Key Lime Pie Bars
With a creamy filling that is both tart and sweet and a coconut graham cracker crust, these Key Lime Pie Bars are the definition of summer in one perfect bite! These bars are easy to make and a great alternative to a traditional key lime pie.
I don’t know if you happened to catch my post last week for Key Lime Pie Ice Cream, but I’ve pretty much been obsessed with key lime everything since then, so I thought it was the perfect time to share these super simple Key Lime Pie Bars with you.
They’ve been on the site for ages, but they were definitely in need of a little refresh, so I tweaked the recipe and added new photos.
And now I’m just over here contemplating what key lime dessert to whip up next!
EASY KEY LIME PIE BARS
I love key lime pie. I love the tart flavor of the key limes, I love the creamy sweetness of the sweetened condensed milk, I love the pairing of the creamy filling with the graham cracker crust.
And unlike another classic citrus pie, lemon meringue pie, I love how simple it is to make key lime pie filling. Zero fuss.
But you also know that I love a good bar dessert. Being able to cut a dessert into bars and share it easily is one of my favorite moves.
So of course I had to turn key lime pie into bars!
Because key lime and coconut go so well together, I also wanted to add some coconut flavor to these bars.
I ended up adding some sweetened flaked coconut into the graham cracker crust. The coconut adds a subtle flavor and a bit of extra texture to the bars, which I love a lot!
HOW TO MAKE KEY LIME BARS
To make these bars, start by mixing together the graham cracker crust ingredients and pressing it down in a 8×8-inch pan that’s been lined with parchment paper.
I recommend leaving a “handle” of parchment paper over at least 2 sides of the pan. This will make it much easier to pull the bars out of the pan for cutting later.
To press the crust into the pan, grab a measuring cup or a glass with a flat bottom. Using the flat bottom of the cup or glass will make it easier to press the crust into an even layer!
Bake the crust for about 8 minutes while you whisk together the filling.
To make the key lime bar filling, just whisk the ingredients together in a bowl.
That’s it. I told you this was easy!
Pour the filling onto the baked crust and pop it back into the oven for about 12 minutes. You’ll know the bars are done when tiny pinholes burst on the surface of the filling. But be careful not to let the filling brown!
Let the bars cool on a wire rack and then chill in the fridge for several hours before using the parchment “handles” to gently lift the bars out of the pan, cut, and serve.
WHAT IF I CAN’T FIND KEY LIMES?
Finding fresh key limes at the store can be hit or miss. And honestly, tiny key limes are kind of a pain to juice anyway.
So here’s my secret: I buy key lime juice instead of fresh key limes.
My grocery store carries Nellie & Joe’s key lime juice, but any brand you find should work just fine.
If you do want to use fresh key limes, here’s a tip for juicing them: Use a (clean) garlic press to juice those tiny little suckers!
CAN I USE A 9X9 PAN INSTEAD?
I baked my Key Lime Pie Bars in an 8×8-inch pan. I like the thick layer of filling that you get when you bake them up in an 8×8 pan, but you could use a 9×9-inch pan instead.
If you’re using a 9×9-inch pan, the filling and crust layers will be slightly thinner, but equally delicious. Just reduce the baking time for the filling to 5-8 minutes instead of 10-12 minutes.
A HELPFUL TIP FOR CUTTING THESE BARS
Grab a large knife and run it under very hot water for a few seconds. Quickly wipe it dry on a clean towel and then cut the bars or cheesecake. The knife will be hot enough to cleanly cut through the filling.
Just clean the knife off between each cut, running it back under the hot water as needed if it starts to cool off.
Voila! Clean edges that will make you look like a pro.
