Place softened butter and caster sugar in a large mixing bowl. Using and an electric handheld mixer, beat the mixture until light and fluffy.
Add the egg, vanilla bean paste, salt and sourdough discard and continue beating until combined.
Mix the flour and cornflour (cornstarch) in a separate bowl. Add the dry ingredients to the wet ingredients and, using a rubber spatula, mix just until combined.
Cover the bowl with plastic wrap or tea towel and chill for 20 minutes.
Divide the dough into 2 pieces.
Shape the first piece of dough into a flat disc and place it between two pieces of non-stick parchment paper or waxed paper. Using a rolling pin to roll the cookie dough between the two pieces of paper to 3-4mm thickness. Repeat with the second piece of dough. Fold the sides of the paper to protect the dough from drying out, stack them on top of each other and place them in the fridge for 4 hours (or up to 48 hours).
Preheat your oven to 170° C Fan. Line a couple of large baking sheets with parchment paper.
Take one piece of rolled-out dough and peel off the top sheet of the paper and dust it with a little flour. Invert it onto the floured sheet and peel off the cover piece of baking parchment.
Cut out shapes using a cookie cutter and arrange them on the prepared baking sheets.
Re-roll any scraps between two sheets of baking parchment.
Bake the cookies for 10-12 minutes, then leave them to cool on the baking tray, before decorating with icing, if you wish.
