First, preheat the oven to 180°C top/bottom heat or 160°C convection.
Peel the bananas and put them in a bowl. Mash them with a fork.
Whisk the eggs and mix them with the bananas.
Add the sugar.
Melt the butter and whisk it into the banana-egg mixture as well.
Finally, add the dry ingredients: the flour, salt, cinnamon, and vanilla powder, and mix everything well.
Grease the baking pan with butter and pour in the mixture.
Bake in the preheated oven for 45 - 50 min.
If you want, you can refine the mixture with chocolate or fresh fruit.
Enjoy your meal!!!
