Instructions
 

Make the Crust

  • In a medium-sized mixing bowl, combine graham cracker crumbs, sugar, and melted butter. Stir until well combined, resembling wet sand.
  • Press this mixture firmly into the bottom and along the edges of a pie dish.
  • Place the pie dish in the freezer for about 10-15 minutes to firm up the crust.

Make the Lemon Lime Pie Filling

  • In a mixing bowl, whip 3/4 cup of heavy whipping cream until stiff peaks form, then set aside.
  • Combine softened cream cheese with sweetened condensed milk, whipping until smooth and creamy.
  • Add in the lemon zest, lime zest, and vanilla extract, mixing until well incorporated.
  • Gently add sour cream, lemon juice, and lime juice, blending until fully combined.
  • Fold in the whipped cream with careful strokes, ensuring no streaks remain.

Assemble the Pie

  • Remove the crust from the freezer and pour the creamy lemon-lime filling into the crust, smoothing it with a spatula.
  • Chill the pie in the refrigerator for at least 2 hours or until it sets.
  • Whip the remaining 1/2 cup of heavy cream to soft peaks and spread it over the pie once set.
  • Garnish with lemon and lime slices for a burst of color.

Notes

For best results, use freshly squeezed lemon and lime juice. Prepare the pie crust a day in advance for convenience. All dairy ingredients should be at room temperature for smoother filling. Customize the pie with other citrus fruits or berries if desired.
