- STEP 1
Set oven to 180c and line a 8inch loaf tin with parchment paper.
- STEP 2
Take two of your three bananas and whisk them in a large bowl till they are smooth.
- STEP 3
Whisk in the vanilla, egg, yolk and sour cream till smooth.
- STEP 4
With a wooden spoon, beat in sugar and margarine/butter.
- STEP 5
Add the flour, baking powder, baking soda and salt, and gently fold in till only a few spots of dry ingredients remain.
- STEP 6
Add the chocolate chips, walnuts and the remaining banana chopped into chunks, reserving a small amount of the chocolate chips and walnuts, and fold into the mixture until just combined.
- STEP 7
Add the mixture to the tin and sprinkle the remaining chocolate chips and walnuts on top, pressing them in slightly.
- STEP 8
Bake for 45-50minutes checking until a tooth pick placed in the centre comes out clean.
- STEP 9
Allow to cool in the tin and then remove to a wire rack.
- STEP 10
Enjoy cold, warm with custard or a scoop of ice cream.
- STEP 11
Heat your oven to 100c, place your bananas on a baking tray and cook for 15 minutes - they should come out blackened and slightly soft.
Heat your oven to 130c, place your walnuts on a baking tray and toast for 10 minutes shaking halfway through - they should be browned and smelling toasted - chop these into medium to small chunks.
If things are looking to browned during cooking make a tin foil hat to rest on the top of your tin so the top isn’t exposed to the direct heat.
Go wild with your add-ins and toppings - I ended up putting butter and honey onto mine on a freshly cut slice (judge all you want).
