The first time I had this pie was when I was visiting my in-laws in Florida. My mother-in-law served it for dessert and I instantly loved it! It’s tart, sweet and creamy! It’s a delicious, frozen variety of Best Key West Florida Key Lime Pie. 

It’s the easy way to make a frozen key lime pie. I just love the tart taste of it.

What are Key Limes?

Did you even know “key limes” were a thing? They are different than regular limes in that they are more tart. Key Lime Pie is all over the Florida Keys. We had it in Key Largo and I just knew I had to bring back key limes in my suitcase!

Here’s what key limes look like:

They look just like regular limes but, as I mentioned are more tart. They make a great tart pie!

You may not find key limes at your local grocery store. If you can’t find fresh key limes, you can use regular limes or bottled key lime juice. However, fresh lime juice is best.

Now, there are many variations of the traditional key lime pie but, I find this one to be much less caloric than using whipped cream or cream cheese. It tastes just as great too.

This is the perfect dessert to make in the summer when you don’t want a hot kitchen. Sometimes, it gets so hot you cant even image turning on your oven for one minute let alone 45 minutes.

As I mentioned above, this no bake key lime pie is SUPER EASY to make with just four ingredients! See how delicious it looks!

Ingredients:

• 5 fresh key limes or 1/2 cup of bottled key lime juice
• 8 oz Cool Whip Lite
• 14 oz sweetened condensed milk
• graham cracker pie crust 
• 1 tsp key lime zest (optional)

If you can’t find “key limes” in the produce department of your grocery store, you can either use regular limes (but the pie won’t be as tart) or you can buy bottled key lime juice. I suggest using the bottled juice so you don’t sacrifice the extra tartness.

Ingredients:

• 5 fresh key limes or 1/2 cup of bottled key lime juice
• 8 oz Cool Whip Lite
• 14 oz sweetened condensed milk
• store-bought graham cracker pie crust 
• 1 tsp key lime zest (optional)

If you can’t find key limes in the produce department of your local grocery store, you can either use regular limes (but the pie won’t be as tart) or you can buy bottled key lime juice. 

Therefore, if you’re going to use bottled key lime juice, add some fresh lime zest to the key lime batter for extra fresh flavor and slice some of the lime for garnish.

Instructions

Add all of the filling ingredients in a large mixing bowl and combine well. Pour mixture into the pie crust, cover with plastic wrap and freeze overnight or eight hours. Keep it frozen until ready to serve. 

If you’re making this easy recipe with a Kitchen Aid mixer, use the paddle attachment to mix the key lime filling.

You can make your own graham cracker pie crust if you prefer. The instructions are below.

Garnish it with lime slices, whipped cream or some Cool Whip but, if you use Cool Whip for garnish, don’t forget to buy an extra container. 

 

How to make a graham cracker pie crust

Ingredients

• 1 1/2 cups of graham cracker crumbs or use gluten-free graham cracker crumbs
• 1/4 cup of sugar
• 5 tbsp melted butter

Instructions

Preheat oven to 375F. In a medium sized mixing bowl, add all of the ingredients and stir together until well mixed. Press the graham cracker mixture evenly into the bottom of an ungreased 8 or 9 inch pie plate.

Bake at 375F for ten minutes and cool before filling.

Alternatively, you may refrigerate the crust for 25 minutes  instead of baking it.

If you’re making the graham cracker crust with graham crackers, you’ll need to use a food processor to make fine crumbs before mixing them with sugar and butter.
