incorporate butter and vanilla extract, mixing everything by hand, turning and squeezing through your fingers until a dough is formed.
roll out dough into a 25cm x 16cm rectangle (see post ⬆︎ for freezer bag hack) and put in the fridge for at least 30 mins.
when dough is solid, pre-heat oven to 160°C static.
remove the dough from the bag, place it on a chopping board lined with cling film or parchment paper, poke holes all over using a fork, then slice along the middle of the 16cm length and 10 times across, to obtain 22 rectangles ± 8cm x 2.2cm.
bake for about 10-12 mins or until golden brown around the edges.
allow the shortbreads to cool completely before handling.
