Healthy Coconut Key Lime Pie

This is not your typical key lime pie . . . this is sweet instead of tart, and healthy instead of unhealthy!

You know me.  I like sweet things, not tart things!  I guess that’s why I’ve never liked restaurants’ key lime pies …  along with cranberry juice, lemons, and certain apples.  Sugary sweets bring smiles to faces–smiles that reach from ear to ear.  While tart and mouth-puckering foods crumple foreheads and squeeze eyebrows together.

I vote for … the sugary sweets!  And, if you’re like me, then you will love this healthified key lime pie.

Can you guess what makes this pie green?


Hint #1:  it isn’t food coloring
Hint #2:  it isn’t key lime zest
Hint #3:  it isn’t …


Okay, I can’t hold it in any longer,  it’s spinach!  Please don’t be grossed out, you don’t taste it at all!  Spinach leaves are kind of like blueberries,  the smallest amount will provide ample color in a dish.

Perfectly smooth and deliciously creamy–other than that, this key lime pie isn’t like any other key lime pie.  Apart from being sweet and healthy, this pie is airy instead of dense  (probably due to the fact that it uses egg whites rather than egg yolks)  It has a mild flavor, with coconut and key lime undertones–neither flavor smacks you in the face with an overpowering bite.

The filling is like a mixture of mousse, jello, “restaurant” key lime pie, and whipped cream.  I usually don’t like gelatin in pies, but it wasn’t bad in this pie.  It wasn’t bouncy or jiggly, it was just like a firmer mousse, if you will.  It just melts in your mouth!  If you are the type of person who likes tart pies, roll the crust a little bit thinner than pictured and you will get more of the key lime flavor rather than graham cracker flavor.

What I am really excited about is the “graham cracker” crust, which is made without graham crackers!  The texture is like a very soft and moist cookie, or, a harder, dryer cookie dough.  There was some leftover after lining the pie pan, so I just reserved it for later (of course).  And boy, am I glad I did!  It’s like eating gingersnap or graham cracker cookie dough!

One thing to note about the crust is that it uses protein powder.  When the filling is put on top of it, the protein powder’s natural tendency is to liquify.  Don’t worry, the crust wasn’t soggy or slippery, there was just a discrepancy between the crust and filling once the pie had firmed in the refrigerator.  I know this isn’t protocol when eating pies, but I would recommend eating this with a fork and knife, sort of like how you would cut a steak (bad comparison, I know, but it’s the only one I can think of).  You can see what I’m talking about in the picture below, where the pie and crust separate a little:

But honestly, this was not a problem for me and my other happy taste-testers!  The pie will only separate when accompanied with one fork and a serious appetite (which I apparently had).

Healthy Coconut Key Lime Pie


"Graham Cracker" Crust:



  • one 12oz can Evaporated Fat Free Milk
  • 1 cup Organic Baby Spinach
  • ¾ tsp Coconut Extract
  • ¾ tsp Stevia Extract
  • 48g (¼ cup) Coconut Sugar (or dry sweetener of choice)
  • 32g (1 scoop) Vanilla Whey Protein Powder
  • 56g (¼ cup) Coconut Butter
  • 126g (6 tbs) Honey or Pure Maple Syrup
  • one 8oz tub Fat Free Cream Cheese (or ⅓ Less Fat Cream Cheese)
  • 7 Large Organic Egg Whites
  • ½ cup Key Lime Juice
  • 2 packets Unflavored Gelatin


For the Crust:

  1. Blend the oats and sucanat in blender until it becomes a fine flour, put into a large bowl. Stir in the protein powder, cinnamon and salt.
  2. Warm the coconut butter, honey and molasses in the microwave at 15-second intervals, stirring in between each one until coconut butter is melted. Pour over the dry ingredients and stir until mixture is even.
  3. Dust a flat surface and rolling pin with (GF) flour of choice and roll out the dough until it is even in height (I like thick crusts, so I didn't roll too much).
  4. Spray your deep-dish pie pan (at least 2" deep) with cooking spray and dust with more flour. Place the crust into the pan and press into the edges (reserve any extra dough for snacking). Refrigerate while you make the filling.

For the Filling:

  1. Put the evaporated milk, spinach and extracts into a blender and process until smooth. Add the coconut sugar and protein powder and blend again.
  2. Warm the coconut butter and 2 tbs of the honey in the microwave at 15-second intervals, stirring between each one, until coconut butter is melted.
  3. In a large bowl, whip together the cream cheese and melted coconut/honey mixture. Whisk in the blender mixture. Refrigerate while you complete the next steps.
  4. Put the egg whites into a bowl and the key lime juice in a separate bowl.
  5. Add the rest of the honey to a pot and sprinkle with the gelatin. Let sit for a couple minutes. Place over low heat and whisk. Once gelatin has dissolved, add the egg whites. Constantly whisk the mixture, but not vigorously. When mixture becomes thick (took me about 18 minutes) take off the heat.
  6. Very slowly, whisk in the warm egg white mixture into the refrigerated mixture. DO NOT pour it in all at once!
  7. Once the egg white mixture is added, whisk in the key lime juice. Pour this into the pie pan over the crust and refrigerate overnight.
  8. The next day, slice and serve. This pie is best eaten the day it is complete (after the overnight refrigeration), but it lasts longer.

