A friend posted two recipes on making bread and butter pudding. Here they are :

I used to make this 2 different ways:
1: buttered leftover bread cut into triangles and put overlapping into a dish with sides.
Sprinkle with raisins and sugar/sweetener.
Beat an egg into about 3/4 of a pint of milk and a pinch of salt, and pour over the bread.
Make sure it’s properly soaked.
Dot with butter and bake in a moderate oven until golden and crispy on top- probably about 30mins.

2: The posh version:
Use a brioche loaf.
Slice but don’t butter
Place overlapping slices in a dish with sides.
Sprinkle with chocolate chips or raisins and a little sugar or sweetener
Beat an egg into a mixture of single cream and milk with a pinch of salt.
Leave to soak. Dot with butter.
Bake in a moderate oven until golden and crispy on top- probably about 30mins
