Pineapple Upside Down Orange Cake

At a recent blood drive a gentleman and I started up a conversation about baking. His wife had called while he was waiting and it seems they had a family reunion the next day and there was a request for his Pineapple Upside Down Cake. His secret, the cake mix he uses. It sounded so good I made it the next day. It is yummy.!
NEED:
1 box of Duncan Hines Orange Cake mix.
1 cup light brown sugar, packed
1 stick (1/2 cup) margarine or butter
1 (14.5-ounce) can pineapple slices
Maraschino cherries
Mix the orange cake mix as directed on package, using juice from pineapple instead of water, add water to make up necessary amount called for, if needed.
Melt butter and brown sugar over low heat in a large 10-inch pan or iron skillet.( you can do this in 2 8 pans or in a 9 x 13 pan)
Place pineapple rings onto butter/brown sugar mixture in pan, and put cherries in rings. Pour cake batter on top.
Oven at at 350*F Bake for 1 hour. Let stand for 5 minutes and flip over onto a large cake plate

ENJOY!
