Ingredients

Crust

  • 1 ⅔ cups finely crushed Simple Mills Sweet Thins or gluten free graham crackers of choice. It should be as fine as sand.
  • 5 tbsp butter sub vegan butter if preferred
  • ¼ cup coconut sugar

Filling

  • 2 14-oz cans organic sweetened condensed milk
  • 1 cup plain non-fat Greek yogurt
  • 2 tsp lime zest
  • ¾ cup lime juice

Topping

  • 1.5 cups organic heavy whipping cream can sub coconut cream (the thick part of cans of coconut milk) or use dairy free whipped topping of choice instead
  • 3 tsp granulated sugar
  • 1 tsp vanilla extract
  • 8-10 slices of lime for topping
  • lime zest for topping

Instructions

  • Preheat oven to 375.
  • Combine the ground Sweet Thins, butter, and coconut sugar in a bowl and mix with a fork until it forms a sand-like consistency.
  • Spray a 9-inch porcelain pie pan (I used a white one) with avocado oil. Press the crust down into the pan using the back of a measuring cup, making sure to go up the sides. It should be about 1/4 - 1/3 inch thick. Bake for 10 minutes.
  • Combine the filling ingredients in a bowl and whisk until combined. Pour it into the warm pie crust once it comes out of the oven.
  • Turn the oven temperature down to 350 and bake the pie with the filling for 15-18 minutes.
  • Let it cool for 30 mins at room temp, then transfer to the fridge for at least 3 hours up to overnight. 
  • Right before you're ready to serve the pie, make the topping.
  • Add the heavy whipping cream (or coconut cream) to a bowl and beat using a hand mixer until stiff peaks begin to form. Add in the sugar and vanilla and continue mixing until it is light and fluffy.
  • Spoon the topping onto the pie, add lime slices and zest for decoration, and serve! Enjoy!

Notes

Expert Tips

  • Make sure to let the pie cool at room temperature for 30 minutes and then chill completely in the refrigerator for 3 hours; otherwise, the consistency might be too soft. It's even better when you let it sit overnight and top it with whipped cream the next day!
  • If you're looking to make a dairy-free or vegan key lime pie, unfortunately, this is not the recipe to make, as the substitutions cause it to turn out very watery. I do, however, have a dairy-free vegan key lime pie bar recipe that can be made into a pie!

Storage Tips

  • Store leftover pie covered in plastic wrap or transferred to an airtight container in the refrigerator for up to 4 days. Serve chilled with a spoonful of whipped topping, and enjoy! 
  • Any extra whipped cream can be stored in the fridge in the bowl for up to 4 days. You may need to re-whip it before serving, as it can get watery.
