Add the water to the milled flaxseed/linseed and leave it to plump up
In a large bowl, add the sugar, cinnamon, vanilla and oil and mix well.
Now add in the milled linseed/water mixture and mix well.
Add the flour, salt, baking powder and mix well.
Add in the oats and mix well.
Now add in the raisins and mix.
If you want chewier cookies, put the mixture into the fridge for 15mins-30mins to cool down. If you prefer a crunchier slightly flatter cookie, cook straight away!
Preheat the oven to 180°C / 350°F / Gas Mark 4.
Line two baking sheets with baking paper.
Put out tablespoons of mixture into vaguely round shapes onto the baking sheets. 8 cookies per sheet.
Bake for between 12-15 minutes (depending on your oven! You might need to swap the sheets around half way).
Cookies are ready when they are gently brown. Let cool a bit before eating!
