Pizza Crust:
1 cup warm (105F) water
2 cups flour
1−1/2 tablespoons vegetable oil
3/4 cup cake flour
1 teaspoon salt
1/4 teaspoon active dry yeast
Fruit Filling:
1 − 21 oz. can pie filling (cherry, blueberry, or apple)
Crumb Topping:
1/2 cup flour
1/2 cup brown sugar
1/2 cup quick oats
1/2 cup firm butter or margarine
1 teaspoon cinnamon
Vanilla Glaze:
2 cups powdered sugar
3 tablespoon Milk
1 tablespoon Melted margarine or butter
1 teaspoon vanilla
Combine yeast and warm water and let proof for 3 minutes. Add to other crust ingredients in a large bowl and knead for 10 minutes. Cover with plastic wrap, and allow to rise for about 12 hours.
Preheat oven to 500F. Roll the dough on a floured surface until it is about the diameter for your 16 inch pizza pan. Place in pan and form the dough to the edge. Brush with vegetable oil and prick with fork. Prebake for 3 minutes. Remove from the oven and spread with pie filling. Mix crumb topping ingredients with a fork or pastry blender. Spoon over pie filling. Return pizza to the oven and continue to bake for 10−15 minutes or until crust is light golden brown. Remove and drizzle with vanilla glaze.
