Pre-heat oven to 375F (190C). Line 1-2 cookie sheets with parchment paper.
In a medium bowl sift together the flour, corn starch, baking powder and salt. Set aside.
In a mixing bowl beat the egg yolks, sugar and vanilla until light about 10-12 minutes.
In a medium bowl beat the egg whites until stiff.
Fold the egg whites into the yolks in three additions, make sure each addition is completely added before adding more, continue until all the whites are added and it's completely combined.
Fold the sifted dry ingredients into the egg mixture in three additions, make sure each addition is added before adding more, gently fold until completely combined. Place the batter into a pastry bag with medium or large tip and make sticks about 1 1/2 - 2 inches (2 - 2 ½ cm) long.
Sprinkle each cookie with either a little powdered sugar or granulated sugar and bake for approximately 10-12 minutes or until golden. Let the cookies cool and then dust with powdered sugar before serving or using in your favourite Italian dessert. Enjoy!
I made 6 large cookies and 8 medium. The recipe can also be doubled.
