1 cup white sugar
2 eggs
1 1/2 teaspoons vanilla extract
1 3/4 cups all-purpose flour
2 teaspoons baking powder
1/2 teaspoon salt
1/2 cup milk
1/4 cup confectioners' sugar for dusting
Preheat oven to 350 degrees. Grease and flour a 9-inch round pan. In a medium bowl, cream together the butter and sugar until light and fluffy. Beat in the eggs, one at a time then stir in the vanilla. Combine the flour, baking powder and salt; stir into the batter alternately with the milk. If the batter is too stiff, a tablespoon or two of milk may be added. Spread the batter evenly into the prepared pan.
Bake for 30 to 35 minutes in the preheated oven, until a toothpick inserted into the center comes out clean. Cool in pan on a wire rack, then turn out onto a serving plate. Dust with confectioners' sugar right before serving.
