Frozen Milky Way Mousse Pie - with Nutella!

This recipe was in my Woman's World magazine, and it is so incredibly delicious!  And very bad for you.  But worth it for a splurge here and there (I made it for Paul on our anniversary).

1 can sweetened condensed milk

1/2 cup Nutella

2 1/3 cups heavy cream

5 fun-size Milky Ways (from 11.24 oz. pkg), chopped

1 pkg. Oreo cookie pie crust (I just used graham)

In bowl, whisk together sweetened condensed milk and Nutella until blended.  On medium-high speed, beat 1 1/3 cups cream until soft peaks form.  Fold into chocolate mixture.

Stir chopped candy bars into mousse mixture.  Transfer 2 cups to a freezer-proof bowl.  Spread remaining mixture in pie crust; freeze pie and reserved filling for 1 hour.  Mound reserved filling over top of pie.

Cover pie; freeze until filling is set, about 8 hours.  On medium high speed, beat remaining 1 cup of cream until soft peaks form.  Spread whipped cream over pie.  If desired, garnish with additional sliced candy bars.
