First of all peel the bananas and wash their peelings with a clean little brush in current water from your tap.Cut into small pieces as well as the fruit itself.
Get the blender,put the banana and the peel,add the eggs,the melted butter and the teaspoon of honey.Mix well,until it is smooth.
In a separated bowl mix all the other ingredients,sifting carefully.Let the raisins and macadamia for the end,just before the baking powder and the baking soda.Add the blender mixture and start stirring with a wood spoon,until it is all beautifully together.
Grease a medium baking sheet bread with butter and sprinkle a little of oat around its inside.Drop the mixture and turn on the oven in 240ºC. It´s going to take around 40 minutes to be baked.Although,use the stick technique in order to check if it is already firmly but softly baked.
While it is cooling down,make some tiny rolls using a firk on the bred surface, then ,once in a while, pour some sweetned warm milk over it,in order to provide a smoother crost in the end.
When it´s still warm ,take out from the baking sheet and sieve some confectioner sugar over it.Another idea is to decorate with some Nutella cream.
The best tip of all:serve with a generous portion of vanilla ice cream,and dare your family not to lick their lips and desperately ask for another portion!!!!!
