Directions:

Beat egg yolks and sugar at medium speed with an electric mixer 3 to 4 minutes or until thick and pale. Add vanilla and salt, and beat 1 more minute. Beat egg whites until stiff peaks form. Fold into yolk mixture, alternating with flour (do not overmix).

Fit a pastry bag with a round tip with a 1/2-inch opening. Spoon batter into bag. Line 2 baking sheets with parchment paper; coat lightly with cooking spray. Pipe 3-1/2-inch long strips of batter onto paper, placing 3/4 inch apart. Sprinkle with powdered sugar. Bake at 300 F. for 18 to 20 minutes.
