   Preheat oven to 325°. Beat butter at medium speed with an electric mixer until creamy; gradually add sugar, beating well. Combine flour, baking powder, and salt; add to butter mixture alternately with milk, beginning and ending with flour mixture. Beat at low speed just until blended after each addition.

   Bake at 325° for 25 minutes or until a wooden pick inserted in center comes out clean. Cool in pans on wire racks 10 minutes. Remove from pans to wire racks, and cool 1 hour or until completely cool.
4. 4
   Spread Lane Cake Filling between layers and on top of cake. Prepare 7-Minute Frosting; spread onto sides of cake.
