Step 1

Preheat the oven to 175°C. Lightly grease an 11cm x 22cm loaf pan and line base and 2 long sides with a sheet of baking paper, leaving 2cm overhanging.

Step 2

Sift flour, cinnamon, baking powder, soda and 1/2 teaspoon salt into a bowl with the brown sugar, then add the nuts.

Step 3

In a separate bowl, mash the bananas with a fork or potato masher, then stir in the eggs, vanilla extract and cooled melted butter. Using a rubber spatula or wooden spoon, fold the wet ingredients into the dry ingredients until they're just combined - don't overmix.

Step 4

Scrape cake batter into prepared pan. Place in the oven and bake for 1 hour or until golden brown and a skewer inserted in the centre comes out clean. Cool the loaf in pan 10 minutes, then turn out onto a wire rack to cool. Cut into 8-10 slices.
