                    Key lime cheesecake stands in as frosting between the layers on this decadent cake. It's important to use 10-inch cakepans to make this one-of-a-kind recipe. Ingredients: 
                    
                        
                                                1 (18 1/4 ounce) package white cake mix  |  
                                                1 cup buttermilk  |  
                                                1/4 cup vegetable oil  |  
                                                3 large eggs  |  
                                                1/3 cup cream of coconut  |  
                                                2 cups sweetened flaked coconut, divided  |  
                                                1 cup sugar  |  
                                                1/4 cup cornstarch  |  
                                                4 (8 ounce) packages cream cheese, softened  |  
                                                3 large eggs  |  
                                                1 (8 ounce) container sour cream  |  
                                                1/2 cup key lime juice  |  
                                                1 (16 ounce) container ready-to-spread vanilla frosting  |  
                                                
                     
                    Directions: 
                    
                        
                            
                                1. Combine first 5 ingredients in a mixing bowl; beat at medium speed with an electric mixer 4 minutes. Stir in 1 cup coconut. Divide batter evenly between 2 lightly greased 10-inch round cakepans. 2. Bake at 350° for 25 minutes or until a wooden pick inserted in center comes out clean. Cool in pans 10 minutes on wire racks; remove from pans, and cool completely on wire racks. 3. Split cake layers in half horizontally to make 4 layers. Crumble 1 cake layer into fine crumbs. Toss cake crumbs with remaining 1 cup coconut; spread on a baking sheet. Bake at 350° for 10 minutes or until coconut is toasted. Set aside. 4. Combine sugar and cornstarch. Beat cream cheese at high speed with an electric mixer until creamy; gradually add sugar mixture, mixing well. Add eggs, 1 at a time, beating after each addition. Stir in sour cream and lime juice, blending well. 5. Place 1 cake layer, cut side up, in the bottom of a lightly greased 10-inch springform pan. Spoon 1/3 cheesecake batter over cake layer; repeat procedure with remaining cake layers and cheesecake batter. (See tip.). 6. Bake at 325° for 1 hour or until set. Cool completely in pan on a wire rack. Cover and chill at least 4 hours. 7. Run a knife around the edge of pan, releasing sides. Spread frosting over top and sides of cake. Pat reserved crumb mixture generously around sides and top of cake. Chill at least 1 hour before serving. Store in refrigerator. 8. Tip: It may be necessary to use a foil collar around the springform pan to hold the cake and cheesecake mixture once it's layered in the springform pan. Cut a piece of aluminum foil long enough to fit around the 10-inch springform pan, allowing 1-inch overlap; starting from 1 long side, fold foil into thirds. Lightly grease 1 side of foil. Wrap foil around outside of pan, greased side against pan, allowing it to extend to 1 1/2 inches above rim to form a collar; secure with string or masking tape. Bake as directed.                              |
