We made it to the end of Popsicle Week! Which recipe has been your favorite flavor so far?

Today’s popsicle is maybe my favorite of the whole bunch: Key Lime Pie Popsicles!

These healthy key lime pie popsicles have all the favor I love in classic key lime pie (a fresh, sweet-tart filling + graham cracker crust), but here we’ll turn it into a creamy key lime pie smoothie and swirl in graham cracker “crust” crumbles. The end result is DELICIOUS.

While most of the popsicles in this week’s lineup fall clearly into the “fun, healthy snack” category, our key lime pie popsicles lean a bit more toward “healthy treat.” We LOVE them so much on a hot day! And, just like our other homemade popsicle recipes, these key lime pie popsicles are SUPER easy to make.

Here’s what you’ll need to get started on this tangy lime popsicle recipe…

HERE’S WHAT GOES INTO OUR HEALTHY KEY LIME PIE POPSICLES:

  • Plain Yogurt (Dairy-Free or Dairy). To start our key lime pie popsicles, we’ll start with a base of plain yogurt. Dairy-free and dairy yogurts all work for this recipe. (Scroll down to see some of our favorite dairy-free options if you need them!)
  • Coconut Milk. Next up is some coconut milk. I recommend full-fat canned coconut milk here to ensure that your lime popsicles have a velvety, creamy texture. If you use low-fat/lite or the chilled coconut milks that come in cartons, your pops will be more icy than creamy.
  • Fresh Lime Juice. I work a double dose of lime flavor into these lime popsicles, and that starts with fresh lime juice. Bottled lime juice will NOT work here, as it’ll add a sharp and bitter taste. Fresh only, please. Also, you can use traditional limes or key limes. (I can only rarely find key limes where I live.)
  • Honey or Agave. Just like with key lime pie, we want to strike the balance of sweet + tart. We’ll take the edge off the tartness of the lime juice with honey or agave. You can trust your tastebuds here, so if you want to start with less sweetener or need to add more, go for it!
  • Lime Zest. Next is lime zest. You’ll get concentrated lime flavor from the natural oils in the peel here, which makes for the BEST flavor! I recommend a microplane zester for getting your lime zest. Remember not to get the white pith! You only want the green peel.
  • Vanilla Extract. A splash of vanilla makes these almost taste like ice cream. I love it!
  • Graham Crackers + Butter or Vegan Butter. For the graham cracker crumbles, you’ll crush up some graham crackers and mix them with butter or vegan butter. I LOVE this textural contrast SO MUCH.

A POPSICLE MOLD! You’ll also need a popsicle mold (or some paper cups) and popsicle sticks to make these key lime popsicles. We highly recommend this popsicle mold.

HOW TO MAKE POPSICLES WITHOUT A POPSICLE MOLD:

If you don’t have a popsicle mold or can’t get one (I get it!), here’s how to make a popsicle in a cup:

  1. Set out 3 oz. paper cups (they work best) or small plastic/melamine cups.
  2. Fill the cups with your popsicle mixture as directed (you’ll need to adjust a bit for size), leaving a bit of room for the popsicles to expand in the freezer.
  3. Cover the cups with foil and insert a popsicle stick. (The foil keeps the sticks in place)
  4. Place cups on a cutting board, tray, or plate for stability and freeze as directed. (Remember that your popsicles may take longer to freeze depending on how wide & deep your cups are.)
  5. When they’re frozen, remove the foil and peel away the paper cup! (Or run the outside of a plastic cup under cold water for a few seconds to loosen and wiggle the stick side to side to remove it from the cup.)

GLUTEN-FREE + DAIRY-FREE + VEGAN OPTIONS FOR THESE KEY LIME POPS:

GLUTEN-FREE GRAHAM CRACKERS:

DAIRY-FREE & VEGAN YOGURT:

  • Culina, CoYo, and So Delicious, are 3 of our favorite brands, but brands like Chobani, Yoplait, and Siggi’s all have dairy-free options these days!

FAQ + TIPS AND TRICKS FOR THE BEST KEY LIME PIE POPSICLES:

THE BEST POPSICLE MOLD. We’ve tried lots of molds over the years, but we think this popsicle mold by Norpro is the best. It has 10 slots, sturdy construction (so it stays upright better in the freezer!) and has a lid to hold the sticks in place. It also comes in silicone versions, but I find these can sometimes hold onto scents and flavors.

HOW TO GET POPSICLES OUT OF THE POPSICLE MOLD: Run each well of your popsicle mold under cold water for a few seconds, then jiggle the sticks side to side to loosen the pops. (Run the mold under water again if they’re still not loosening.)

