Key Lime Pie Bars mean working smarter, not harder.
Key Lime Pie Bars mean working smarter, not harder.There are a few reasons I transformed my favorite Key Lime Pie , into bars. Mainly, they are really easy to cut and serve this way, as a simple finger food–no fork (or even plate) needed. They're also easier transport in a baking dish with a lid, to stack in the fridge, etc. You can also double the recipe in a 9×13” pan to feed more guests, very easily. And the best part is they're just as delicious as “pie” with a creamy, tart lime filling.
How to make Key Lime Pie Bars:
Make Graham Cracker Crust: Mix sugar, melted butter, and graham crackers together then press into an 8″ square baking pan. Bake for 10 minutes at 350°F then let cool.
Make Filling: Beat cream cheese in a mixing bowl until smooth, then add sweetened condensed milk, lime juice, and lime zest, mixing until smooth. Pour over graham cracker crust and bake for 10 minutes. Cool for 30 minutes then refrigerate for at least 3 hours before serving with a dollop of whipped cream, if desired.
Make Ahead and Freezing Instructions:
To Make Ahead: The bars can be made up to 3 days ahead of time, stored in the fridge. The graham cracker pie crust could be made several days ahead, stored at room temperature or in the fridge.
To Freeze: Cover pan tightly with plastic wrap and aluminum foil and freeze for up to 3 months. Thaw overnight in the fridge before serving.

I’ll say it was very easy to make and minimum baking time which is plus for summertime desserts. But I didn’t care for the taste. It was too sour for me. Sort of makes sense with all that lime juice you use to counterbalance the sweetness of the condensed milk. I decided to make whipped cream to top it up thinking it will bring more balance to the pie but didn’t help much.
10 minutes is not nearly enough. It was still soupy. It went 20-25 minutes and was still wiggly.
Brought this to a dinner party for 25. I doubled the recipe to make in a 9X13 pan (cooked it for 15 minutes). It was a big hit! A friend texted to say they were even better the next day!
This is our new summer favorite. Easy to make and delicious! Could I substitute orange zest and fresh orange juice for the lime to make this more of a dreamsicle flavored pie? And if so in what proportions? Thanks!
Has anyone used sweetened, condensed coconut milk and df cream cheese for this recipe?
I made these yesterday and they were PERFECT! I used a GF cookie as the crust base but everything else was exactly as the recipe said and my family loved them! Thanks for this recipe!
The Key Lime Bar dessert has become a favorite go to recipe!
