{Guiltless} Key Lime Pie

keylimepieeeKey Lime Pie fans — or KLPF for short — rejoice.  Y’all have a guiltless version of your favorite treat starting now.

I am a recent convert of KLP.  While it’s not my favorite pie flavor, and I certainly wouldn’t choose it over say, apple or coconut cream, I do like it.  I like that tangy, sour bite and the creamy texture.  And I like limes, but usually only in margaritas, so it’s nice to enjoy them in something other than straight tequila and my depressing company of drinking alone.

And it’s only fitting I fall in love with KLP now because I’m headed to Miami next month for BlogHer Food and I have a pretty decent hunch that this particular pie is pretty darn popular down there.  Needless to say, I’m stoked to have a taste of an authentic Key West Key Lime Pie!

In the meantime, and because I live approximately a billion miles away from Florida, I need something easy to whip up when I get lonely and tequila isn’t an option (which, let’s face it, tequila is never really a decent option to begin with).  So I whipped up this Guiltless Key Lime Pie and whoa, y’all.  This is the cure for what ails your te-keeel-ya heart.

DSC_0063AYou will never believe this creamy, tart pie is made with lightened up, smarter substitute swaps and isn’t loaded with a billion calories or fat grams.  It’s light, fluffy, easy to prepare, and tastes pretty darned close to the real thing.

And if you don’t think so, well, try drinking a shot first and then get back to me.  Bottoms up!!

Recipe type: Pie

Total time: 
Serves: 8
Love the tangy taste of key lime pie but hate the overload in calories? It's time to meet your new favorite KLP fix: this Guiltless version, which tastes every bit as creamy, tangy and dreamy as its usual counterpart!
  • 1 9" prepared low-fat graham cracker pie crust
  • 1 (14 oz) can fat free sweetened condensed milk
  • ½ cup key lime juice
  • ½ cup fat free sour cream
  • ¼ cup fat free liquid egg substitute
  • Zest of 2 limes
  • Cool Whip Free
  • Lime slices, for garnish (optional)
  1. Preheat oven to 350 degrees F. Place the prepared pie crust onto a rimmed baking sheet and set aside.
  2. In a large bowl, combine the condensed milk, lime juice, and sour cream. Whisk thoroughly until smooth. Add in the egg substitute and lime zest and mix until combined.
  3. Spread the filling into the prepared pie crust. Bake for approx. 15 minutes or until edges are firm. Do not over bake! Allow the pie to cool completely.
  4. Once cooled, refrigerate the pie until chilled, about 2 hours. Just before serving, garnish each slice with a healthy dollop of Cool Whip Free and garnish with a lime slice, if desired.

DSC_0065AI took this pie to a friend’s house and it was devoured by her family in seconds.  No one realized this tart and delicious pie was guiltless until I told them so.  The texture and bright, refreshing lime flavor is so spot-on that no one will know your little low-cal secret.  This pie will be a huge hit at your next gathering, I just know it — and if not, again — that’s what the tequila is for 😉

Have a delicious day!

  1. I am in loooooove. We MUST find the best pie in Miami. I’m willing to try 100 to find it. 🙂

  2. I need to try key lime pie already! This looks awesome!

  3. I lived in Miami for 6 months and yes – there is amazing key lime pie everywhere (that was actually the first time I had key lime pie was in Miami). I need this is my life!!

  4. Hayley, you know this is right up my alley!! All those lighter swaps = perfect. I’ve actually never had true key lime pie — only the flavored Yoplait yogurt — but with how creamy yours looks, I think it’s about time that changed. And ohmygosh Miami is only 2 weeks away!! Where did the time go??? Can’t wait to see you there!!

  5. I am loving the Guilt Free dessert swaps! This looks beautiful and soooo delish! Perfect for a summer BBQ!

  6. Um, must make. And soon. And will eat all by myself. You can’t stop me!

  7. First off – WHERE did you find limes that look like that?! Seriously, I cannot find a decent lime in GA to save my life. And the ones I did find? They were hard as rocks and 2 for $3.00!!! Evil.

    Because I need to make this pie! And how am I going to do that without limes?!! Noo!!! Life is so cruel!

  8. I usually ignore my guilt when it comes to keylime pie but you are making it easier to down an entire dish 🙂

  9. yeah ok well I just met my new favorite summer dessert. I MUST EAT IT ALL!! 😀

  10. Excellent, what a website it is! This website provides
    helpful information to us, keep it up.

  11. This sounds amazingly delishious!!! I’m from Florida so I love Key Lime pie! I love the idea of a low cal version. Do you have nutritional info for this? Thanks so much! Love your blog!:)

      Hi Patti! Unfortunately I do not have nutritional info on this recipe. I did get the recipe from Hungry Girl so perhaps she has stats on her site or in her books. Sorry I don’t have the info for you, but I hope you enjoy!

  12. This pie looks really good. I did make it and it’s chillin’ in the fridge as I type this. I’m excited to try it. I would not call this pie a “guiltless” pie at all. When I entered the ingredients on myfitness pal and created the recipe the calories and sugars were very high! 350 calories and 35g of sugar for 1/8 of the pie. It is probably better than a traditional Key Lime pie recipe but not something you should eat on a regular basis!
