1Cream the softened unsalted butter using an electric mixer.
2Add powdered sugar and beat until combined.
3Add vanilla extract and combine.
4Gradually add flour and salt while mixing until fully incorporated.
5Remove dough from the bowl, gently knead a few times on a surface until it forms a ball, and transfer to a greased 9 by 13 baking sheet lined with parchment paper.
6Press the dough into a rectangle and use a rolling pin or glass to shape it into an even layer in the pan.
7Bake in a preheated 325° oven.
8Remove from oven, slice the shortbread into rectangles while still warm, and poke holes along the top with a fork.
9Return to the oven, turn the oven off, and allow the shortbread to cool inside for one hour.
