Preheat oven to 350 degrees F.
Roll cookie dough very thin.
Line tiny tartlet molds with the cookie dough.
Cover the bottom of each tartlet mold with 1/2 teaspoon apricot preserves.
In a mixing bowl, cream the butter and sugar until light in color. Beat in the egg yolks one at the time. Stir in almond powder, Kirsch, and cornstarch.
Spoon the mixture into the tartlet shells until half filled. Bake for about 20 minutes or until tartlets are golden brown. Glaze.
