Edmond’s cookbook is the staple in New Zealand households (antipodean Delia Smith?)
The original recipe calls for baking a quantity in 2 tins and sandwich with whipping cream. I prefer to bake in just 1 big tin, and also add dried fruit/nuts and some spice such as ginger or cinnamon.
4 ozs. butter
6 ozs. sugar
2 mashed bananas plus 1 for luck
1 level teaspoon soda
2 tablespoons boiling milk
1 teaspoon Edmonds baking powder
8 ozs. flour
Cream the butter and sugar, add the eggs, and the mashed bananas.
Then add the soda to the boiling milk (it will froth up). Gently stir the resulting froth into the banana mixture.
Lastly fold the flour & baking powder into the mixture.
Grease and line a 20cm/ 8″ round baking tin.
Fan Oven: approximately 35-40 minutes at 160C
Standard oven: approximately 40 minutes at 350F / 180C.
