Healthy Key Lime Pie Bars! Made with a buttery oat crust that tastes like graham crackers and topped with creamy lime avocado yogurt filling for an irresistible treat! A healthier twist on key lime pie that’s made with healthier ingredients and balanced in nutrition.
Who’s ready for some summer treats? I shared these healthier key lime pie bars on Instagram before we left for Mexico over Memorial weekend. Since we got back, I’ve been secretly having a love affair with them. Creamy, cool, light and oh so good!
Lower in sugar, high in healthy monounsaturated fat and protein, key lime pie bar that actually tastes amazing and requires minimal baking. Oh yeah and they’re easy to make. Like so easy you won’t believe it. I’m so thankful I created these because I will be eating them all summer long!
Healthy Key Lime Pie
What makes these healthier? Avocados! I used a combination of avocados and Greek yogurt (Fage) to make the creamy filling. Avocados are high in monounsaturated fat. A fat that reduces cholesterol and is heart healthy. Avocados are also high in Vitamin E which is a powerful antioxidant most Americans need more of.
I’ll be the first to admit, I don’t like avocados so I’m always looking for tricky ways to add them to my diet. If you’re not a big fan either, you have nothing to worry about with these bars. You can’t taste the avocados at all! The flavor is all lime goodness!
What You Need
- Gluten Free Oat Flour
- Coconut Sugar
- Olive Oil Or Coconut Oil
- Almond Milk
- Lime Juice
- Avocado
- Greek Yogurt
- Honey
Helpful Tips
I added a touch of honey to sweeten mine, but you could always swap for powdered stevia to lower the sugar content more. For a Vegan version, swap the Greek yogurt for plain coconut yogurt.
Make sure there’s no added sugar! For Paleo, try using almond flour for the base with coconut flour. I haven’t tried it, but I am pretty sure it will work. Hope you love them!

Ingredients
For the Crust:
- 1 cup Gluten Free Oat Flour, or regular oat flour
- 2 tablespoons coconut sugar, or sugar of choice
- 1/3 cup extra virgin olive oil
- 1 tablespoon unsweetened almond milk, or milk of choice
- 1 teaspoon lime juice
- 1/4 teaspoon sea salt
For the Filling:
- 2 avocados, ripe, pitted
- 1 cup Greek yogurt, low fat
- 1/4 cup lime juice
- 1/8 cup honey
- 2 tablespoons lime juice for zesting
Instructions
- Preheat oven to 350 F. Prepare an 8-inch x 8-inch baking pan with parchment paper or grease liberally.
- In a standing mixer or using a hand mixer, blend together the oil, sugar, milk, lime juice and salt. Add the flour (measured properly) and mix together with the liquid. The dough will be crumbly at this point.
- Transfer the dough to the baking pan. Using your fingers, press it into the bottom of the pan firmly into an even layer.
- Bake at 350 F for 15 minutes until golden brown. Remove from the oven and set aside to cool 20 minutes.
- While the crust cools, prepare the filling by mixing the ingredients for the filling except the lime zest together until well combined. See notes on sugar content. Test the batter as necessary, add and combine as needed. Smooth the batter over the top of the dough and spread into an even layer.
- Place the bars in the freezer 2 hours to set. Then remove, sprinkle with lime zest and slice into 12 bars.
Notes
- Other flours have not been tested with the recipe.
- I am very sensitive to too much sugar which is why this recipe is lower in sugar. You can add more sugar to the filling as desired, but it will change the nutritional values. I recommend testing the batter to see if you need to add more.
- Keep bars in the freezer up 60 days.

Can you substitute for gluten flour? If so what kind(s)?
The recipe uses gluten free oat flour. I have not tested this recipe with any other flours. This is stated in the notes section of the recipe. You could try gluten free 1:1 baking flour, but I’m not sure what the quantity would be or how the result may differ from the oat flour.
Hi, I was wondering if these are meant to be kept in the freezer or if the fridge would work as well? Thanks!
Yes, they should be kept in the refrigerator or freezer.
I used a different crust and added 1/4 cup of maple syrup in place of 1/8 cup of honey, but the filling is excellent! Even my husband agreed that it tastes just like the key lime pies we get in Florida. Key lime pie is one of my favorites so I was so happy to find a healthier version!
YUM! I bet these are super creamy and light!
Any suggestions for a greek yogurt sub? This sounds so good!
Coconut cream (liquid discarded), coconut yogurt (look for clean-ish one without a ton of added sugar) or cottage cheese.
