Preheat the oven to 180c/350f.
Add all of the ingredients (except the toppings) to a large bowl and stir together to create a crumbly dough.
Fold a large piece of baking paper in half (big enough when folded to cover your baking tray), place the dough inside, cover with the other half of baking paper (this stops it sticking to the rolling pin), then roll it out as thin or thick as you like (we do around 0.2-0.3cms). The thinner the better for crunchier type cereal.
Lift the baking paper and then top with the cinnamon and coconut sugar (stir in a little bowl to combine). Roll once again just to help press the cinnamon & coconut sugar into the dough.
Peel back the baking paper (cut any excess paper), then use a knife or pizza cutter to cut in to small squares.
Place on a baking tray in the oven and cook for 15-20 minutes (depending on how thick you have made it).
Remove from the oven and allow to cool fully on the tray before breaking in to smaller pieces (it will feel a little soft to the touch but golden on the edges and it will firms up as it cools).
