Add flour, salt, butter, sugar, egg, honey and vanilla essence to the food processor and mix till it's all well combined (Thermomix: speed 5/30 seconds)
On a well floured surface, and with well floured hands, shape balls the size of large marbles and space them out evenly on a tray. They will expand in the oven.
With your finger make a dent in each ball and fill it with the optional extras or leave it as is
Place in the oven and bake for 13 - 15 minutes depending on your oven
They will still be really soft when they come out the oven, so leave them to cool entirely before transferring to a biscuit tin
