1 pkg. white cake mix
1 1/4 c. Quaker rolled oats
1/2 c. butter, softened
1 egg
1 (21 oz.) can cherry pie filling
1/2 c. nuts, chopped (optional)
1/4 c. brown sugar, firmly packed

Heat oven to 350 degrees. Grease 13 x 9-inch pan. In large bowl, combine cake mix, 6 tablespoons butter and 1 cup Quaker oats. Mix until crumbly. Serve 1 cup crumbs for topping. To remaining crumbs, add 1 egg; mix until well blended. Press into pan. Pour pie filling over crust; spread to cover.

To reserved crumbs, in a large bowl, add remaining 1/4 cup rolled oats, 2 tablespoons butter, nuts and brown sugar. Beat until thoroughly mixed. Sprinkle over cherry mixture. Bake for 30 to 35 minutes, or until golden brown. Cool completely. Makes 24 servings.

I use any flavor pie filling - doesn't have to be cherry.
