Pre-heat the oven to 170c Fan, 190c Oven, Gas Mark 5

Line 2 baking sheets with non-stick baking parchment. Using a round cutter or bottom of a glass etc as a guide (I use a 5cm one but you can do around about this size), draw circles on each sheet of paper, spaced well apart and then turn the paper over to avoid getting ink or pencil on your biscuits.

For the wiggly ones you won’t need templates for these, just do it by eye.

Place the butter, vanilla and icing sugar into a bowl and beat until pale and fluffy. Then sift in the flour, cornflour and salt and beat until combined, although don’t over mix as you want them to be very delicate, not tough

Spoon the mixture into a piping bag fitted with a large open star nozzle (I’ve used a 1m). Pipe swirled rounds inside the circles on the baking sheets and any other shapes if you wish

Chill these for about 30 mins in the fridge before baking, so that they keep their shape/piping definition better.

Bake in the centre of the oven for approx. 12—15 minutes, until a pale golden-brown. Cool on the baking sheets for 5 minutes then carefully transfer to a wire rack to cool completely

For the filling and coating– I use vanilla buttercream (chocolate can also be used) and I pipe and fill them in various ways, the classic with jam.

You can use shop bought buttercream or make your own by beating together 50g of soft unsalted butter with 100g of icing sugar and a dash of vanilla extract or paste.

Dark or Milk Chocolate for dipping, approx. 100g of each in a small bowl (the bowl/s needs to be just big enough for dunking, but not so big that it’s too shallow to give a good depth on the biscuits). Melt chocolate in a bowl over hot water and dip.
