Preheat Oven to 350 degrees. Spray a bundt pan with nonstick cooking spray. You can also use a 13 x 9 cake pan.
Layer a can and half of the crushed pineapple on the bottom of the pan. I did not use the entire two cans. I thought that was too much. Sprinkle yellow cake mix on top. Cut up a stick of butter pats and layer on top of cake. Sprinkle coconut on top.
Bake approx. 40 minutes or until coconut is toasty. It will be done. Ovens vary in temp so keep an eye on it. You can poke it with a tooth pick to see if it is cooked through. Let cool for 30 minutes or so and serve. Serve with ice cream or cool whip:) Enjoy!
