Slicing and filling the buns is optional, but oh so yummy! For variations to fill the buns, you could use marmalade, caramel, chocolate spread or even a few squares of chocolate! You could also pop in a few extra sultanas between each of the layers of bread, or mix it up with other dried fruit or nuts. Get creative with your fillings, they will all be delicious!
When making the pudding, I only turn the oven on after the whole thing has been assembled. This allows the pudding ten minutes or so to start to absorb some of the custard before baking. Keep pressing the buns down into the custard as you wait, encouraging them to soak up more liquid.
If you find the top of the buns (or indeed even the sultanas) are burning a little during baking, simply cover the whole tin with some foil and continue to bake,
Leave the pudding to sit, ideally covered with some foil, for about ten minutes before serving. This allows the pudding to cool enough so no one gets burned!
Make the pudding, without baking, up to a day in advance. The advantage this has is it will allow the bread to soak up all the delicious flavours from the custard too.
The hot cross bun bread pudding is best enjoyed within two days of baking. Reheat either for a few seconds in the microwave or covered with foil at 160C/320F for 8-10 minutes in the oven.
Serve with extra custard, ice cream or double cream, and include an extra dollop of your filling too if you wish!
