3 cups all-purpose flour
3 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 cup cold butter, cubed
1 cup vanilla yogurt
1/2 teaspoon vanilla extract
2 teaspoons milk
In a large bowl, combine the flour, baking powder, baking soda and salt; cut in butter until the mixture resembles coarse crumbs. Stir in the egg, yogurt and vanilla just until combined. Turn onto a floured surface; knead 6-8 times.
Roll into a 9-in. circle; cut into eight wedges. Place on an ungreased baking sheet. Brush tops with milk; sprinkle with sugar.
Bake at 425° for 12-15 minutes or until golden brown. Serve warm. Yield: 8 servings.
