Easy Key Lime Pie Recipe, a Fifth Wheel and a Cat 4 Tornado

What does this easy Key Lime Pie recipe, a Fifth Wheel and a Tornado have in common?  

Well, just this past week, Southwest Florida has been experiencing hair-raising weather, with Cat 4 Tornado warnings, flood warnings and some folks have experienced tremendous wind damage to their homes and properties.  We were lucky – lots of rain and wind, but no damage.

The last couple of weeks I’ve been enjoying life in sunny Naples, Florida with my husband Mark and our three pooches, Barkley, Max & Millie.  The average temperature has been between 75 and 85 F, near perfect for this Canadian girl during the month of January.  We’ve parked our Fifth Wheel here for the winter at Neapolitan Cove RV Resort and are both embracing the lifestyle and the warmth.  It’s a beautiful spot, sunny and warm, with lots of time for the beach and playing golf.   They even have a beach for dogs!


We Love Key Lime Pie!
We’ve been exploring, trying out some of the local restaurants or barbecuing at home.  Oh and eating pie.  Did I mention that we both have developed a fondness for Key Lime Pie?  Well here in Florida, you can find it on just about every restaurant menu and since I always look at the dessert menu first – (doesn’t everyone?) I’ve been able to sample a few different recipes and decided I needed to share an easy key lime pie recipe with you!

Key Lime Pie was invented by a Key West cook, called Aunt Sally and there are many recipe variations out there.  Key Lime Pie is usually made in a graham cracker crust, and is a baked pie that includes egg yolks, condensed milk, and fresh key lime juice.   Some are topped with whipped cream, and others have delicately browned meringue topping.   But for this no bake easy key lime pie recipe, we’ll stick to the whipped cream topping!

Now I love to bake and whipping up a graham cracker crust is easy to do.  Heck I could even buy a graham cracker crust courtesy of Mr. Keebler!  And instead of fresh key limes, there is always ✅ Nellie and Joe’s Famous Key West Lime Juice .  After all, this is an Easy Key Lime Pie Recipe!  We do have a propane oven in our Fifth Wheel that works really well.   But I wanted to see if I could create a Key Lime Pie filling made the same way I make my Lemon Meringue Pie – on top of the stove.

The ingredients for my easy key lime pie recipe are similar, however instead of corn starch that is the thickener for lemon pie – key lime pie uses sweetened condensed milk and it’s the combination of this and the lime juice that causes the filling to thicken.  For those that have made a lemon pie, you know that mixing the ingredients takes a few extra steps – you can’t throw all of the eggs into the hot lemon mixture since you would end of with lemony scrambled eggs!  But this little extra effort is so worth it!  So with that in mind I set to work to see if I could convert a pie recipe made for baking in an oven, to a cooked pie filling, just like this easy key lime pie recipe.

The result?

Easy Key Lime Pie Recipe

a delicious and easy key lime recipe that is quick to put together and cooks on top of the stove. Perfect for RV life and travel!


  • 1 graham cracker crust - 9"
  • 4 large eggs
  • 1 14 oz can sweetened condensed milk
  • 1/3 cup key lime juice
  • 1/4 cup of white sugar


Separate the eggs, put the whites in the freezer!

  1. Beat the egg yolks in a large saucepan until thick with medium speed on your mixer.
  2. Stir in the condensed milk and key lime juice
  3. Cook on the stove on medium-low, stirring constantly until the mixture starts to thicken. Don't leave it or it will stick to the pan and we don't want that to happen!
  4. Once the filling has thickened, remove from heat and let it cool just a bit. Pour it into the graham cracker crust pie shell and set aside to cool. 
  5. Garnish with Whipped Cream, Lime Zest and thin slices of fresh lime.  This is the very best key lime pie you will ever make!


Garnish: I use thin slices of key limes, along with a sprinkle of lime zest.

Can this filling be frozen?

Hi Sandie - I've never frozen it myself, not sure how the condensed milk would react to that. It will keep in the fridge for a few days though if you want to make it ahead.

Hi there, getting ready to make this when I noticed a 1/4 cup of white sugar that is not included in the directions... misprint or does that go in the whipped cream...or what? Thanks

Hi Patti! The 1/4 cup of sugar is for the whipped cream, thanks for catching this! I'll be sure to make the adjustment. Thanks so much.
