    Easy Key Lime Pie Recipe

    This Easy Key Lime Pie recipe is a perfect summer dessert! Not only is it cool, creamy and refreshing, it is also easy to make! Sponsored by Clever Girls Collective.

    key lime pie slice

    With Easter just around the corner, I’ve been thinking about Easter dinner with ham and all the trimmings which is always delicious but the highlight of these family dinners is the dessert.  We usually have pie at our holiday meals so I decided to try to make my very first key lime pie.

    I am all about finding easy, yet delicious desserts so I made this Easy Key Lime Pie with COOL WHIP Whipped Topping as one of the main ingredients!

    mix jello and yogurt in bowl

    Whisk lime gelatin into boiling water and stir until dissolved.  Then, add the key lime or lime juice (fresh squeezed or bottled). Once the gelatin mixture has cooled, add the key lime pie yogurt.

    fold in cool whip

    Add one container of COOL WHIP and green food coloring, if desired.  The food coloring was the last thing I added because after mixing everything together, I realized that I wanted to make the green more noticeable.

    spread in crust

    Spoon mixture into graham cracker crust and smooth out.  Place in the refrigerator to set for at least 2 hours.

    lime peel curl

    To make a lime curl, I cut a slice of a lime and then cut off the green part of the peel.  The peel didn’t want to stay curled up so I twisted it around a pencil and let it sit while pie was setting.

    key lime pie slice

    Put slices of pie onto plates, top with a dollop of COOL WHIP from the second container and add the lime curl.

    My husband has always been a huge key lime fan, but I had never tried key lime pie until last Christmas at my in-laws. I really enjoyed it and have wanted to try making my own.

    This recipe was easy to make and I am so happy with the results. Now, I want to try this same recipe using various flavors of gelatin and yogurt!  Just picture trying strawberry, lemon, raspberry or cherry.

    It would even be fun to mix the gelatin and yogurt flavors by making a raspberry/lime pie or strawberry/lemon pie which would probably taste like strawberry lemonade!

        Hello Eloise,
        I’ve never tried substituting the yogurt with something else in this recipe so you’ll have to experiment a little to see what works. I would suggest trying some softened cream cheese, prepared vanilla pudding, sweetened condensed milk, or more Cool Whip.
        Warmly,
        Tonia

      I love this recipe and make it often, but instead of boiling water to dissolve the jello I heat up a 1/4 cup of lime juice …..really adds to the flavor !

      My intention was to make a lemon-lime kool aid pie but I couldn’t find the kool aid mix but had my heart set on lime. So I found this recipe. I didn’t have key lime juice but I did fresh squeeze 2 very small limes. This pie turned out so much better than I expected and my family really enjoyed it. They’re already making plans for when it will be made again😂 Thanks for the great recipe and easy directions. Pinning now!

      This is not a true Key Lime Pie. Nothing key lime about it. Fake taste for sure. Too much Yogurt taste. A true Key Lime pie has at least 1/2 cup of Key Lime juice in it to give it a nice tart taste. This is far from it. Will not make this again. Such a waste of time and ingredients.

      I have made this about 8 times. I use 2 Tablespoons of key lime juice and the taste is awesome. I even used a 10″ premade graham shell and adjusted the ingredients. It came out great. Nothing but raves from the recipients!

      I am wondering about a modification for a low-carb, low-sugar diabetic version. What do you think about changing to Aldi’s Fit&Active whipped topping (low-carb & almost sugar-free), Kroger’s CarbSmart yogurt (also low-carb, low-sugar), and no crust–just serve like a pudding?

        Sounds delicious! The only thing is that it might not thicken the same way but that would matter since you are serving it as a pudding anyway.

        I have had 61 years of Type 1 diabetes (IDDM) and switch everything I can using low carb and sugar free ingredients and it has worked out 95% of the time. Flavors are still good and nobody else in my family, including grandchildren, even care. I also switch cool whip to the light version too. You didn’t mention that but maybe just forgot? I do change a lot of desserts to the sugar free/low carb style as they still taste good. I even use a carb counter app on computer as I love to change a lot of recipes even if they don’t list the carbs on the box. One thing that I found interesting is that the carb count on regular cake mix versus sugar free cake mix is virtually almost the same! Doesn’t seem right so I think I’ll play around with a “from scratch” recipe as I know I can cut those darn carbs down! I found several low carb/low sugar recipes on line by using a search engine to locate recipes as that will mean that all the calculations/substitutions have been done and they will usually describe the end flavors. It is also nice to reciprocate if you have a good recipe too!

      I was wondering how much bottled key lime juice would you use with reg lime jello and key lime yogurt

        The bottled key lime juice just adds a little extra lime flavor to the pie, so the two teaspoons of key lime juice would work with regular lime jello and key lime yogurt. Happy Thanksgiving! ~Tonia

      When you use orange jello and vanilla yogurt do you use 2 tsp orange juice and orange food color?

        Yes, use orange jello and vanilla or orange yogurt. You can skip the orange juice and add orange food coloring if you want to make the pie more orange in color. Enjoy!

      Hi, I am on Weight Watchers and calculated the nutritional facts into my app to find out how many points a slice would be, but I noticed there wasn’t any type of serving size for the nutritional facts. What serving size were the facts meant to be for?

        Hi Natali,
        The serving size is calculated by the number of servings in the recipe shown at the top of the card. For this recipe, it is 8 servings. Enjoy!

            Hi Dawn,
            I’m not sure I understand your question correctly but you need all three: a .3 oz package of sugar-free lime jello, 2 tsp key lime juice, and 12 oz light key lime pie flavored yogurt.
            Enjoy,

      I substituted Aldi’s Greek Key Lime Pie yogurt, fresh squeezed Mexican lime juice, and lime wedges for garnish because I’m too old & trembly to make those nice citrus peels.
      No food coloring added because the gelatin & yogurt were plenty green.
      My bride is a key lime pie connoisseur & devotee…when she says it passes muster, I know it’s excellent.
      Enjoy.

      If you are really in a hurry, just fold together the 2 containers of yogurt and one container of Cool Whip, spread it into the pie crust and freeze for a couple hours or over night. Cut when frozen, slightly microwave each piece before serving.
