Pretzel Ice Cream Pie

1. Using your hands (or a food processor if you prefer), crumble the pretzel crunch clusters to half their size. (The smaller size will make for better distribution of the moisture and fat, creating a nice crunchy crust.)
2. Toss the melted butter into the crumbled pretzel crunch, mixing well. Using your fingers and the palms of your hands, press the mixture firmly into a 10-inch pie tin, making sure the bottom and sides of the pie tin are evenly covered. Wrapped in plastic, the crust can be frozen for up to 2 weeks.
3. Use a spatula to spread the ice cream into the pie shell. Freeze the pie for at least 3 hours, or until the ice cream is frozen hard enough so the pie is easy to cut and serve. Wrapped in plastic wrap, the pie will keep for 2 weeks in the freezer.
