1 1/4 cups all-purpose flour
3 tablespoons confectioners' sugar
2 tablespoons granulated sugar
1/2 teaspoon salt
1 whole egg
2 egg whites
1 teaspoon vanilla extract
Vegetable oil, for frying
Confectioners' sugar
Ground cinnamon

Combine flour, 3 tablespoons confectioners' sugar, granulated sugar and salt in small bowl. Stir in whole egg, egg whites and vanilla extract with fork until mixture is crumbly. Form dough into ball; knead on lightly floured surface until smooth, about 5 minutes. Cover loosely; let stand about 30 minutes.

Heat 2 inches of oil to 375 degrees F in a heavy, large saucepan. Roll dough on floured surface to 12-inches square, about 1/8-inch thick. Cut into 12 one-inch strips; cut strips in half to form 24 (6 x 1-inch) strips. Tie each strip into a knot. Fry knots in oil, a few at a time, 3 to 4 minutes or until golden. Drain on paper towels.

Sprinkle with confectioners' sugar and cinnamon. Serve warm.
