Key Lime Icebox Pie

The classic Southern pie gets a makeover with a cream cheese filling and a pretzel crust.
  • Crust:
  • 2 cups graham cracker crumbs
  • 1 cup finely crushed pretzels
  • ¾ cup plus 2 tablespoons unsalted butter, melted and divided
  • ¼ cup sugar
  • Filling:
  • 1½ (8-ounce) packages cream cheese, softened
  • ⅔ cup confectioners’ sugar
  • ¼ cup bottled Key lime juice
  • 1 teaspoon orange zest
  • ¼ cup fresh orange juice
  • 2 teaspoons lime zest, divided
  • 5 cups frozen whipped topping, thawed
  • Garnish: crushed pretzels, orange zest, lime slices
  1. Spray a 10-inch cast-iron skillet with baking spray with flour.
  2. For crust: In a large bowl, toss together cracker crumbs, crushed pretzels, ¾ cup melted butter, and sugar until moistened. Add remaining 2 tablespoons melted butter, if necessary. Using the bottom of a measuring cup, press mixture into bottom and up sides of prepared skillet. Freeze for 15 minutes.
  3. For filling: In a large bowl, beat cream cheese with a mixer at medium speed until creamy. Add confectioners’ sugar, lime juice, orange zest, orange juice, and 1 teaspoon lime zest, beating until combined. Fold in whipped topping. Spread filling into prepared crust. Sprinkle with remaining 1 teaspoon lime zest.
  4. Loosely cover and freeze until firm, at least 6 hours. Thaw in refrigerator until softened, about 1 hour, or at room temperature for 30 minutes before serving. Garnish with pretzels, orange zest, and lime slices, if desired. Cut with a sharp knife dipped in hot water.
