Instructions

  • Preheat the oven to 350 degrees F.
  • In a medium bowl, mix together graham crumbs, brown sugar, and melted butter. Press this mixture into a 9-inch deep dish pie pan. 
  • Bake the graham crumb crust for 10 minutes. 
  • While that is baking, prepare the key lime filling.  Using an electric hand mixer, combine the key lime juice, zest, sweetened condensed milk, sour cream, 2 egg yolks, and powdered sugar
  • Pour the filling into the baked crust.
  • Bake the pie at 350 degrees F for 15 minutes.  It should be just slightly jiggly in the center.  If the pie is very jiggly, leave it in and check it every 5 minutes.
  • Remove the pie from the oven and allow it to cool to room temperature. Then refrigerate the pie for at least another 2.5 to 3 hours.
  • Serve with whipped cream and lime zest or lime slices if desired. 

Notes

Use key limes: You can use regular limes if you can't find key limes or key lime juice, but if you do spot key limes, grab plenty because they're so delicious and this should be the first dessert you make with them!
The right pie plate: You will need a deep dish pie plate for this dessert.
Check for doneness: The pie will be slightly jiggly in the middle when done. Mine took exactly 15 minutes. Don’t worry about the ‘jiggle’ by the way - the pie will firm up as it cools down.
