Step 1

Preheat the oven to 180 C/ 350 F/ Gas Mark 4

Step 2

Put all the dry ingredients in a food processor and whizz to combine. Add the butter and whizz again until it starts to come together into a chocolate dough. Alternatively without a food processor you can mix the dry ingredients together  before rubbing the (cold)  butter in with your fingers or paddle attachment on your food mixer, until breadcrumbs form and finally kneading it into a dough.

Step 3

Empty out into an 8 " square ,or equivalent, lined loose bottomed tin and using a spoon gently press the dough evenly into the tin and smooth it off.

Step 4

Bake in the oven for about 25 minutes or until firm to the touch.

Step 5

Let the shortbread cool a little in the tin before marking out your slices. Wait until it is fully cool before moving to your serving plate and falling upon them.
