- 1 (11.25 ounces) can coconut or oat sweetened condensed milk: Adds a creamy sweetness. If you prefer homemade, you can make your own using coconut milk and sugar.
- 10.8 ounces Mori Nu silken tofu, drained: Creates a silky, smooth texture for the filling. If you can’t find it, any silken tofu will work.
- 1 cup granulated sugar: Sweetens the filling and balances the tartness of the lime juice.
- 3 tablespoons lime zest: For an intense lime flavor, adding zest from fresh limes is a must.

How to Make Vegan Key Lime Pie Bars
Prepare Biscoff Crust: Start by preheating your oven to 350 degrees F. In a medium bowl, combine 1 1/2 cups Biscoff cookie crumbs, 3 tablespoons granulated sugar, and 6 tablespoons melted vegan butter. Stir until the mixture resembles moist crumbs. Press this mixture firmly into a parchment-lined 8-inch square baking pan, ensuring an even layer. Bake for about 10 minutes, then remove it from the oven and let it cool.
Make the Key Lime Filling: In a blender or food processor, combine 1 (11.25-ounce) can of sweetened condensed milk, 10.8 ounces of drained silken tofu, 1 cup granulated sugar, 3 tablespoons lime zest, 2/3 cup fresh lime juice, and 4 tablespoons cornstarch. Blend until completely smooth. Then transfer the mixture to a medium saucepan. Over medium-high heat, cook the filling, whisking constantly; bring it to a boil to thicken, which should take about 6-8 minutes. Remove from heat.
Pour Filling on Crust and Set: Carefully pour the creamy filling over the cooked crust. Allow it to cool at room temperature for about 30 minutes. Once it has cooled, transfer the baking pan to the refrigerator and chill for a minimum of 3 hours, or until fully set.
Serve: After 3 hours, the filling should be set, and the bars chilled. Slice into squares and serve with a dollop of vegan whipped cream if desired, and for an added touch, sprinkle a bit of extra lime zest on top of each square. Enjoy!
Storing & Reheating
To store your Vegan Key Lime Pie Bars, keep them in an airtight container in the refrigerator for up to one week. If you’d like to extend their shelf life, these bars can be frozen for up to 3 months. Just wrap them tightly in plastic wrap or foil before placing them in a freezer-safe container. When ready to enjoy, simply thaw them in the refrigerator overnight. Be mindful that the texture may change slightly upon freezing and thawing, but serving them chilled will refresh their flavor and texture beautifully.
Chef’s Helpful Tips
- A common mistake is over-blending the filling. Blend just until smooth to avoid a watery texture.
- Make sure all your ingredients are at room temperature to ensure a smooth blending process.
- If you find your bars too tart, you can increase the sugar in the filling a bit to balance the flavors.
- You can make the crust ahead of time and store it in the fridge until you’re ready to add the filling.
- Bake the crust on the bottom rack for a crispier base that won’t become soggy.
- For an even zestier twist, consider adding a dash of lime extract to the filling.
Don’t miss out on the punchy flavor and creamy texture of Vegan Key Lime Pie Bars. They are a perfect dessert for any occasion. Experiment with the crust and filling to find your favorite combination. Whether you are indulging on a sunny afternoon or sharing at a potluck, these bars are sure to impress. Enjoy this treat as a sweet escape!
