This is a vintage recipe from Bacardi. We only make this during the holiday season.

If using yellow cake mix with pudding already in the mix, omit the instant pudding, using 3 eggs instead of 4 and 1/3 cup oil instead of 1/2 cup.
18.25 ounce boxes of cake mix have been replaced by 16.5 ounce and 15.25 ounce boxes. To compensate for the volume loss in a 16 ounce box, whisk 6 tablespoons all-purpose flour into the dry cake mix before proceeding with the recipe. To compensate for the volume loss in a 15.25 ounce box, add 1/2 cup + 3 tablespoons all-purpose flour and 1/4 teaspoon baking powder.
