How to Make It
Preheat oven to 325°. Combine first 4 ingredients (through salt) in a medium bowl, stirring with a whisk. Add butter to bowl; toss to coat evenly.
Press pretzel mixture firmly into bottom and up sides of a 9-inch glass pie pan. Bake 12 to 15 minutes at 325° or until lightly browned; cool completely on a wire wrack.
Press softened ice cream evenly into cooled crust, smoothing with a rubber spatula. Cover with plastic wrap and transfer pie to freezer; freeze 3 hours or until firm.
Combine strawberries and sugar in a medium bowl; toss to coat. Let stand 15 to 20 minutes. Spoon strawberries over ice cream pie. Drizzle with chocolate syrup, if desired.
