One easy recipe for no-bake key lime pie requires the baker to combine cream cheese and condensed milk in a mixing bowl. Stir in vanilla extract and key lime juice, then pour the mixture into a prepared pie shell. Refrigerate the mixture overnight, and top with lime zest before serving.
To prepare the no-bake key lime pie, microwave 8 ounces of cream cheese for about 15 seconds to soften it, then add to a large mixing bowl. Pour in 1 14-ounce can of sweetened condensed milk. Use an electric mixer on low to beat the cream cheese and condensed milk together, gradually increasing the speed until the mixture is smooth. Stir in 4 ounces of key lime juice and 1 teaspoon vanilla extract.
Pour the mixture into a store-bought graham cracker shell pie crust. If you prefer to make your own graham cracker crust, use a food processor to pulse 10 sheets of graham crackers into fine crumbs. Mix the crumbs with 6 tablespoons of melted butter and 1/3 cup sugar. Press the crumb mixture firmly into the bottom and sides of a pie pan, packing it down with the back of a measuring spoon. Chill the homemade graham cracker crust for two hours before adding the key lime mixture.
Place the key lime pie in the refrigerator to chill overnight, or for at least three to four hours. Sprinkle lime zest over the pie, and serve slices with a dollop of whipped cream.
