my fridge.
