How to Make It
Beat butter and cream cheese at medium speed with an electric mixer for 2 minutes or until creamy; gradually add sugar, beating until mixture is light and fluffy. Add eggs, 1 at a time, beating until combined. Add vanilla extract, and beat just until blended.
Combine flour and salt in a small bowl; gradually add to butter mixture, beating at low speed just until blended after each addition. Pour batter into a greased (with shortening) and floured 10-inch tube pan.
Bake at 300° for 1 hour and 25 to 30 minutes or until a wooden pick inserted in center comes out clean. Cool cake pan on a wire rack 10 to 15 minutes; remove from pan, and let cool completely on wire rack (about 1 hour).