This was my first trial (used less spinach for this one, and I kind of like the color better too):

If you would like to make a Key Lime Tart as pictured above, you will need three 4.25″x13.75″ tart pans and you will need to double the crust recipe (and roll it out lengthwise rather than into a circle).

  1. Wow! What a great way to sneak in veggies! I won’t tell anyone if you don’t!

  2. Hi! You have an interesting approach on the key lime pie here, but reading your recipe I had some queries arise from the back of my mind: how the hell can someone pasteurize egg whites?

    And stevia extract, could that be skipped or would the result be not-sweet-enough, what do you think? I know it’s a sweetener but there’s no such thing here, where I live.

    Cheers 🙂

  3. What a surprise ingredient … spinach, hmm, never would have guessed that! Thanks for hosting this giveaway!


  4. How wonderful! We never would’ve guessed spinach. Perfect idea.

    This is beautiful. We love it.

  5. Looks perfect! It reminds me of when I was in Key West, so much pie!

    Tree Surgeon-
    I mean take the whites from pasteurized eggs, or just use egg beaters, which is already pasteurized. Also, stevia is very potent and adds a lot of sweetness to the recipe. I wouldn’t omit it. You can get two large bottles for a good price on amazon, which is now linked in the recipe.
    Hope this helps!

  7. Spinach? Really?! I must give this a try. This is a fantastic veggies in disguise recipe…

  8. Looks like a tasty healthy version of key lime pie. Would love to win the giveaway!

  9. This sounds delicious, and I am curious, but a little put off by all the “healthy” ingredients I would have to purchase…I guess that would be the price one pays to have their cake and it eat it too.

  10. Nicole @ 27 & Counting and Just A Girl-
    Just thought there may have been some confusion as to which post to comment on to join the giveaway. Go to the linked post at the bottom of the page that says “click link” next to it, and it will bring you to the Apple Cinnamon Butterscotch Cake recipe post. You have to comment on that post to join the giveaway.
    Sorry about the confusion!

    If you buy certain items from, in bulk, or on sale, the price shouldn’t turn you off to this well-worth-it-pie!
    Most of my recipes use many of the same ingredients so you can try others out too 🙂

  12. You make me want spinach all the time!!!

  15. Will this work without gelatin? I’m a health-conscious vegetarian and animal bone-marrow is not something I’m willing to eat in dessert. Thanks.

    • dessertswithbenefits

      The gelatin keeps the filling firm… if you don’t want to use gelatin you should consider using agar agar powder or flakes. I have never used the powder but I have used the flakes, it works just as well!

  16. Just so you know, you didn’t mention when to add the key lime juice into the mixture >.< I was making this and was like omg…. lol but I just add the key lime juice into the refrigerate mixture and add the egg white into the whole thing later…it came out really good but I'm not sure if that is how you wanted it but yea 🙂

    It taste REALLY GOOD btw…i made a little too much filling because I make a different crust so I pour them into little muffin tin to make little pudding, taste really good too 😛

  17. Whoaaa, I was convinced this was a vegan/plant-based page! Whey protein powder and gelatin?!

    Sad to see it fall down in this respect – whey protein isn’t at all healthful, nor are egg whites. Gelatin is just unnecessary and cruel (along with the other animal ingredients).

    Not hating, but disappointed and unfortunately unsubscribing.

    • Ashley-
      I’m sorry to see you go. DWB isn’t a vegan blog, but I do make a lot of vegan, dairy-free and plant-based recipes. This recipe is actually one of my very first ones on the blog (way back from 2011)!
      I haven’t used whey protein in my recipes for quite some time. I only buy whey protein if it is organic and made from happy, grass-fed cows.
      Egg whites are incredibly good for the body, they are a complete protein source with optimum bioavailability. I only buy organic, cage-free eggs.
      Gelatin may be made from animals, but animals aren’t killed for gelatin. Gelatin is a resource that reduces waste. I buy grass-fed gelatin from humane companies.
      I do not support/buy products from major corporations that obviously abuse animals (I now buy all of my chocolate, coffee and sugar from fair-trade certified companies as well). I suffered through an entire university course on cows and cow farming practices from an actual member of MONSANTO, just so I could learn the dirty details. Now, I know exactly how cows are treated when they’re not happily grazing on open land.
      Anyways, I’m sorry to see you go. Have a great week 🙂

  18. Hello. I do not have one 12oz can Evaporated Fat Free Milk… Can I simply use milk instead?

    • Sophie-
      I’m sure regular milk will work just fine. Just note that evaporated milk is fairly thick and creamy, so I would recommend using organic whole milk or canned coconut milk.
      And 2 packets of gelatin will be ~14g or 5 tsp 🙂

  19. How many grams is two packets of gelatin?
