How to Make It
Preheat oven to 300°F. Generously coat a 10-inch tube pan with shortening; dust with flour. Beat butter and cream cheese with a stand mixer fitted with a paddle attachment on medium speed until smooth, about 30 seconds. Gradually add sugar, beating until light and fluffy, about 5 minutes. Add eggs; beat until just blended, about 30 seconds. Add flour; beat until smooth, about 30 seconds. Stir in vanilla.
Pour batter into prepared tube pan. Bake in preheated oven until a wooden pick inserted in center comes out clean, about 1 hour, 45 minutes. Cool in pan 20 minutes. Remove from pan, and let cool completely on a wire rack, about 2 hours.
Because of the high sugar content of this cake, it will develop a delicious, crunchy crust on top, that may separate from the cake as it cools.
