I love to bake sweet desserts. A lot. Cakes, cookies, crumbles, and crisps – and, of course, pies! Featuring a tender, firm crust and loaded with nearly any goodies you can imagine, homemade pies are simply the best, IMO.

But who wants to actually turn on the oven during the hot summer months to bake? (I mean, pies are amazing, but are they turn-your-kitchen-into-a-sweaty-mess amazing? Before you answer…)

Thankfully there are lots of delicious no-bake pie recipes to beat the heat! These recipes for Fluffy No-Bake Chocolate Banoffee Pie and Fluffy No-Bake Strawberry Cream Pie are just some of our classic favorites you’ve got to try.

We recently shared our super easy recipe for Lemon Icebox Pie, and it’s been a big hit. So we thought it should also be turned into an equally simple and amazingly flavorful No-Bake Key Lime Pie recipe.

This frozen Key Lime Pie is going to be your new go-to treat for summer. It’s so easy to throw together and make ahead for all of your backyard barbecues and potlucks!

The Best No-Bake Key Lime Pie

In the Lemon Icebox Pie mentioned above, we offered two ways to prepare: a two-layered version with a whipped topping, and an option where the Cool Whip is folded in with the pie mixture to make one layer.

For this recipe, we decided to simply mix all of the whipped topping into the key lime mixture to create a super light and fluffy single layer. This lime icebox pie is much more like a “Chantilly” Key Lime pie I had on Marathon Key last year. I swear it tastes just like being at the beach.

And it couldn’t be easier to prepare! Simply make a quick no-bake graham cracker crust, blend the filling ingredients (no cooking needed), pour the filling into the crust, and freeze. That’s it!

Before you know it you have a refreshing, bright, wonderfully sweet, and tart dessert that everyone will love to enjoy on a hot day!

Ingredients You Need

There are two main components included in our fabulous Key Lime Icebox Pie recipe: a graham cracker crust and the creamy, tangy lime filling.

You certainly can use a store-bought crust if you prefer, but you might be surprised by how easy it is to prepare from scratch. To make a homemade graham cracker pie crust you need:

  • Graham crackers
  • Butter
  • Granulated sugar
  • Salt

For the key lime pie filling you need:

  • Cream cheese
  • Sweetened condensed milk
  • Key lime juice
  • Lime-green food coloring (optional for that classic vibrant green lime color)
  • Cool whip

Key limes can be hard to find in some regions, but you can usually find bottled key lime juice in the baking or cocktail/beverage section of the market.

I also recommend garnishing the icebox pie with fresh lime zest for a hint of bright flavor.

How to Make a Graham Cracker Icebox Pie Crust

First, set out a 9-inch pie pan and a food processor. Place the graham crackers in the food processor. Lock the lid into place and pulse into a fine crumb. Then add in the melted butter, sugar, and salt. Pulse to combine.

  1. Totally loving it so rich and creamy!

  2. What do you think about stablized whipped cream instead of Cool Whip? I try to stay with whole foods. Thanks 😊

    • Clearly, I didn’t write the recipe, but made a chocolate one like this (King Arthur) and for that one, the recipe asks for 1 cup  of folded freshly made whipped cream and the pie turned out delicious. The one main difference was that I never kept it in the freezer, only refrigerator. I don’t know if that helps. 

    • Hi Cecily!

      Yes, you can absolutely use that instead of Cool Whip. :)

  3. So rich and creamy! My hubby loved it.

  4. I had two slices of this pie already! No joke! It’s incredible! Creamy, smooth and so tasty!

  5. We made this a couple weeks ago for family & it was gone within minutes! Everyone wanted the recipe. Will be making again soon!

  6. I am a key lime fanatic! I love this recipe so much! I also love that I can make two in one day and then freeze the second one for a later date when I need to bring a dessert to a dinner party, at the last minute!
