# What You’ll Need:
→ Base Dough
01 - 1 cup unsalted butter, softened
02 - ½ cup granulated sugar
03 - 2 cups all-purpose flour
04 - ¼ cup cornstarch
05 - ¼ teaspoon fine sea salt
# How-To Steps:
01 - Preheat the oven to 325°F. Line a baking sheet with parchment paper.
02 - In a large bowl, beat the butter and sugar together until the mixture is light and fluffy.
03 - Sift the all-purpose flour, cornstarch, and sea salt into the butter mixture. Stir gently until a soft dough forms, taking care not to overwork it.
04 - Press the dough evenly into an 8x8-inch baking pan or shape it into a rectangle about ½ inch thick on the lined baking sheet.
05 - Use a sharp knife to score the dough into wedges or finger shapes, then lightly prick each piece with a fork to prevent rising during baking.
06 - Bake for 22 to 25 minutes until the edges turn pale golden. Avoid browning the cookies.
07 - Allow the shortbread to cool in the pan for 5 minutes before cutting along the scored lines. Transfer to a rack to cool completely before serving.
