I have been making a classic key lime pie recipe for several years now. It’s one of my daddy’s absolute favorite pies so he requests it quite a bit during the year. If I don’t make him the homemade rendition, he is forced to order it at any restaurant we go to (heartbreaking I know). Thus, this how I became motivated to learn how to make key lime pie myself.

What Is Key Lime Pie?

Classic Key Lime Pie’s name came from the Florida Keys where small key limes originated.  The recipe starts with a filling made with condensed sweetened milk, key lime juice and egg yolks.  It becomes quite creamy, sweet and delicious.  It is then poured into a graham cracker crust and baked for a few minutes then completely set in the refrigerator before serving.

Most times it is garnished with whipped cream when served and additional fruit or served plain as is.

What is most important to understand is that the juice of key limes is crucial here.  You can’t replace with regular limes for key lime pie.  The good news here is that there are several key lime juice brands on the market that you can easily find in grocery stores or even online.  I usually use Nellie’s and Joe.

Ingredients for Easy Key Lime Pie Recipe Filling

Making key lime pie could not be easier. The base of my Easy key lime pie recipe is a very simple mixture of the following:
  • Egg yolks
  • Sweetened condensed milk
  • Key lime juice
  • Vanilla extract

Key Point: Make sure you are getting the sweetened condensed milk and NOT Evaporated Milk. 

The sweetened milk provides the sugar for this recipe and creamy consistency.  If you buy evaporated milk, you will have an unsweetened runny mess on your hands.

Graham Cracker Crust

If you want to make this pie baking process even easier, you can also buy a pre-made graham  cracker crust at the grocery store.  However I suggest trying my insanely easy Graham Cracker recipe because it is beyond simple to throw together and tastes even more incredible!
However it is so simple to make the crust that it won’t matter whatever you decide. This custard is poured into a graham cracker crust and baked for 15 minutes to set.

Simple Raspberry Swirl

There are many key lime pie recipes online but the small addition of warmed raspberry preserves swirled through the batter changes the game. It truly does make this the best key lime pie recipe online. The raspberry tartness is wonderful with the sweetness and tart flavor of the lime juice. It also makes such a huge difference in the presentation of the pie. The update is not only super easy but absolutely gorgeous and dramatic.

You can also sub in strawberry preserves if you want to switch up the berry vibes.

Other Key Lime Desserts

If you serve this raspberry key lime pie on any holiday, be ready to receive compliments galore. If you wanted to, you could also make this a multi berry key lime pie and add different flavors to it. That would be fun as well!
