A very easy twit pudding made with just 5 ingredients.
NOTES:
* I just made a double layer pudding with a layer of swiss roll and a layer of the twix custard sauce. You can make a 4 layer pudding too if you like.
* Swiss roll cake can be replaced with marie biscuit. For that, just soak the biscuits in warm milk and place in the dish.
* I made this with Twix chocolate bars, but you can use mars or snickers bar for this too.
