In the bowl of a stand mixer, whip the cream until thickened (but before it becomes whipped cream).
With the mixer running add the milk, sweetened condensed milk, and vanilla (plus 2 T vodka or peach schnapps, optional, to keep it scoopable). Pour into a metal loaf pan, and place in freezer for one hour.
Roughly chop two pieces of peach pie. Remove the pan from the freezer and stir in the pie.
Return to the freezer and freeze until solid.
