1 pkg. cake mix (any flavor)
1/4 c. oil
2 eggs
1/2 c. water
1 sm. can pie filling (any fruit)

Pour oil in 13 x 9 inch pan; tilt pan to cover bottom. Put cake mix, eggs, and water into pan. Stir with fork until blended. 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 marbled effect. Bake at 350 degrees for 35 to 40 minutes. Sprinkle cake with powdered sugar. Cool and serve.
