Preheat oven to 350°F. Grease a Bundt pan well with Baker’s Pam.
In a small bowl, whisk the melted butter with the brown sugar. Pour this mixture evenly into the bottom of the pan.
Arrange pineapple slices over the sugar mixture and place a maraschino cherry in the center of each slice.
In a mixing bowl, combine the cake mix, eggs, and 1 cup of pineapple juice (add water as needed to make 1 full cup). Whisk until smooth.
Pour the batter evenly over the pineapples and cherries.
Bake for 25 minutes, or until a toothpick inserted in the center comes out clean.
Let the cake cool for 5 minutes. Place a serving plate over the Bundt pan, flip carefully, and lift the pan away.
Slice, serve, and enjoy!
