1-1/4 cups vegetable oil
1 teaspoon vanilla extract
2-1/2 cups all-purpose flour
2 teaspoons baking powder
1 teaspoon baking soda
1 teaspoon salt
1 teaspoon ground cinnamon
4 medium tart apples, peeled and chopped (4 cups)
1 package (11 ounces) butterscotch chips
In a large bowl, beat the sugar, oil, eggs and vanilla until well blended. Combine the flour, baking powder, baking soda, salt and cinnamon; gradually add to egg mixture until blended. Stir in apples. In another bowl, pour the butterscotch chips in with 1-2 tbsp flour; gently mix with a spoon and then pour this into the main batter.
Pour into an ungreased 13-in. x 9-in. baking dish. Bake at 325° for 40-45 minutes or until a toothpick inserted near the center comes out clean. Cool on a wire rack and sprinkle with powdered sugar all over.
Serve with barely-sweetened whipped cream.
