Preheat oven to 350 degrees F. Make cake batter as directed replacing as much of the water as you can with pineapple juice. Spray sides of 2 (9 inch) cake pans with Pam.
Melt 1/4 cup butter in 1 (9 inch) cake pan over low heat. Turn off heat. Add 1 cup brown sugar over butter spreading evenly. Place sliced pineapple rings over brown sugar as closely as possible. Add half of maraschino cherries in-between and in the center of pineapples. Pour cake batter over cherries.
Repeat steps with remaining ingredients filling cake pans equally.
