Preheat the oven to 180 degrees C
Grease a 2.5l ovenproof dish
Beat the sugar, eggs and vanilla for about 3 minutes until light and fluffy
Add the vinegar and jam and mix well
Sift the flour, bicarb and salt and mix alternately with the milk into the egg mixture, mixing well after each addition
Mix in the mashed bananas
Pour the batter into the dish and bake for about 35 – 45 minutes until cooked through and brown
Start making the sauce about 10 mins before the pudding comes out of the oven
Bring all the sauce ingredients to a boil while stirring, reduce the heat and keep warm
As the pudding comes out of the oven, prick it all over with a fork or toothpick
Spoon the hot sauce over the pudding
Let it stand for about 10 – 15 minutes until most of the sauce has soaked in (you can place the pudding back in the switched off warm oven to keep the pudding warm while it soaks)
Make the dukkah by placing all the ingredients in a food processor and pulse to a rough crumb (you can also chop it by hand)
Serve the malva with a sprinkle of dukkah and splash of custard
