A Key lime yogurt pie is like captured sunshine in a cool, creamy, no-bake dessert. You don't even need real Key limes!
Although Key limes can be hard to come by in some areas, it’s not a problem with this dessert. All you need to make Key lime yogurt pie is Key lime-flavored yogurt, lime Jell-O and frozen whipped topping. The fluffy filling sits in a toasty graham cracker crust; use a store-bought version, and this his refreshing, citrusy no-bake dessert couldn’t be easier. Like traditional Key lime pie or other Key lime recipes, this pie is fantastic any time of the year, but it’s particularly delicious for spring and summer cookouts, potluck picnics or a Sunday brunch menu.
Key Lime Yogurt Pie Ingredients
- Lime gelatin: It’s no secret that we love retro Jell-O desserts. Here, lime gelatin gives the pie its green color and helps with the fluffy texture.
- Key lime yogurt: Key lime yogurt adds tang and creaminess to the pie filling. For the most vibrant flavor, avoid light-textured whipped yogurts.
- Frozen whipped topping: Whether using Cool Whip or store-brand frozen topping, allow it to thaw for several hours or overnight in the fridge before mixing it with the other ingredients.
- Graham cracker crust: Premade graham crusts are a convenient choice, but it’s easy to make a graham cracker crust from scratch.
Directions
Step 1: Prepare the filling
In a large bowl, add boiling water to the gelatin. Stir for two minutes to completely dissolve the gelatin. Whisk in the yogurt, then fold in the whipped topping. Pour the mixture into the graham cracker crust.
Step 2: Chill
Cover the pie and refrigerate it for at least two hours until it’s set.

Key Lime Yogurt Pie Variations
- Try a different crust: Other crumb crusts, like ones made with vanilla wafers or gingersnaps, work with this pie. A chocolatey Oreo cookie crust also pairs well with the lime filling.
- Try homemade whipped cream: Replace the frozen topping with homemade whipped cream made from sugar, vanilla and heavy cream.
How to Store Key Lime Yogurt Pie
Because the filling contains yogurt and cream, Key lime yogurt pie should be stored in the refrigerator. Cover the pie tightly with food storage wrap or transfer it to a sealed dessert carrier. Leftover pie should also be returned to the fridge as soon as possible after serving.
How long does Key lime yogurt pie last?
Key lime yogurt pie will last up to five days in the fridge.
Can you freeze Key lime yogurt pie?
It is possible to freeze a Key lime yogurt pie made with gelatin, but only if you plan to serve the slices frozen. Trying to thaw the pie from frozen will leave the filling loose and watery. Cover the set pie tightly with freezer-proof pie wrap and store it in the freezer for up to three months. It can join your other favorite frozen dessert recipes.
Key Lime Yogurt Pie Tips

How do you get a clean slice of no-bake pie?
The first step to getting a clean slice of Key lime yogurt pie is ensuring the filling sets completely. Chill the pie for at least two hours, or plan for several hours or overnight if possible. Run a sharp chef’s knife (one of four must-have kitchen knives) under warm water and dry it before slicing the pie. Have a damp paper towel ready to wipe the knife clean between slices. Then, carefully use a pie knife to move the slices onto dessert plates.
Can you make this yogurt pie in other flavors?
Yes, this Key lime pie with lime Jell-O is so easy to make that it’s worth experimenting with other fruity flavors! Pair gelatin mix with yogurt flavors like peach, cherry, raspberry or strawberry. Combine them with the thawed whipped topping as the recipe directs, and then chill the pie.
