Preheat oven to 160°C. Line baking tray with non-stick baking paper.
Combine the green banana flour, chocolate chips, rolled oats, sugars and cocoa powder in a large bowl.
Heat up the butter, golden syrup or honey and water in a small saucepan over medium heat until the butter melts and the mixture is smooth. Let it cool.
Stir in the bicarbonate of soda.
Add to the oat mixture and stir until well combined.
Form dough into balls and place them on the prepared trays. Flatten the balls. Bake for 15-20 minutes or until crisp. Leave to cool for 15 minutes before transferring to a wire rack to cool completely.
The biscuits will be slightly soft when you take them out of the oven. Don't be alarmed. They will harden and become more crispy after completely cooled down.
