1 pkg. white cake mix
2 eggs
1/4 c. cooking oil
1/2 c. water
1 (20-23 oz.) can pineapple pie filling

Preheat oven to 350 degrees. Pour oil into 13"x9"x2" pan; tilt the pan to cover bottom. Put cake mix, eggs and water into the pan. Stir with a fork or spoon until blended, about 2 minutes. Scrape sides and spread batter evenly in pan. Spoon pie filling onto batter; use a fork to fold into batter just enough to create a marbeled effect. Bake at 350 degrees for 40 to 50 minutes until toothpick comes out clean. Frost with Double Boiler frosting and top with shredded coconut.
