• Preheat your oven to 180 degrees celsius (fan-forced) and line two trays with baking paper.
• In the bowl of an electric mixer, add the butter, sugar and vanilla and mix until white and fluffy.
• Add the flour, egg and extra egg yolk and beat together to form a smooth dough (if using a mixer, use dough hook attachment, otherwise keep it on a slow setting if you don’t have one)
• Lightly knead the dough and wrap in glad wrap and pop in the fridge for 30 minutes - or if freezing, wrap in glad wrap and pop into the freezer.
• Roll out dough (thickness of 5mm) between two sheets of baking paper and using your choice of a cookie cutter (I use a 7cm round cutter for this recipe) cut out shapes and put onto baking trays lined with baking paper (add hundreds and thousands at this point if you wish).
• Bake in oven for 10-12 minutes or until golden at the edges. Allow the biscuits to cool on the tray for 10 minutes before transferring to a wire rack to cool completely.
• Decorate as desired
