1. Preheat the oven to 350ºF (175ºC). Lightly butter a pie plate or pan with butter.
2. In a medium bowl, mix together the pretzel crumbs, sugar, and melted butter until the crumbs are saturated with the butter and everything is moistened and evenly mixed.
3. Transfer the mixture to the prepared pie plate or pan and use the heel of your hand to press the crust mixture across the bottom of the pans and up the sides.
4. Bake the crust for 8 to 10 minutes, until it’s slightly golden brown. Let cool on a wire rack.
