Here's a recipe for a dump cake I saw on PBS, contributed by one of the viewers who had been invited to the studio to make the cake in front of the camera during one of the pledge periods. They all said it was really good, and since then, it supposedly has become one of their most requested recipes.
Peaches and Cream
1 large can crushed pineapple
1 bag frozen peaches
1 package white cake mix (2-layer size)
1 bag frozen peaches (second bag)
1 cup raisins
1 cup pecans (optional)
1/2 cup brown sugar
1/2 cup butter, melted
Layer all items in order given in a 9 x 13 cake pan by sprinkling each ingredient evenly over surface. Pour melted butter over the top.
Bake at 350 degrees for about 45-55 minutes. Serve warm with vanilla ice cream.
