1 pkg. Yellow cake mix

 1 egg, slightly beaten

1/3 cup butter

Cheese Filling:

1 cup ricotta cheese

2 eggs

¼ cup sugar

2 tbsp. Cornstarch

1 tsp vanilla

1 (29 oz.) can pear slices, drained

2 tbsp. Flour

¼ tsp. Cinnamon

Preheat oven to 350 deg.  Grease and flour 10 inch springform pan.  In a bowl, combine cake mix and egg.  Stir until blended.  Use a pastry blender and cut in the butter until the mixture resembles coarse crumbs.  Reserve 1/3 cup of crumbs for the topping.  Press remaining crumbs on to bottom and one inch up side of the prepared pan. Make filling in a bowl by combining the cheese, eggs, sugar, cornstarch and vanilla.  Pour filling into the pan.  Cut each pear slice into 3 more slices and arrange the slices over the filling.  To reserved crumbs, add flour and cinnamon and toss with a fork.  Sprinkle crumb mixture over the filling and pears.  Bake 60 - 65 minutes.  Cool in pan and then remove side of pan.  Cool, refrigerate until ready to serve.
