Method
Handful of dried banana chips and toasted coconut flakes to decorate (totes optional)
In a food processor, whizz all the nuts to a rough crumble.
Add the rest of the dry ingredients (not decoration ingredients, duh) and whizz for a few seconds to combine.
Chuck in the banana, oil and honey and pulse together, scraping down sides of bowl if you need.
Pour batter into a paper lined dish (mine was 24 X 15 cm) spreading evenly with back of a spoon.
Chuck on the banana chips and coconut, pressing them down gently to stick.
Pop the dish in the freezer for 2 hours.
Cut into squares and keep either in freezer or fridge.
