Step 1

Combine the graham cracker crumbs, brown sugar, salt and butter and press into a 9-inch pie dish. Put in the freezer while you prepare the filling.

Step 2

Whisk together the sweetened condensed milk and marshmallow cream until smooth. With an electric mixer, beat the heavy whipping cream to medium peaks. Gently fold into the marshmallow mixture.

Step 3

Spoon the filling into the pie dish. Depending on how deep your dish is, you may not need all of the filling. Freeze for at least 2 hours.

Step 4

Spread the fudge sauce over the top of the pie and freeze until pie is completely firm, about 4 hours more or overnight.

Step 5

When ready to serve, top with mini marshmallows and graham cracker pieces. For easier slicing, dip a sharp knife in hot water and wipe dry with a towel in between cuts.
