Preheat oven to 180°C.

Grease a 12-hole muffin pan. Mash bananas in a bowl, then crumble in Weet-Bix and stir in the milk.

Set aside for 10 minutes. Meanwhile, beat together the eggs and margarine, then add to the banana mixture. Combine flour and sugar in a large bowl and add wet ingredients and choc chips.

Stir until just combined, then spoon into muffin pan and bake for 25 minutes until a skewer inserted into the centre comes out clean.
