In a large bowl or stand mixer beat the butter and sugar until creamy, approximately 2 minutes, sift the flour into the bowl and beat on low until almost combined.
Move the dough to a flat surface and gently knead to form a compact ball. Wrap in plastic wrap and chill for 1 hour.
Roll the dough into ¼-⅓ thickness and cut out with medium cookie cutters, place on parchment paper lined baking sheets. Pre-heat oven to 325F/163C, while the oven is pre-heating chill the cookies 15-20 minutes.
Bake the cookies for 10-12 minutes or until starts to brown around the edges. Let cool 5 -8 minutes on the baking sheets then move to a wire rack to cool completely. Enjoy!
Notes
The dough can also be rolled into a log shape and sliced and baking rather than cut out.Store baked cookies: After cooling completely, place brown sugar shortbread cookies in an airtight container and store at room temperature for up to a week. Freeze baked shortbread cookies: Place shortbreads in a freeze safe bag and freeze for up to two months. Thaw and enjoy.
