Preheat oven to 175ºC.
Place butter into the Thermomix bowl and melt 2 min/75°C/seed 1. Cool slightly.
Add bananas, EVOO, eggs, vanilla, sugar, salt, nutmeg, and baking soda and powder, to Thermomix bowl and blend 10 sec/speed 8.
Add remaining ingredients and combine 12 sec/Interval. Finish combining with a spatula.
Pour into ungreased loaf tin(s) and cook 50-60 minutes until well set in centre. We usually get 1 large loaf and 2 mini loaves from the mix.
Leave to cool in tin for as long as you can resist, before turning out and slicing into thick slices to serve with slabs of butter….if you are doing it the Aunty Debbie way that is! Otherwise it is just as delicious without any butter.
I also force fed it to my kids, warmed up, as a dessert with Salted Caramel Custard…just to use it up, so I wouldn’t eat the entire thing on my own….Like I said, dangerous and addictive!
