1 pkg. white or yellow cake mix
1 (21 oz.) cherry pie filling (or any fruit filling)
1/4 c. oil
2 eggs
1/2 c. water

Preheat oven to 350 degrees. Pour oil into 13 x 9 x 2 inch pan, tilt pan to cover oil on bottom. Put dry cake mix, eggs and water into pan. Stir with a fork or spatula until blended (about 2 minutes). Scrape sides and spread batter evenly in pan. Spoon pie filling into batter. Fold into batter. Just enough to make a marble effect. Bake 35-45 minutes.
