440gramsmashed bananaapproximately 500 ml or 6 bananas - the riper the better
5 mlbicarbonate of sodaapproximately 1 teaspoon

110gramschopped toasted walnutsapproximately 250 ml or 1 cup
Instructions
Heat the oven to 180 degrees Celcius or 160 fan / 350 F / Gas mark 4.
In a non-reactive bowl, mash the bananas and add the bicarbonate of soda and lemon juice and stir to combine. The lemon juice will activate the bicarb and cause it to froth. Set aside until required.
Beat together the butter and sugar until the sugar is dissolved and the mixture is light and creamy. This may take between 5-10 minutes depending on the type of cake mixer you are using.
Add the eggs one at a time and beat thoroughly between each addition.
Add the cardamom and mixed spice and ensure that you scrape the sides of the bowl to mix in all the butter and sugar at the bottom and sides.
Sift the flour and baking powder together three times then add the walnuts and toss together.
Add the flour to the butter mixture in three parts, alternately with the banana.
Spoon the batter into two 26 cm greased loaf tins and bake the loaves for 40-45 minutes.
Test for doneness after 40 minutes by inserting a toothpick into the middle. If it comes out sticky it needs to bake for a bit longer.
Alternately, you can use the same batter for muffins and bake for 20-25 minutes only.
It may require a shorter baking time if you are using a fan assisted oven.
Notes
If you want a more bread like texture you can add an additional 30 grams of sifted cake flour.
