Beat together the butter, tahini, sugar, salt, vanilla and eggs till nice and combined.
Add the rest of the ingredients and fold in well till all done.
Keep the batter in the fridge for 30 minutes - or bake outright.
Preheat oven to 180 degrees. Line a large baking tray.
Using a small ice cream scoop, take out some dough, shape and press slightly onto the tray. Makes around 15-16 cookies. Leave an inch space between the cookies. Bake for 10 minutes.
The cookie will still be soft when it is out, as it cools it hardens. Repeat till the whole batter is done.
Store in an airtight jar and enjoy. Makes around 20 cookies.
