Pineapple Upside Down Cake

This is a cake that my husband ask me to make him at Christmas. It was the first time I had ever made it and it was awesome.  The whole family loved it and wants it all the time now.

1/2 cup butter
1 1/2 cup brown sugar
1 20 oz can sliced pineapple
10 maraschino cherries
1 box of white cake mix
1 8 oz can of crushed pineapple

Melt butter in a skillet. Sprinkle brown sugar over butter. Evenly arrange pineapples around bottom of skillet. Place cherries in center of pineapples. Make cake per directions on box but use pineapple juice instead of water and add the crushed pineapple to batter. Pour mixture over the pineapples. Bake per cake box time and cool 10 minutes and turn on a plate. Cake is very pretty.
