1. Preheat oven to 350°F. Process pretzels, waffle cones, and brown sugar in a food processor until finely ground and well combined, about 20 seconds. Add butter; pulse until mixture resembles wet sand, 6 to 8 pulses.
2. Press mixture evenly into bottom and up sides of a lightly greased (with cooking spray) 9-inch pie plate. Bake in preheated oven until golden brown and crisp, 8 to 12 minutes. Transfer to a wire rack; let cool completely, about 30 minutes.
