Place all the ingredients in a bowl. Set aside, stirring occasionally, for 20 minutes or until water has absorbed.
Preheat the oven to 160 degrees Celsius (140 fan forced).
Line two flat baking trays with non-stick baking paper.
Take half the mixture and add it as a ball in the middle of the first baking tray. Put a layer of plastic wrap over it and use a rolling pin to press the mixture firmly in a thin layer covering the tray. Ensure there are no gaps in the rolled out mixture and try and make sure your mixture is as square as possible so your crackers end up an even shape and size. The key is to key the layer of mixture as thin as possible.
Use a knife, score the mixture vertically and horizontally into the cracker sizes you'd like.
Bake for 1 hour or until golden and crisp.
Cool and break into pieces along the lines you've scored.
Store in an airtight container for up to 1 week.