CAN I USE REGULAR LIMES INSTEAD OF KEY LIMES? I basically always do, and most commercially-made key lime pies actually use traditional limes instead of key limes these days. I know that it’s technically just “lime pie popsicles” if I’m not using key limes, but I know not everyone has access to key limes. If you can find them, use them! If not, feel free to use traditional limes.

WHAT ARE YOUR FAVORITE GLUTEN-FREE GRAHAM CRACKERS? I’ve got a big list in this post of our favorite store-bought gluten-free snacks! I’ve also linked our favorites in the section above this one.

WHAT ARE THE BEST VEGAN GRAHAM CRACKERS? This list of vegan graham crackers is really helpful whether you’re gluten-free & vegan or just vegan. If you need gluten-free AND vegan graham crackers, we recommend Kinnikinnick or Nairns. You can also make your own!

  • Diet: Gluten Free

Description

Key Lime Pie Popsicles – These creamy lime popsicles taste like a slice of your favorite key lime pie! Made from healthy ingredients, they’re the perfect summer treat! (Gluten-Free & Vegan-Friendly)

*Pro tip: zest your limes before you juice them!


Ingredients

Scale

FOR THE KEY LIME PIE POPSICLE MIXTURE:

  • 1 1/2 cups plain yogurt (dairy-free or dairy, as needed)
  • 2/3 cup coconut milk (I recommend full-fat for the best texture)
  • 1/3 cup fresh lime juice (from about 3 limes) or 23 Tbsp. key lime juice (from 69 key limes)
  • 1/2 cup honey or agave (use agave for vegan)
  • 1 Tbsp. fresh lime zest* (try to get only the green peel not the white pith)
  • 1 tsp. vanilla extract

FOR THE GRAHAM MIXTURE:

  • 2 Tbsp. butter or vegan butter, melted
  • 5 sheets of graham crackers (about 87 g.), gluten-free/vegan, as needed

*OPTIONAL: Additional lime zest for garnish


Instructions

FOR THE POPSICLE MIXTURE:

  1. In a blender, combine yogurt, coconut milk, lime juice, honey or agave, lime zest, and vanilla.
  2. Blend until smooth and the honey/agave is well incorporated. (You also want the lime zest to break down quite a bit here to flavor the mixture more fully)
  3. Taste and add additional sweetener, if needed. (It should be fairly tart & sweet to mimic the flavor of key lime pie.)

FOR THE GRAHAM MIXTURE:

  1. Place the graham crackers in a large bowl and use the back of a cup to crush them into small (but not miniscule!) pieces. I like having a few larger pieces and some smaller pieces. You can also do this by placing the graham crackers in a bag and using a cup or a rolling pin to crush them.
  2. If you haven’t already, melt the butter in a microwave-safe dish for 10-20 seconds at a time, until it’s fully melted.
  3. Add the butter to the crushed graham crackers and use a fork to coat the crumbs well with the butter. Little clumps will start to form.

TO ASSEMBLE YOUR POPSICLES:

  1. To assemble your popsicles, fill each well of your popsicle mold halfway full with the smoothie mixture.
  2. Add 1 tsp. graham cracker crumbs to the popsicle mold. Swirl or poke the crumbs down with a popsicle stick a bit (if desired).
  3. Fill the popsicle mold almost all the way to the top, leaving about 1/4″ space.
  4. Add another teaspoon of graham cracker crumps to the top. (This will become the bottom of the pops once they’re removed from the popsicle mold.)
  5. If you have any additional graham crumbs, you can save them for garnish!
  6. Cover the popsicle mold with a lid or wrap tightly with foil and insert the popsicle sticks.
  7. Place on a level surface in the freezer and freeze at least 4-5 hours, or until completely solid.
  8. To remove popsicles from the ice pop molds, remove the lid and run each well of the popsicle mold under cold water for a few seconds. Gently wiggle the popsicle stick side to side to help loosen the popsicle from the mold. (If it’s not budging, just run it under cold water for a few more seconds and try again)
  9. If desired, sprinkle additional lime zest or any leftover graham crumbs onto the popsicles for garnish & enjoy!
  10. Store frozen popsicles in an airtight freezer-safe bag for up to 2 weeks.

Notes

TRUST YOUR TASTEBUDS. Like traditional key lime pie, these key lime pie popsicles are meant to strike just the right balance between sweet and tart. If you want to start with less lime juice or add more sweetener, feel free to follow your tastebuds!
