Follow these simple steps to create your own batch of irresistible shortbread cookies:

1. Preheat the Oven: Start by preheating your oven to 325°F (165°C) and line a baking sheet with parchment paper.
2. Cream the Butter: In a mixing bowl, cream together the softened butter and granulated sugar until the mixture is light and fluffy.
3. Add Vanilla: If using, stir in the vanilla extract for added flavor.
4. Mix Dry Ingredients: In a separate bowl, whisk together the flour and salt.
5. Combine Mixtures: Gradually add the dry mixture to the creamed butter and sugar, mixing until just combined.
6. Form the Dough: Turn the dough onto a lightly floured surface and knead gently until it holds together.
7. Shape the Cookies: Roll the dough into a log about 1-2 inches thick, or press it into a square or rectangular pan for cut-out cookies.
8. Chill: Wrap the dough in plastic wrap and chill in the refrigerator for at least 30 minutes to firm up.
9. Slice and Bake: If you’ve shaped the dough into a log, slice into ¼-inch thick rounds. If pressed in a pan, cut into squares or rectangles. Place them on the prepared baking sheet and bake for 20-30 minutes or until lightly golden.
10. Cool: Once baked, remove from the oven and let the cookies cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
11. Dust (Optional): When cooled, dust with powdered sugar if desired for a lovely finishing touch.
