1 package (regular size) yellow or white cake mix
1/4 Cup cooking oil
1/2 Cup water
1 Can pie filling (20-23 oz. size)
Pour oil into a 13 x 9 x 2 inch pan; tilt pan to cover bottom. Put cake mix, eggs and water into 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 creat a marbled effect. Bake at 350 degrees for 35 – 45 minutes (until toothpick (or a thin knife) inserted near center comes out clean) . Let cool a little bit before serving.
Suggestions for pie mix: cherry, apple, blueberry, peach
