Preheat the oven to 180 degrees C.
In a bowl, combine all your dry ingredients- flour, sugar, baking powder, salt and ground cinnamon. With a whisk, give it a good mix. Set aside.
With a fork, mash your ripened bananas very well, until you get a smooth, semi-liquid consistency. Don’t worry if there are some chunks left in it.
In a separate bowl, whisk the eggs.
Add the mashed bananas, vanilla extract and melted butter. Whisk well until it is all well-combined.
Add the wet ingredients to the dry ingredients and with a spatula, fold in everything together until the batter is just about well-mixed and lump free. Do not over mix or your bread can come out tough!
Lastly, throw in your chopped hazelnuts/ walnuts and give the batter a final mix.
Transfer the batter into a greased Loaf baking tin.
Sprinkle the top with pumpkin seeds and bake at 180 degrees C for around 40 minutes, or until the toothpick inserted in it comes out clean.
Cool, slice and enjoy as a delicious snack or a dessert!
