Line a 30cm x 20cm slice tin with baking paper
Preheat oven to 150 degrees fan forced, and place rack into middle of oven
Add the flours, oats or oat bran, sugar, coconut and salt to ™ bowl and mix 5 seconds / speed 3, stir mix around and repeat 5 seconds / speed 3
Put aside
Add butter and golden syrup or honey to ™ bowl and cook 6 minutes / Veroma / speed 2 / MC off
Add bi-carb soda and blend 10 seconds / speed 3 (mix will bubble up)
Return dry ingredients to ™ bowl and mix 10 seconds / reverse / speed 2
Scrape around bowl and repeat 10 seconds / reverse / speed 2
Remove mix to slice tin and spread out evenly (I use the back of a spoon to help level out the mix)
Place into oven and bake for 30 minutes until golden
Remove slice from oven and allow to cool completely before removing (NB: this can be done any time during the day, but you still need to place the slice back into the oven to completely dry out overnight after dinner)
Using the paper lining in the slice tin, lift the slice on to a cutting board
Keep the baking paper under the slice as you cut as you will need it to move the slice onto a baking tray to return to the oven to dry out
With a sharp knife (and I use a ruler too), cut the slice into desired pieces (I cut it into 8 slices across the tin, and 4 slices down the tin giving me 32 pieces)
Once cut slide the paper - with the slices on it - onto a baking tray
Use your knife to gently separate the pieces so that there is a little space between them
Preheat your oven to 150 degrees fan forced
Return slice to oven, switch it off and leave to dry overnight
Next morning remove slice from oven and store in a sealed container for up to two weeks
