Preheat the oven at 190°C/Gas Mark 5/375°F. Prepare an oven tray lined with greased or ungreased baking sheet.
Using an electric freestanding or hand mixer, beat the butter or coconut oil with sugar together until light and slightly fluffy.
Add the eggs, one by one mixing well after each egg.
In a separate bowl combine the oats with the flours and the salt. To this also add the baking soda and the soda bicarbonate combined with the vinegar or lemon juice.
Add gradually the flour mixture to the butter one mixing well at a low-speed until it is all nicely incorporated.
Add and stir in the dried berries and the chocolate chips.
With the help of a teaspoon shape the mixture into little clusters and place on the baking sheet in the prepared tray leaving tiny spaces (approximately 1 cm) between cookies.
Optionally once you have gone through half of the mixture add 3 to 4 tablespoons of desiccated coconut to the remaining half so you could have Sam with coconut if you fancy
Bake for 12-18 minutes (depending on their size) or until golden brown.
