COOKIE DOUGH:
1.5 cups all-purpose flour
1/3 cup cornstarch
1/2 teaspoon baking powder
12 tablespoons (1.5 sticks) unsalted butter, softened
2/3 cup confectioners' sugar
1 teaspoon vanilla extract

LEMON FILLING:
6 tablespoons (3/4 stick) unsalted butter, softened
1 cup confectioners' sugar
1 tablespoon lemon juice
2 cookie sheets or jelly roll pans covered with parchment or foil

DIRECTIONS:
1. Preheat oven to 350F.
2. Combine flour, cornstarch, and baking powder in a bowl; stir well to mix.
3. In the bowl of a standing electric mixer fitted with the paddle attachment, beat together the butter and confectioners' sugar on medium speed until soft and light, about 3 or 4 minutes. Beat in the vanilla. Lower the speed and beat in flour mixture.
4. Remove the bowl from the mixer and finish mixing the dough with a large rubber spatula.
5. Use a teaspoon measuring spoon or a small ice cream scoop to scoop up a piece of the dough. Roll each piece into a ball between the palms of your hands and place on the prepared pans, leaving about 2 inches around each cookie in all directions. press each cookie with the back of a fork dipped in flour to flatten the cookies slightly, and make a crisscross pattern.
6. Bake the cookies for about 15 minutes, or until they are a uniform light golden color. cool the cookies on the pans on racks.
7. While the cookie are cooling, prepare the filling. in the bowl of an electric mixer fitted with the paddle attachment, beat together the butter and confectioners' sugar until very light, about 5 minutes. Beat in the lemon juice a little at a time, then continue beating until very light and smooth.
8. Turn half the cookies upside down so that the flat bottom side is uppermost. pipe or spoon about 1/2 teaspoon of the filling on each. Cover with another cookie, bottom to bottom.
9. Store the finished cookies between sheets of parchment or wax paper in a tin or plastic container with a tight-fitting cover.
