What are Key Limes versus regular limes?

If you can find them, key limes are great! But as they can be challenging to find and not always available, regular Persian limes work wonderfully in our opinion.

That said, my family loves the flavor of limes but we are not an expert in limes. So I did a little google research and am linking an article from Taste of Home magazine from June 2020.

This article provides all sorts of information about the different variety of limes, when and where they are grown and how they differ, all of which was quite fascinating to me!

But here’s my non-expert summary — Key Limes (not always from the Keys) are smaller and have a distinctive flavor compared to Persian Limes (the ones we usually see in the grocery store). We have used both types to make the pie and these bars, and to our non-expert palate, they both work great!

And the filling comes together in 3 simple steps:

  1. Mix the cream cheese until soft and creamy.
  2. Add in the egg yolks and whisk until well combined with the cream cheese, and creamy and smooth.
  3. Add in the condensed milk, limes and lime zest and whisk until well combined. The filling will be thick and creamy.

Pour the filling onto the cooled graham crust and bake for 15-18 minutes.

It really couldn’t be easier or quicker!

Let cool in the pan at room temperature, then move to the refrigerator for 2-3 hours or overnight as I usually do.

When ready to serve, just lift the parchment paper right out of the pan and slice!

Pro tip, how to cut key lime bars: For clean slices, make sure the bars are cool and use a sharp knife that has been run under hot water. This help give the cleanest slice. I will often gently wipe the knife in between slices for the best results.

To make them look extra special and festive, top with a dollop of whipped cream  (we love the Cabot Whipped Cream in a can), and then with a sprinkle of lime zest!

They will look beautiful and taste even better!

Hope you love them a much as we do!

  • ¼ teaspoon ground nutmeg
  • pinch salt
  • 1 large egg white
  • 3 tablespoons butter or dairy-free butter, melted

Key Lime Filling

  • 4 oz cream cheese or dairy-free cream cheese, room temperature it is important that it is room temperature so that it mixes well with the egg yolks
  • 4 large egg yolks, room temperature use one egg white for the graham cracker crust, and save the others for an egg white omelette or scramble.
  • ½ cup + 1 tablespoon lime juice juice of 3-4 limes depending on size
  • 2 teaspoons lime zest, packed zest of 2 limes
  • 1 14oz can sweetened condensed milk or sweetened condensed coconut milk if dairy-free


Graham Cracker Crust

  • Preheat oven to 350 degrees F and line an 8 inch pan with parchment paper, set aside.
  • In a large bowl, mix all the graham cracker crust ingredients with a mixer or by hand until well combined.
  • Press into the parchment lined pan using your fingers until it makes one even layer.
  • Bake for 10 minutes, until set and just golden. Let cool and set aside.

    I made this recipe today and the filling didn’t set. The crust was very good but I’m not sure what I did wrong but the filling was not good. I used vegan cream cheese so maybe that’s the problem. The filling was runnier than I expected and stayed that way even with an additional 8 minutes in the oven. Also it was quite sweet. Maybe the vegan cream cheese.

    1. hmmmm, I’m sorry you had that problem. I’ve made this many times and it’s always set in the time frame and it’s actually more tart than sweet… the vegan cream cheese shouldn’t have made a difference as long as it was the correct quantity, so I’m honestly not sure what happened… except, did you increase the oven temperature to 375 degrees after taking out the graham cracker crust? Oven temperature could have caused it not to set…
