Mother’s Walnut Cake

Directions

• Preheat oven to 350°. Cream butter, shortening and granulated sugar. Add eggs, one at a time, beating well after each addition. Combine flour, baking soda and salt; gradually add to creamed mixture alternately with buttermilk and vanilla. Beat on low speed just until combined. Stir in ground walnuts.
• Pour into three greased and floured 9-in. round pans. Bake until a toothpick inserted in the center comes out clean, 20-25 minutes. Cool 5 minutes; remove from pans to wire racks to cool completely.
• For frosting, beat cream cheese and butter. Add confectioners' sugar; mix well. Beat in vanilla until smooth. Spread frosting between layers and over the top and sides of cake. Sprinkle with walnuts. Refrigerate.
