Sinful Brownie Pie

1 box brownie mix
1/2 cup chopped walnuts
1/2 cup chopped chocolate chips
1/2 cup miniature marshmallows
1 small box chocolate pudding
2 cups Cool Whip

Prepare brownie mix as directed on the box. Use 9-inch round pie plate to bake the brownies.

Prepare chocolate pudding as the box directs for a pie. Set aside 1 cup of the Cool Whip and mix remaining 1 cup Cool Whip with prepared chocolate pudding. Fold in miniature marshmallows, all chocolate chips (except for approximately 2 tablespoons) and all chopped walnuts (except for approximately 2 tablespoons).

After the brownies are cool, spread chocolate pudding-Cool Whip mixture on top as if you were icing a cake. Sprinkle remaining chocolate chips and walnuts to garnish. Refrigerate for approximately 1 hour.

Serve with remaining Cool Whip.
