First, how about this from Yogi Berra:
The waitress asked: “How many pieces do you want your pie cut?” Yogi responded: “Four. I don’t think I could eat eight.”
About This Recipe and Why It Works
My husband’s side of the family recently gathered for their family reunion.
Bob’s sister and husband Vern hosted the event at their home with a spread of pot luck food that wow’d our crowd.
They laid out a feast of Slow Cooker Pulled BBQ Pork and sliced ham for sandwiches, coleslaw, fresh corn on the cob, calico beans, mac and cheese, fresh slices of watermelon…get the picture? (I hope so since I didn’t take any) :-/
And for dessert? This No-Bake Key Lime Pie Recipe with Cool Whip. And you know it must be easy if she had enough of these pies to feed about 30 people.
This is an excellent recipe to make-ahead, as it freezes well.
With it’s refreshing flavor and that “no-bake” factor, this is a great Summer dessert recipe. The filling is fluffy using Cool Whip, sweet with condensed milk and tart with lime juice. Amazing flavor with every single bite.
A bit if advice? Don’t save this one just for Summer, this is a year round dessert that everyone will enjoy.
No Bake Key Lime Pie Ingredients:

How can something this easy really be this delicious? Let’s take a look.
- Sweetened Condensed Milk: You’ll find it on the baking aisle at the grocery store. What is sweetened condensed milk? It’s thick, it’s sticky and not for drinking. Condensed milk is made by removing the water. It’s cooked down to remove moisture. Just like you would a balsamic glaze or red wine reduction. Then sugar is added to prolong shelf life. The sugar prevents microorganisms from growing and sugar thickens this milk even more. Unsweetened condensed milk is sold as evaporated milk.
- Cool Whip: Talk about a science project. Cool Whip is an imitation whipped cream sold as “whipped topping”. Cool whip has a long list of concerning ingredients and contains very little dairy. With that said, I love the stuff. I could (and have) eaten it by the spoonful from the container. It’s delicious. And this key lime pie with Cool Whip is extremely popular.
- Key Lime Juice: What are key limes? Key limes are known as Mexican or West Indian Limes. They’re more aromatic and more floral in flavor than regular limes.
- Pie Crust: If you want to make this key lime pie easier than easy, purchase a pre-made graham cracker or chocolate pie crust from the baking aisle at the grocery store. You can also make your own graham cracker crust or chocolate crust. I’m thinking an Oreo pie crust might be fab here.
Ingredient Notes and Ingredient Swaps
- Can’t find Key Limes? You can use regular limes. You’ll need to squeeze enough juice to make 1/2 cup of lime juice. You’ll need 4 – 5 full sized limes. Or purchase Nellie and Joe’s Famous Key Lime Juice. I’ve been making this pie long before key limes were available for me to purchase. I’ve made this pie many, many times with Nellie and Joe’s, great flavor.
- Can I use Homemade Whipped Cream? I’ve not tried it, but I doubt it would hold up to create a dense fluffy texture like Cool Whip. Let me know if you try it.
- Can I Freeze This Pie? This is one of its best attributes. If you’re making this for a crowd, you can make a couple of these pies ahead of time and freeze. Simply allow an overnight thaw in the refrigerator before serving.
How To Make This Recipe

First, we’ll prepare this easy graham cracker crust.
- Step 1: Using a food processor crush full sheets of graham crackers to a grainy consistency. If you don’t have a food processor, break up the crackers with your hands and place them in a zip lock bag. Seal, pressing the air out and use a use a rolling pin to crush them to a grainy state.
- Step 2: Using a microwave safe bowl, melt the butter. Add the sugar and stir.
- Step 3: Add in the graham crackers, and mix using a fork.

