Equipment

  • 9" pie pan

Ingredients

Crust:

  • 1 1/2 cups graham cracker crumbs finely crushed
  • 3 tablespoons granulated sugar
  • 1/3 cup butter melted

Filling:

  • 2 14 ounce cans sweetened condensed milk
  • 3/4 cup sour cream full fat
  • 3/4 cup lime juice fresh squeezes
  • 1 tablespoon lime zest
  • 1 teaspoon vanilla

Optional toppings:

  • 1/4 cup slivered almonds
  • 1/2 cup your favorite raspberry preserves for raspberry sauce
  • whipped cream

Instructions

  • Preheat the oven to 350 degrees.
  • Combine the graham cracker crumbs and sugar in a medium bowl. Fold in the butter and blend well. Press into the bottom and up the sides of a 9" pie pan (ungreased).
  • Refrigerate the pie shell while you blend the filling.
  • Blend the sweetened condensed milk, sour cream, lime juice and zest and vanilla by hand.
  • Pour into the prepared pie shell and bake for 8-10 minutes or until small bubbles begin to form (don't overbake!).
  • Remove the pie from the oven. Cool completely then refrigerate several hours (or overnight) before serving.
  • Top with whipped cream and slivered almonds. To make the raspberry sauce, add 1/2 cup to a small bowl. Microwave 15-20 seconds or until it's warmed. Drizzle the sauce over each slice when served.
