Step 1

Heat oven to 450°F. Make and bake pie crust as directed on box for One-Crust Baked Shell in ungreased 9-inch pie plate. Cool on cooling rack, 20 minutes.

Step 2

In 1-quart heavy saucepan, mix Fudge Layer and Sauce ingredients. Cook over medium-low heat, stirring constantly, until chips are melted. Remove from heat; stir until smooth. Reserve 2 tablespoons fudge mixture in small microwavable bowl for drizzle; cover and refrigerate until needed. Spread remaining mixture in bottom of cooled baked pie shell. Refrigerate 10 minutes.

Step 3

Meanwhile, in 4-quart saucepan, cook milk and pudding mix over medium heat 10 to 14 minutes or until mixture comes to a full boil, stirring constantly. Remove from heat. Add 1/2 cup chocolate chips; stir until melted and smooth. Let stand 5 minutes.

Step 4

Pour chocolate pudding mixture on top of fudge layer; spread smooth. Cover filling with plastic wrap. Refrigerate at least 3 hours until set.

Step 5

When ready to serve, remove plastic wrap from filling. In chilled medium bowl, beat whipping cream until soft peaks form; add marshmallow crème, and beat until blended and smooth. Spread on top of pudding layer. Remove reserved fudge mixture from refrigerator; uncover and microwave on High 15 to 20 seconds or until thin enough to drizzle. Drizzle over top of pie. Sprinkle marshmallow bits and crushed candies on top. Cut into wedges to serve. Store loosely covered in refrigerator.
