Ingredients You’ll Need
- 1 1/2 cups Biscoff cookie crumbs or honey-free graham crackers: These provide a rich, buttery flavor to the crust. For a gluten-free option, use gluten-free graham crackers.
- 3 tablespoons granulated sugar: This sweetens the crust without overpowering it.
- 6 tablespoons vegan butter, melted: This helps bind the cookie crumbs together to create a perfect crust. Coconut oil can be a workable substitute here.
- 1 (11.25 ounce) can coconut or oat sweetened condensed milk or homemade: This creamy base is crucial for that luscious filling. You can also use any plant-based condensed milk you prefer.
- 10.8 ounces Mori Nu silken tofu, drained: This adds creaminess and helps bind the filling without any eggs. Make sure to use silken for the right texture.
- 1 cup granulated sugar: This balances the tartness of the lime juice.
- 3 tablespoons lime zest: Zesting adds an aromatic and vibrant flavor that intensifies the overall taste.
- 2/3 cup fresh lime juice, preferably key limes: Fresh juice is key for that authentic zesty flavor—bottled juice won’t give the same punch.
- 4 tablespoons cornstarch: This thickens the filling, ensuring it sets beautifully once cooled.
How to Make Vegan Key Lime Pie Bars
Prepare Biscoff Crust: Preheat the 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 until it resembles moist crumbs. Press the mixture firmly into a parchment paper-lined 8-inch square baking pan, and bake for about 10 minutes. Remove it from the oven and set it aside to cool.
Make the Key Lime Filling: In a blender or food processor, combine 1 can of sweetened condensed milk, 10.8 ounces of drained Mori Nu silken tofu, 1 cup granulated sugar, 3 tablespoons lime zest, 2/3 cup fresh lime juice, and 4 tablespoons cornstarch. Blend until smooth. Then, pour the mixture into a medium saucepan and bring it to a gentle boil over medium-high heat. Whisk constantly until the mixture thickens, which should take about 5-7 minutes. Remove it from the heat.
Pour Filling on Crust and Set: Carefully pour the thickened filling over the cooled crust. Allow it to cool at room temperature for about 30 minutes. Afterward, refrigerate for at least 3 hours or until completely set.
Serve: Once cooled and set, slice the bars and serve with a dollop of vegan whipped cream on top. A little extra lime zest sprinkled on top gives them an inviting touch.
Storing & Reheating
To keep your Vegan Key Lime Pie Bars fresh, store them in an airtight container in the refrigerator for up to 5 days. If you have leftovers and want to keep them longer, you can freeze the bars for up to 3 months. Just ensure they are wrapped well to prevent freezer burn. When ready to enjoy, simply thaw them in the fridge overnight; a quick slice in the microwave (about 10 seconds) can help restore their creamy texture!
Chef’s Helpful Tips
- Avoid cracking your filling by not overcooking it; whisk it constantly as it thickens to ensure a smooth texture.
- For the best results, use fresh key limes if you can find them, as they give a unique flavor that bottled juice can’t replicate.
- If you’re using a different brand of silken tofu, or a different type, be sure to check for blending consistency.
- Experiment with topping options, like coconut whipped cream or fresh fruits for added flavor and texture.
These bars are not only a treat for the eyes but also a deliciously creamy indulgence. The vibrant lime flavor combined with the luscious texture is simply irresistible!

Recipe FAQs
Can I use regular tofu instead of silken tofu?
Yes, but using silken tofu is recommended for the creamy texture needed in the filling. Regular tofu is more dense and may result in a different texture. If you have to use regular tofu, blend it until smooth and consider adding a splash more sweetened condensed milk to achieve a creamier consistency.
How do I make this gluten-free?
To make Vegan Key Lime Pie Bars gluten-free, simply substitute the Biscoff cookie crumbs with gluten-free graham crackers or other gluten-free cookies. There are many great options available that will provide a similar taste and texture.
Can I use other citrus fruits instead of lime?
Definitely! While key limes bring a unique flavor, you can use regular limes, lemons, or even a combination of citrus fruits for a creative twist. Just remember to adjust the sweetness slightly if the fruit is more tart.
How long do these bars need to chill before serving?
For the best results, allow the bars to chill in the refrigerator for at least 3 hours, or ideally overnight. This helps the filling set properly and intensifies the flavor, ensuring a refreshing treat when you’re ready to serve.
