Steps:

• Preheat oven to 350°. In a food processor, combine the flour, confectioners' sugar, and lemon and orange zest. Add butter; cover and process until mixture forms a ball. , Pat into a greased 13x9-in. baking pan.

In a small bowl, combine topping ingredients. Spread over filling. , Bake until topping is set, 7-9 minutes longer. Cool on a wire rack. Refrigerate overnight. Cut into bars just before serving. Store in the refrigerator.

Steps:

• Heat oven to 350°F Line 13x9-inch pan with foil so that foil hangs over edges. Cut 13x9-inch piece of parchment paper; place over foil in bottom of pan.
• Place 1 cup macadamia nuts and 3/4 cup sugar in food processor; pulse until nuts are finely ground. Add flour, butter and lemon peel; pulse until mixture is blended (dough will not form). Spread mixture in pan; press evenly to form crust. Prick dough all over with fork. Bake 20 to 25 minutes or until pale brown. Cool completely.
• In heavy medium saucepan, whisk together egg yolks and 6 tablespoons sugar; whisk in lemon juice. Cook over medium heat 4 to 5 minutes or until thickened and temperature reaches 160°F Remove from heat; whisk in 1/4 cup butter and 1 teaspoon lemon peel. Place in small bowl; press plastic wrap directly on surface. Cool to room temperature; spread over crust. Sprinkle with 1/4 cup macadamia nuts. Refrigerate 1 hour or until firm.
• Remove bars by lifting foil ends. Slide bars with parchment paper liner onto cutting board. Cut into 36 pieces. Store in refrigerator.

Steps:

• Heat oven to 325 degrees and line a 9-by-9-inch baking pan with enough parchment to hang over two of the sides (to be used as handles later to lift the bars out of the pan).
• To make the shortbread base, pulse together the flour, granulated sugar, confectioners' sugar, lemon zest and salt in a food processor, or whisk together in a large bowl. Add butter and pulse (or use two knives or your fingers) to cut the butter into the flour until a crumbly dough forms. Press dough into prepared pan and bake until shortbread is pale golden all over, 30 to 35 minutes.
• While the shortbread is baking, prepare the lemon curd: Grate 1/2 tablespoon zest from lemons and set aside. Squeeze lemons to yield 3/4 cup juice.
• In a small saucepan, whisk together lemon juice, sugar, eggs and yolks, cornstarch and fine sea salt over medium heat until boiling and thickened, 2 to 5 minutes. Make sure mixture comes to a boil and stays there for 30 seconds or so; you should see it thicken up before you take it off the heat. But once it boils do not cook for longer than 1 minute or you risk the curd thinning out again. Remove from heat and strain into a bowl. Whisk in butter, olive oil and lemon zest.
• When the shortbread is ready, take it out of the oven and carefully pour the lemon curd onto the shortbread base; return the pan to the oven. Bake until topping is just set, 10 to 15 minutes more. Allow to cool to room temperature, then refrigerate until cold before cutting into bars. Sprinkle with confectioners' sugar and flaky sea salt right before serving.

Steps:

• Preheat oven to 300 degrees, with rack in upper third. Sift flour and salt into a bowl; set aside. Put butter into the bowl of an electric mixer fitted with the paddle attachment. Mix on medium-high speed until fluffy, 3 to 5 minutes, scraping down sides of bowl. Gradually add sugar; beat until pale and fluffy, about 2 minutes. Mix in lemon zest and juice.
• Reduce speed to low. Add flour mixture all at once; mix until just combined.
• Halve dough, and shape into disks. Wrap each in plastic, and refrigerate 1 hour.
• Working with 1 disk at a time, roll out dough on a lightly floured surface to 1/4 inch thick. Cut out rounds with a 2-inch fluted cutter. Space 1 inch apart on baking sheets lined with parchment. Refrigerate 30 minutes.
• Bake until pale golden brown, 22 to 25 minutes. Transfer cookies to a wire rack; let cool completely. Dust with confectioners' sugar.

Steps:

• For crust:
• Preheat oven to 350°F. Lightly coat 13x9x2-inch metal baking pan with nonstick spray. Blend flour, sugar and salt in processor to combine. Cut in butter, using on/off turns, until mixture resembles coarse meal. Add egg yolks and blend until moist clumps form. Press mixture onto bottom of prepared pan. Bake until just beginning to turn golden brown around edges, about 10 minutes. Remove crust from oven; reduce temperature to 325°F.
• Meanwhile, prepare lemon filling:
• Whisk eggs and sugar in large bowl to blend. Whisk flour and baking powder in medium bowl to blend. Add flour mixture to egg mixture, whisking to blend. Whisk in lemon juice and peel. Immediately pour lemon filling over hot crust; bake until filling is set, about 30 minutes. Maintain oven temperature.
• For streusel:
• Blend flour, 1/2 cup sugar and salt in processor to combine. Cut in butter, using on/off turns, until mixture resembles coarse meal.
• Sprinkle topping over hot lemon bars; continue to bake until just golden, about 25 minutes longer. Cool completely. Sprinkle powdered sugar over. Cut into bars. (Can be made 2 days ahead. Store in airtight container at room temperature.)
