right I've tweaked it and it seems to have made the biscuits crunchy.
Any changes I've made are in red font, so if you want chewy cookies ignore the red font. If you want crunchy, follow the updated red text.
"these amounts make 4 Cookies (2 days worth on PP and PV)
for attack, omit 1 tbsp wheat bran and lemon juice.
3 Tbsp. Oat BranVanilla essence or any other essence/spice
1 Tbsp. wheat bran
1 Tbsp. FF Yogurt 3/4 tbsp (three quarters of a tbsp)
1/4 tsp. Baking Powder
1 tsp. Lemon Juice 3/4 tbsp (three quarters of a tbsp)
Splenda, to taste (i use 3 or 4 tablespoons but I like them sweet)
Put all the dry ingredients in a bowl and stir. In another bowl mix the yoghurt with the lemon juice then add to the dry ingredients.
Place sheet of parchment paper on a baking tray
Lightly wet your hands with water so the dough doesn't stick to them when you pick up the dough to divide it into four even round balls.
Place the ball of dough on the parchment paper and flatten out so it is about 1-2 cm thick. Place the ball of dough on the parchment paper and flatten with the back of a wet tablespoon to 1cm thickness (thinner makes the biscuit crunchier)
bake in the oven for 15 mins @ 180 degrees celsius (gas mark 4)
30 mins @ 160 degrees celsius (just under gas mark 3)
THEN!!... take baking tray out of oven and TURN the biscuits over and put back in oven for ANOTHER 5 10 minutes. This makes the bottom of the biscuit crunchy .
leave to cool on a baking tray"
I hope this makes sense, give me a shout if it doesn't... x
