This is so fast and easy. I threw this together for many a church potluck.
yellow cake mix
cruched pieapple (20 ounce) undrained
cherry pie filling (21 ounce)
butter cut in thin slices
1Dump undrained pineapple into greased 13x9x2 inch pan, spread evenly. Dump pie filling on top and spread evenly.
2Dump dry cake mix onto cherry layer; spread evenly. Sprinkle pecans over cake mix. Put sliced butter on top.
3Bake at 350 for 48 to 53 minutes. Serve warm or cooled.
4My husband doesn't like cherry that well so I would some times substitute blueberry pie filling. And some times I would put cherry on half and blueberry on the other half. Use whats in your cabinet or your families favorite.
