For the cookies:
1 cup (2 sticks) sweet butter
1/2 cup confectioners' sugar
1/2 teaspoon vanilla extract
Grated zest of 3 lemons (6 to 9 teaspoons)
1 1/2 cups all-purpose flour
3 tablespoons cornstarch
For the filling:
4 tablespoons (1 1/2 stick) sweet butter
1 cup confectioners' sugar
Grated zest of 2 lemons (4 to 6 teaspoons)
Juice of 1/2 lemon (2 teaspoons)
For dipping:
6 oz. bittersweet chocolate, melted
Preheat the oven to 350 degrees. Beat the butter, confectioners' sugar, vanilla extract, and lemon zest together until light and fluffy. Sift the flour and cornstarch together and stir into the creamed mixture. Using a 1/2 inch fluted nozzle and piping bagkk pipe the mixture into 2 inch fingers arranged 1 1/2 inches apart on a non-stick baking sheet. Bake the cookies for 12 minutes. Allow them to firm up before transferring them to a wire rack to cool.
To make the filling, beat the butter and confectioners' sugar with the lemon zest and juice until light and fluffy. Spread the filling onto the flat side of one cookie, then put another cookie on top and sandwich together. Half-dip the fingers (on a diagonal) into melted bittersweet chocolate. Place on parchment until the chocolate sets.
