Dairy-Free Key Lime Pie Recipe

The recipe below is dairy-free and vegan.



  • 1 1/2 cups graham cracker crumbs (or crushed digestive biscuits)
  • 1/4 cup granulated sugar
  • 6 tablespoons vegan butter, melted


  • 1 cup key lime juice (fresh or bottled)
  • 14 ounces of dairy-free sweetened condensed milk (e.g., coconut milk-based condensed milk)
  • 1/2 cup silken tofu, blended until smooth
  • Grated zest of 2 key limes (optional)

Topping (optional)

  • 1 cup chilled coconut cream, whipped
  • Lime slices or zest for garnish


  • Start by preheating the oven to 350°F (175°C).
  • Mix together graham cracker crumbs, sugar, and melted vegan butter in a medium bowl. Press the mixture gently and evenly into the bottom and sides of a 9-inch pie dish.
  • Bake the crust for 8-10 minutes or until lightly golden brown. Remove and let it cool completely.
  • In a large mixing bowl, whisk together key lime juice, dairy-free sweetened condensed milk, blended silken tofu, and key lime zest (if using) until smooth and well combined.
  • Add the filling into the cooled crust and smooth the top with a spatula. Bake for 15-20 minutes or until the filling is set but still slightly jiggly in the center.
  • Remove the pie and let it cool at room temperature. Refrigerate it for at least 3 hours or overnight to set.
  • If using the optional topping, whip the chilled coconut cream until it forms soft peaks. Spread or pipe the whipped coconut cream on top of the chilled pie. Garnish with lime slices or zest as per your taste.
  • Serve the dairy-free key lime pie chilled, and enjoy!

Dairy-Free Substitutes for Making Key Lime Pie

Milk substitutes for sweetened condensed milk

Coconut milk-based sweetened condensed milk: This is a popular option because it’s thick, creamy, and has a slightly sweet flavor that complements the tartness of the key lime pie well.

Cocunut milk-based sweetened condensed milk

Almond milk-based sweetened condensed milk: This dairy-free option has a mild & nutty flavor that tastes great in a key lime pie.

Almond milk-based sweetened condensed milk

Soy milk-based sweetened condensed milk: This dairy-free alternative has a slightly thicker consistency than almond milk and can be used in key lime pie.

Soy milk-based sweetened condensed milk

Homemade sweetened condensed milk: You can make your dairy-free sweetened condensed milk using your preferred plant-based milk (e.g., oat, cashew, or rice milk) combined with sugar and a thickening agent such as cornstarch or tapioca starch.

Butter substitutes for the crust

Vegan butter or margarine: Many brands offer dairy-free butter alternatives made from a blend of oils. Choose a high-quality vegan butter with a good flavor and consistency for the best results.

Coconut oil: This can be used as a 1:1 substitute for butter in the crust. Opt for refined coconut oil to avoid any coconut flavor in your pie.

Vegetable shortening: Shortening has a similar texture to butter and can be used in the crust, but it lacks the rich flavor of butter. You can add some salt to the crust mixture to enhance the taste.

Remember that the texture and flavor of the pie may vary slightly depending on the specific dairy-free substitutes you choose.
