Pre-heat the oven to 160 degrees celsius
Break the frozen bananas into small pieces and put them in the thermomix. Blitz them on speed 8/9 for 1.5-2 minutes until they form a thick and creamy consistency a bit like ice-cream.
Set them aside in a separate bowl.
Add the butter, sugar and vanilla to the thermomix bowl and mix on speed 5 for 3 minutes. If the mixture sticks to the sides, then just scraping it back to the middle and continue beating until it is light and creamy.
Add the eggs one at a time and beat them on speed 5 for 10 seconds (each).
Add the banana mix with the maple syrup and combine everything on peed 5 for 45 seconds to a minute.
Add all the dry ingredients and fold together with a (non metal) spatular. You will have to do this by hand.
Once all the ingredients are combined, scoop the mixture into a lined baking tin and bake for 1 hour, or until a skewer/knife is placed in the middle and pulled out clean.
Serve with butter and enjoy.
