Method

Notes

These are guideline quantities, but keep the butter, oats and flour in these proportions.

Preparation

Bring the butter and egg up to room temperature.
Prepare the dough:
Cut up the chocolate bar into chunklets, each "square" makes 6 chunklets.
Lightly break up the walnuts.
Mix the flour and oats, and salt if needed, in a mixing bowl.
Pre-heat the oven to Gas Mark 4 / 180 Degrees C.
Put the sugars and butter into another bowl and beat together using a wooden spoon.
Add the vanilla extract and break in the egg and mix to a smooth paste.
Mix in the floury oats.
Add the berries, broken nuts and chocolate chunklets (and shavings), and fold using a spoon.
At this point you should have a good, solid biscuit dough, if not, pop the mixture in the fridge for 20 minutes.

Cooking

Prepare the cookies (2 batches)
Grease a baking tray.
Take a double teaspoon of mixture and roll it into a ball between the palms of your hand, and then squish it into a disc by pressing your palms together. Place the disc on a baking tray. My tray takes 4 rows of 4 discs; you need to give the cookies room to spread during the baking.

Bake in the top of the oven for 15 to 20 minutes until the cookies are golden brown.
Allow to cool on the tray for 5 minutes.
Transfer to a wire rack to finish.

Repeat for the second batch.
