Method

Preheat the oven to 190C

The butter needs to be very soft – in the summer, room temperature is enough, but during the cold months, you  might have to soften it in the microwave

Place the butter and sugar in a bowl and beat until light and fluffy (around 5 minuets) using an electric whisker

Sieve in the dried ingredients and fold

Spoon into a piping bag fitted with a medium star nozzle

Free-style the piping. Uniformity only matters if you intend to sandwich the biscuits

Bake for 12-15 minutes until pale and just starting to colour at the edge

Leave to cool on a wire rack
