    Key lime pies are definitely one of my favorites which is why I was thrilled to make a Vegan Key Lime Pie to share.

    What is so special about key lime pie?

    Key Lime Pie is a traditional Florida dessert that has a classic tangy flavor on a graham cracker crust. We also love our Key Lime Cake.

    Why is it called key lime pie and not just lime pie?

    Because it is most commonly made with key lime juice instead of just lime juice.

    Vegan Avocado Key Lime Pie ingredients

    To make this vegan avocado key lime pie you'll need:

    • graham cracker crumbs
    • vegan butter
    • cashew nuts
    • mango
    • avocado
    • lime juice
    • full fat coconut milk
    • agave nectar
    • coconut oil

    How to make Vegan Key Lime Pie with Avocado

    1. Make the crust - In a food processor, blitz the graham crackers then add them to a bowl with the butter - mix well. Place in a pie dish and press it down to form the crust. Place in the fridge for later.
    2. Make the filling - Add the rest of the ingredients, except two limes, to a blender and blend until smooth.
    3. Fill the pie crust and chill - Pour the lime mixture into your prepared pie crust and place in the refrigerator to chill for a minimum of 4 hours (overnight is best). 
    4. Slice and garnish - Slice the pie into smaller slices, garnish with lime zest if desired, and enjoy!

    Key Lime Pie Vegan Recipe tips

    • Add more lime flavor - If you like a strong lime flavor, add in the juice of two more limes to really boost the lime flavor.
    • Skip the mango - If desired, the mango can be removed as well. It’s used for sweetness. However, you’ll want to increase the agave nectar to ¾ cup to get the proper sweetness when removing the mango.

    How to store this Vegan Avocado Key Lime Pie

    Storing: This pie can be made two days in advance and still be amazing when served. This pie will keep for 3-5 days in the fridge.

    Freezing: This key lime pie will keep in the freezer for around 3 months. Store in an airtight container for best results. Check out this post on How to Store Pies.

    Key Lime Pie Recipe Vegan FAQs

    What Is The Difference Between A Lime And A Key Lime?

    There’s not a lot of difference between a lime and a key lime. A key lime tends to be smaller, have more seeds, have a thinner skin, be a lighter green, and also seems to have a weaker tartness than a lime (also known as a Persian lime). However, the flavor is the same, although it might take a couple more key limes to really get a good flavor to a lime dessert. 

    Can you substitute limes for Key limes in key lime pie?

    Yes, the type of lime you use truly won’t matter in the overall flavor when it comes to a lime dessert. The overall flavor is the same between the various types of limes that are more popular in stores.

    Why is my key lime pie runny?

    You may not have let it set long enough or your proportions may be off.

    Why is my key lime pie crust soggy?

    Your crust may not have set enough before adding the filling or you may have left the pie at room temperature for too long.

    • Likewise with the mango but increase the agave nectar to ¾ cup for sweetness and to counteract the tartness of the lime.
