1 stick butter
2 cans sliced peaches (with juice)
1 box yellow cake mix

Melt butter in a 9 x 13 inch glass dish or cake pan. Add peaches with juice and mix. (Place all peaches on their sides.) Sprinkle cake mix over top. (Pat down some, so it absorbs liquid but do not mix.) Bake at 350 degrees until brown on top, about 40 to 45 minutes.
