This Key Lime Pie recipe is a creamy tart pie made with a few simple ingredients. We've eaten our way through the Florida Keys many times and this dessert has all the perfect elements.
For the crust: Preheat oven to 350℉. In a medium bowl, combine the graham cracker crumbs, butter, and sugar until well combined. Press crumbs firmly into a 9-inch pie pan using your fingers or the back of a measuring cup. Bake for 8-10 minutes. Cool.
For the filling: In a large bowl, add the sweetened condensed milk. Zest the lime. Add the lime zest, lime juice, and sour cream or Greek yogurt. Mix together well. Pour into the cooled pie crust. Bake for 16-18 minutes or until center is not jiggly. Cool on the counter for until not piping hot. Then chill for at least 2 hours to allow pie to set up.
For the whipped cream: In a large cold bowl, beat the cream and powdered sugar on high until soft peaks form. Pipe onto pie or add to individual slices.
