Creamy Rhubarb Dessert

Directions

1. In a large saucepan, combine sugar and cornstarch; stir in water until smooth. Add rhubarb; cook and stir until tender, about 10 minutes. Cool.
2. Meanwhile, for crust, combine the flour, sugar and nuts in a large bowl. Cut in butter until mixture resembles coarse crumbs. Press into an ungreased 13-in. x 9-in. baking dish. Bake at 350° for 20 minutes or until lightly browned. Cool on a wire rack.
3. Pour cooled filling over crust. In a bowl, beat cream until stiff peaks form; fold in marshmallows. Spread over filling. In a bowl, whisk pudding mix and milk for 2 minutes; let stand for 5 minutes or until soft-set. Spread over marshmallow topping. If desired, sprinkle with nuts. Cover and chill for several hours.
