Preheat oven to 180C/350F/Gas 4 and grease 2 baking trays
Beat the butter until all light and fluffy and then add the sugar and vanilla extract.
Sift the flour and salt together and add this to the mixture along with the beaten egg.
Mix thoroughly to form a soft dough.
Break this up into 16 pieces and roll into balls just a little bit smaller than a golf ball/table tennis ball.
Pour the oatmeal on to a shallow plate and roll each of the dough balls in the oats to completely cover them. I like the pinhead oatmeal as it gives a nice spotty texture.
Place them on your baking tray spaced well apart as they will spread a bit and you don't want to end up with one huge biscuit/cookie! Push a cherry quarter into the centre of each ball but try not to press too hard as you don't want to flatten the balls.
Bake for approximately 15 minutes until they are golden and well risen.
Cool on a wire rack and then enjoy with a nice cup of tea or a glass of milk.