- Step 4: Using a small measuring cup, press the graham crackers into your pie shell. Use your fingers to form the crust up the sides of the pan. Refrigerate the crust for 2 hours before proceeding.
- Step 5: Make the filling for the pie. Using a whisk, simply mix the condensed milk, lime juice and thawed Cool Whip.
- Step 6: Using a spatula, spread the filling into prepared graham cracker crust. Cover with plastic wrap and refrigerate overnight.
How to decorate a Key Lime Pie
Presentation Tips:
- Purchase some extra cool whip and spoon it into a pipping bag. Pipe swirls of whipped topping around the edge, or dollop them spaced on top of the pie.
- If you use the chocolate crust, dress up the top of each slice of pie with a bit of shaved chocolate for chocolate curls. How do you make chocolate curls? Just take a bar of semisweet chocolate. I like to refrigerate the chocolate first. Then I simply use a box grater, the side with the slicer. Or you can use a very sharp paring knife to very thinly slice the chocolate.
- Decorate with thin sliced limes. Using a knife, make a single cut to the center of the lime. Then twist it.
- Making this no-bake key lime pie with Cool Whip in a 9″ tart pan will give it an even snazzier look.
I think it takes longer to get the items out of the pantry than it does to throw this key lime icebox pie recipe together.

Key Lime Pie Recipe No Bake …It’s What’s For Dessert.
Key lime pie is one of my favorites–this looks really good. 😉
I love key lime pie and order it every time I see it on a menu. I got a good laugh out of Yogi’s comment on how to cut the pie. I’ll have to remember that one.
Enjoy the King exhibit. Makes me wish I lived closer to a city instead of out in the woods.
Sam
I could eat eight, no problem ;).
Great looking pie. I’m a big fan of any dessert that doesn’t require firing up the oven, particularly with the heat we’ve been having.
I would love to have a slice of that. It sounds so simple but looks so yummy!
We are undeafeted!!!!!!! Yeah!
This looks positively luscious! Rich and refreshing. And I love that quote!
Looks great! Chicken Legs LOVES key lime pie. I love that this is no-bake.
This is my favorite pie in the whole world! yours came out great!
Ooooo, I’d love a piece of this pie now, even if it is only 8:00 in the morning. I have no excuse not to make this as it is such an easy recipe.
Looks delicious!
This sounds great – I think I could even make it 😉
Mmm, looks delicious!
I just found a little baggie of key limes and brought them home. I had never seen them up here before. They are tiny!
This is one of my very favorite summertime pies! (And I love the yogi berra line!)
I hope so because I didn’t take any…LOL!!! Sounds like a feast I would LOVE! This sounds so nummy…is it sweetened condensed milk or evap milk?? I love key lime cake…but haven’t found a key lime pie I can love yet. Must try! 🙂
It’s that ooey gooey sweetened condensed Eagle Brand Milk. I should go back and change the post.
I love that Yogi Berra quote. And I love anything that has anything to do with key lime pie. Delicious.
Mmm, I would love this right out of the freezer. Cute quote by Yogi Berra… LOL
Good idea Karen. I divided up pieces and they’re in the freezer. Next time I want one for dessert I won’t let it thaw.
I have made a key lime pie once. I loved it but nobody else in my household did. That was very disappointing. I still think it is a great tasting pie. Maybe I should try a different recipe?
I can’t imagine anyone not liking this recipe…cool whip and that thick sugared milk. yum. Tell them it’s something else….like call it a refrigerator pie.
I’m going to make this pie for my lovely bride (of 25 years). It better be as good as you say. Thanks.
Well heck, if you don’t like it please don’t hunt me down! 🙂 All kidding aside, please let me know how you liked the recipe.
Oooh! It just so happens that The Niece loves key lime pie! This sounds lovely and easy. Gonna have to make this the next time I see her…
You better make a test pie in the meantime for you and Zio.
I like your thinking on this 😉
I love key lime pie! It is so refreshing and sweet at the same time!
Beeyootiful! And the pie is as pretty as the ginkgo leaf dish. 😉 Seriously, it sounds delicious – I love key lime pie and had no idea it was this easy. Sweet!!
I’ve got four of those plates, they make great little salad plates, especially on my periwinkle blue dinner plates. You should give the pie a try, it’s really good….and rich.
I love key lime pie and this sounds very fattening, I mean good.
We each ate about 1/2 of a slice and it went straight to the freezer to portion out in future slivers. 🙂
