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.

And once the graham cracker crust is made, this is basically a 3 ingredient no-bake key lime pie.

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.
• 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.
• Graham Crackers.
• Butter. Salted or unsalted.
• Granulated Sugar

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. You may also find key lime juice on the juice or baking aisle at your grocery store. I’ve been making this pie long before key limes were available for me to purchase. I’ve made this key lime pie with Nellie and Joe’s Lime Juice, great flavor.
• 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.

How To Make This Recipe, It’s Easy

• Step 1: Place broken up sheets of graham crackers in a food processor.
• Step 2: Use the pulse feature to crush 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 3: Using a microwave safe bowl, melt the butter in the microwave for 30 second increments until melted. Add the sugar and stir.
• Step 4: Step 3: Add in the crushed graham crackers, and use a fork to blend well.

• Step 5: Use a small measuring cup to press the graham crackers into your pie pan. Use your fingers to form the crust up the sides of the pan. Refrigerate the crust for 2 hours before proceeding.
• Step 6: Make the filling for the pie. Use a whisk to simply mix the condensed milk, lime juice and thawed Cool Whip.

• Step 7: Use a spatula to spread the filling into prepared graham cracker crust. Cover with plastic wrap and refrigerate overnight. When ready to serve, top with an additional layer of Cool Whip and decorate with some lime slices.

Common Questions

How to decorate a Key Lime Pie

Tips For Success:

• Crust: You can purchase pre-crushed graham crackers on the baking aisle to make a pie crust, but try making your own. Purchase a box of graham crackers, It’s easy to make using a food processor. Plus you’ll have extra crackers left over for snacks.
• Preparing Crust: When pressing the graham cracker crust into the pan, don’t pack it too tightly. This will cause it to harden and become hard to remove from the pan when ready to serve. Just press it into the pan until it’s well formed to the bottom.
• Cool Whip: Make sure the Cool Whip has completely thawed. Place it in the refrigerator for a 4-5 hours or leave it at room temperature. You can also remove the lid and place it in the microwave for 30 seconds. Important: Use the setting for defrost.
• Refrigerate: For best results, once assembled, make sure to refrigerate No-Bake Key Lime Pie overnight. This will allow the dessert to set up and become firm enough for serving.
• Slicing: As with any cheesecake type dessert, use a sharp knife for slicing and serving. Each time you start a new slice, dip the knife in warm water and wipe clean with a paper towel. This will insure easy neater slices.
• This pie works well in a purchased chocolate pie crust, such as an Oreo pie crust. Or a regular pie crust. If using a chocolate pie crust garnish with thin slices of shaved chocolate and additional Cool Whip.

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.
