How to Make It
Grease bottoms of 3 (8-inch) round cake pans; line with wax paper. Grease and flour wax paper and sides of pans; set pans aside.
Cook first 3 ingredients in a saucepan over low heat, stirring constantly, 3 to 5 minutes or until butter melts and mixture is smooth; remove from heat, and let cool.
Beat buttermilk and next 3 ingredients at medium speed with an electric mixer until smooth. Add butter mixture to buttermilk mixture, beating until blended. Combine sugar, flour, and salt; gradually add to buttermilk mixture, beating until blended. (Batter will be thin.) Pour batter evenly into prepared pans.
Bake at 350° for 25 to 28 minutes or until a wooden pick inserted into centers comes out clean. Cool in pans on wire racks 10 minutes. Remove from pans, and cool completely on wire racks. (Cake layers will appear thin.)
Spread about 1/2 cup Chocolate Ganache between each cake layer; spread remaining Chocolate Ganache on sides of cake. (Do not frost top of cake.) Chill cake 30 minutes. Pour warm Praline Frosting slowly over top of cake, spreading to edges. (Cover and let stand up to 24 hours, if desired.)
Pierce about 25 holes in top of cake using a wooden or metal skewer. Pour warm Bourbon Glaze over cake.
