Preparation
Preheat oven to 350°. In a small bowl, combine 1-1/2 cups cracker crumbs and butter. Press mixture into a greased 13x9-in. baking dish. Bake until lightly browned, about 10 minutes. Cool on a wire rack.
In a large saucepan, combine the sugar, cornstarch and rhubarb. Bring to a boil; cook and stir until thickened and rhubarb is tender, 2-3 minutes. Remove from the heat; stir in gelatin until dissolved. Cover and refrigerate until partially set, about 1 hour.
Spoon rhubarb mixture over crust. Combine whipped topping and marshmallows; spread over rhubarb mixture.
In a large bowl, whisk milk and pudding mix for 2 minutes. Let stand until soft set, about 2 minutes. Carefully spread over marshmallow topping (the dish will be full). Sprinkle with remaining cracker crumbs. Refrigerate for at least 2 hours before serving.
