Preheat oven to 180°C/350°F.
Cream together the butter and sugar in a stand mixer with the paddle attachment until light and fluffy. You could also use hand beaters or a large mixing bowl with a wooden spoon.
Add the vanilla and egg and beat together until combined.
Fold in the remaining ingredients until just combined.
Cover and refrigerate for about 30 minutes to allow the cookie dough to rest.
Roll the cookie dough into 3 tablespoons (60g) sized balls and place onto paper-lined trays, roughly 5-6 cookies to a tray to allow for spreading.
Bake at 180°C/350°F for 12-15 minutes and until golden around the edges.
Remove from the oven and allow to cool on the tray for at least 20 minutes.
Store any remaining cookies in an airtight container in the pantry or fridge.
