Preheat oven 350 degrees.
In a bowl combine vanilla cake mix, vegetable oil, eggs, orange juice, rum, and 1/4 cup pomegranates. Mix well.
Divide the batter between two nine-inch cake pans. Bake for about 25 minutes or until you insert a toothpick and it comes out clean.
Let the cakes cool completely. Once cooled, cover the tops and the cakes with rum frosting. Put one nine-inch frosted cake on top of the other. Then cover the sides of the cake until the whole cake has been covered.
Garnish the top of the cake with remaining pomegranates and HoneyBell slices.
