This recipe came from a California bakery. They had been making lemon bars for several years and they had always sold well. During a trip to Europe they saw a pastry in a bakery called 'Lemon Lust'. They loved the name. When they returned to their own bakery, they renamed their lemon bars 'Lemon Lust'. Their sales tripled! The kind of marketing that I'm a sucker for! I've made these many times and can't imagine anything yummier!
1 cup (8 oz. ) cold butter
1/2 cup powdered sugar
1/4 tsp. salt
2 cups all-purpose flour
1/2 tsp baking powder
1/4 cup all-purpose flour
4 large eggs
2 cups granulated sugar
1/4 cup + 1 Tbsp. freshly squeezed lemon juice
2 Tbsp grated lemon zest (about two lemons)
Powdered sugar for dusting
Preheat oven to 350 degrees.
In food processor:
Cut the cold butter into 1" pieces--return to refrigerator
In the bowl of the food processor fitted with the metal chopping blade, place the powdered sugar, salt, and flour. Pulse until well blended. Add the chilled butter and toss with your hands to coat the pieces with flour. Process the mixture until it looks like fine meal, about 15 seconds. (Can be made in a bowl with a pastry cutter)
Transfer crust dough to a 15x10* inch glass baking pan and press firmly into the bottom. Place pan on center rack in a 350 degree oven and bake for 15 minutes.
While the crust bakes, make the filling. Combine the baking powder and flour. In a separate medium bowl, beat the eggs with a whisk until they are well mixed. Add the sugar and beat until it is fully incorporated. Add the baking powder and flour in small amounts, beating after each addition. Whisk in the lemon juice and zest.
Pour filling over hot crust and return to oven for 15-20 additional minutes or until filling has set and top is golden brown. Let bars cool in the pan on a wire rack. When completely cool, dust with powdered sugar.
*I don't have this size pan. I use a 9x13 and bake it for 5 minutes or so longer. The center will be slightly jiggly. And yes, calling them 'Lemon Lust' does make them taste better.
