I adapted these Key Lime Pie Bars from my favorite Key Lime Pie recipe, and they are amazing! I love the idea of serving pie in “bar” form for parties. They’re easy for people to grab, they look beautiful, and taste even better!
How to make Key Lime Pie Bars:
- For the crust, combine the graham cracker crumbs, sugar, and butter and press into an 8” square baking pan. Bake at 350 degrees F for 10 minutes. Allow to cool before adding filling.
-
Add cream cheese to a mixing bowl and beat well with electric beaters until smooth. Add both cans of sweetened condensed milk, lime juice, and lime zest and mix again until smooth.
-
Pour over prepared graham cracker crust and bake in preheated oven for 10 minutes. Allow to cool for about 30 minutes, then refrigerate for at least 3 hours, before serving.
-
Cut into squares and top with fresh whipped cream, if desired.
Make Ahead and Freezing Instructions:
To make ahead, prepare and bake the pie up to 3 days in advance, stored in the refrigerator. The filling and crust can both be prepared separately, in advance, and then assembled and baked when ready.
Baked Key Lime Pie can be frozen for up to 3 months. Thaw overnight in the refrigerator before serving.

RATE and COMMENT below! I would love to hear your experience.
I originally shared this recipe June 2015. Updated November 2020.
I made this recipe and it was fantastic. I am definitely keeping this one for next year
I would love to make these for Thanksgiving but how can you double or even triple the recipe but still use an 8×8 pan?
I look forward to a response, Thanks
I’d use TWO 8*8 pans of cook them in two batches! Happy Thanksgiving!
Whoo-whee! These are FABULOUS! My daughter made these for a party, and everyone raved. The flavor was perfect. They are superior (by far) to any Key Lime bar or pie I have ever had. Now I’m “stealing” the recipe. Good work and thanks!
I’ve made these multiple times. So easy and refreshing!!
Already had all the ingredients for this, so, decided to try it out. Not a fan. Was left with gummy ‘crust’, with filling that defeated the purpose of a dessert bar, as you’d be better off eating it, with a spoon.
Hi Decca, did you bake it for 10 minutes after putting the filling in? That’s what helps set the bars. Before that happens, it’s more liquidy. When the recipe is followed exactly, it is pretty fool proof. Try again- they’re fantastic!
I always get rave reviews when I make these. I often make them for new neighbors as a welcome gift and also my grandchildren often request these. I’ve made these bars for families with children in the neighborhood and the kids always say this is now their favorite cookie. Thanks for sharing this great recipe.
Absolutely delicious! Made these for a church BBQ, and they were a big hit. I doubled the recipe and used a 9×13 pan. I increased final baking time by about 8 minutes. Thanks for the great recipe!
These are more sweet than tart. You evidently can’t skip to recipe because there are details left out of the instructions. My 8×8 pan must not be the same size as the author’s 8×8 pan. I had almost half the filling leftover. Probably won’t come back to this recipe.
Elizabeth, Sorry to hear you didn’t love the recipe. Not sure what went wrong but I’ve made this dozens of times and it always fits in an 8×8 pan. You can check through the other comments too. I’m wondering if you accidentally doubled or tripled the recipe by hitting the 2x or 3x button on the side. (Doubling or tripling the recipe would mean using a bigger pan or multiple pans!)
