Classic Shortbread 101 Recipes

Steps:

• Position an oven rack in the center of the oven and preheat to 325 degrees F. Butter a 9-by-12-1/2-inch jelly roll pan and line it with parchment, then butter the paper.
• Whisk together the flour, cornstarch and salt in a bowl. Beat the butter and sugar with an electric mixer on medium speed until light and fluffy, 5 to 7 minutes. Slowly add the flour mixture and beat on low until the dough is just combined; do not overwork.
• Transfer the dough to the prepared pan, spreading it out as evenly as possible with a spatula. Cover with plastic wrap, then use your hands to press and flatten the dough into a smooth even layer. Remove the plastic and cut the dough with a sharp knife into approximately 1-by-3-inch bars. Use a fork to prick a decorative pattern into the tops.
• Bake, rotating the pan from front to back halfway through, until golden, 60 to 70 minutes. Let stand for 5 minutes in the pan, then re-cut the bars along the previous cuts. Carefully lift the bars off the parchment with a small spatula and transfer them to a wire rack to cool completely. Store the cookies in an airtight container for up to 5 days.

Steps:

• Preheat oven to 300 degrees. Sift together flour and salt into a medium bowl. Beat butter with a mixer on medium-high speed until fluffy, 3 to 5 minutes, scraping down sides of bowl with a rubber spatula as needed. Add sugar gradually, beating between additions; continue to beat until mixture is very pale, about 2 minutes total. Reduce speed to low, and add flour mixture; beat until just combined.
• Press dough evenly into a parchment-lined 9-by-13-inch rimmed baking sheet; refrigerate until firm, about 20 minutes. Cut dough in eighths lengthwise, then quarters crosswise, making 32 rectangles. Evenly pierce all over with a skewer.
• Bake until shortbread is firm in center and golden brown, 50 minutes to 1 hour. Transfer pan to a wire rack; immediately recut rectangles with a paring knife. Let shortbread cool completely in pan.

Steps:

• Beat 2 sticks butter, 1/4 cup granulated sugar and 1/2 cup confectioners' sugar until fluffy. Whisk 2 cups flour and 1 teaspoon salt, then stir into the butter mixture. Press into a buttered 8-inch square or 9-inch round tart pan. Score into wedges, strips, squares or diamonds with a fork, then chill 30 minutes. Bake about 1 hour at 300 degrees. Cool, then slice along the scored lines.
