Peanut Butter cookies (WARNING: may not make it out of the mixing bowl)

Oh my goodness, the batter for these cookies is TOO GOOD.

225gm butter (I used sunflower margarine)
100gm caster sugar
200gm soft brown sugar
2 eggs
1 tsp vanilla extract
240gm crunchy peanut butter
340gm plain flour
2 1/2 tsps bicarb soda
pinch salt
75gm dark chocolate, chopped

Cream butter and sugars together, add eggs one at a time (either by hand or with a hand beater). Add the vanilla and peanut butter and mix. Add flour, bicarb soda and salt and mix well until you have a delicious, fluffy, irresistible batter. Stir in the chocolate bits.

Fight the urge to eat every last bite and spoon onto greased baking trays. Cook for 10 minutes until just golden brown.

Makes about 24, depending on how much you managed to not eat in the making stage.
