Preheat oven to 350℉
Prepare an 8" round cake pan (or 9" pie plate) by spraying with baking spray. Cut a circle of parchment paper to fit in the bottom of the pan.
Place sugar, softened butter and salt in the bowl of a stand mixer fitted with the paddle attachment (a hand mixer may also be used).
Begin mixing the sugar, salt and butter on medium speed. Continue to mix until light and fluffy (2 - 4 minutes), scraping the side and bottom of the bowl as needed.
Add vanilla bean paste and mix until incorporated.
Add flour to the mixing bowl and mix on low speed until just incorporated. The mixture will look crumbly but should hold together when squeezed with your hands.
Pour all of the dough into the prepared pan. Using your palms, a dough tamper or a flat-bottomed drinking glass, press lightly on the dough so it is evenly distributed on the bottom of the pan.
Using a sharp knife, score the top of the dough lightly by making 4 lines running across the diameter of the pan (resulting in 8 wedges).
Using a dinner fork, mark impressions in the dough on the outermost edge.
Bake 22 - 25 minutes. The top will be a light brown and the edges a bit darker.
Allow the pan to cool for 10 minutes on a rack. Carefully turn the pan upside down and release the cookie disk.
Flip the cookie disk over and, using a sharp knife or bench scraper, cut through the scored lines you created before baking. Place wedges on a rack and allow to cool completely before serving.
