Lemon Whipped Cream Torte

Directions

1. In a bowl, cream butter, shortening and 1 cup sugar. Add lemon zest and vanilla; mix well. Combine the flour, baking powder and salt. Gradually add to creamed mixture alternately with milk, mixing well after each addition; set aside.
2. Beat egg whites, gradually adding remaining sugar until soft peaks form and sugar is dissolved. Fold into the creamed mixture. Pour into three greased and waxed paper-lined 9-in. round baking pans. Bake at 350° for 15-20 minutes or until a toothpick inserted in the center comes out clean. Cool in pans for 10 minutes before removing to wire racks to cool completely.
3. For filling, combine sugar and flour in a saucepan. Gradually add milk; cook and stir until thickened and bubbly. Cook and stir 2 minutes more. Remove from heat. Gradually stir a little of the hot filling into the yolks; return all to the pan. Bring to a gentle boil. Cook and stir 2 minutes more. Remove from heat. Stir in lemon juice, vanilla and zest. Cover and cool. Fold in the cream. Spread between each layer and on top of cake. Cover and chill.
