Sift flour once, measure, add baking powder, and sift together three times. Cream butter thoroughly, add sugar gradually, and cream together until light and fluffy. Add flour, alternately with milk, a small amount at a time. Beat after each addition until smooth. Add lemon extract. Fold in egg whites; bake in two greased 9-inch layer pans in moderate oven (375°F.) 25 to 30 minutes. Spread Snowy Lemon Frosting ([page 17]) between layers and on top and sides of cake.
