Ingredients You’ll Need
- 1 1/2 cups Biscoff cookie crumbs or honey-free graham crackers: These create a crunchy crust. For a gluten-free option, certified gluten-free graham crackers work beautifully.
- 3 tablespoons granulated sugar: Sweetens the crust without overwhelming it. Feel free to substitute with coconut sugar for a healthier alternative.
- 6 tablespoons vegan butter: This helps bind the crust and adds richness. You can use coconut oil if you prefer a more tropical hint.
- 1 (11.25 ounce) can coconut or oat sweetened condensed milk or homemade: This makes the filling creamy and sweet. Homemade options can use coconut milk and sugar.
- 10.8 ounces Mori Nu silken tofu, drained: Provides a smooth and creamy texture to the filling. If unavailable, try another brand of silken tofu, as texture varies.
- 1 cup granulated sugar: Essential for balancing the tart lime flavor. Use less for a less sweet option!
- 3 tablespoons lime zest: Adds vibrant flavor and aroma; key limes are ideal if you can find them.
- 2/3 cup fresh lime juice: Key to achieving that classic tangy taste. Always opt for fresh for the best flavor.
- 4 tablespoons cornstarch: Acts as a thickening agent, giving the filling a delightful creaminess as it sets.
How to Make Vegan Key Lime Pie Bars
- Prepare the Biscoff Crust: Preheat your oven to 350 degrees F. In a medium bowl, mix the 1 1/2 cups Biscoff cookie crumbs, 3 tablespoons granulated sugar, and 6 tablespoons melted vegan butter until the mixture resembles moist crumbs. Press it firmly into a parchment paper-lined 8-inch square baking pan. Bake for 10 minutes, or until the edges are lightly golden, then set aside to cool.
- Make the Key Lime Filling: In a blender or food processor, combine the 1 (11.25 ounce) can of sweetened condensed milk, 10.8 ounces drained silken tofu, 1 cup granulated sugar, 3 tablespoons lime zest, 2/3 cup fresh lime juice, and 4 tablespoons cornstarch. Blend everything until smooth and creamy. Transfer the mixture into a medium saucepan and bring it to a gentle boil over medium-high heat. Whisk continuously until the filling thickens, usually about 5-7 minutes. Remove from the heat once thickened.
- Pour Filling on Crust and Set: Carefully pour the key lime filling over the cooled crust. Let it cool at room temperature for about 30 minutes, then refrigerate for at least 3 hours until fully set.
- Serve: Once chilled and set, cut the bars into squares. Serve them topped with a dollop of vegan whipped cream and a sprinkle of lime zest for extra flair. Enjoy your delightful creation!
Storing & Reheating
Vegan Key Lime Pie Bars can be stored at room temperature for about 2 hours if serving. However, for longer freshness, refrigerate them in an airtight container for up to a week. They can also be frozen for up to three months. Just wrap them tightly in plastic wrap and then a layer of foil before placing them in the freezer. When you’re ready to enjoy, simply let them thaw in the refrigerator. The texture may change a little after freezing, but a touch of fresh lime juice drizzled before serving can revive the vibrant flavor.
Chef’s Helpful Tips
- Ensure your silken tofu is well-drained before blending to avoid a watery filling.
- When mixing your crust, pressing it down firmly ensures it holds together and doesn’t crumble when cut.
- If you prefer a thicker filling, consider adding an extra tablespoon of cornstarch.
- For a vibrant touch, use additional lime zest as a garnish to elevate the presentation.
- Make these bars ahead of time, as they taste even better when chilled overnight!
Don’t miss the chance to create this wonderful dessert that’s refreshing and indulgent! Vegan Key Lime Pie Bars not only celebrate the beauty of plant-based ingredients but also bring joy to every bite. Whether it’s a sunny day or a special occasion, these bars promise to brighten your table and your taste buds!

Recipe FAQs
Can I use other citrus fruits instead of lime?
Absolutely! While key limes are traditional, you can substitute them with regular limes, lemons, or even oranges for a unique twist. Each will provide its own flavor profile and experience!
How can I make these gluten-free?
Simply swap out Biscoff cookie crumbs for gluten-free graham crackers or any favorite gluten-free cookie base. Be sure to check that your sweetened condensed milk is also gluten-free if making it from scratch!
What can I substitute if I don’t have cornstarch?
If cornstarch isn’t available, you can use arrowroot powder or tapioca starch as alternatives. Both work well for thickening and should provide a similar texture.
How long should I chill the bars before cutting?
For best results, chill the Vegan Key Lime Pie Bars for at least 3 hours, or overnight if possible. This allows the filling to firm up beautifully, making them easier to cut into neat squares. Enjoy every refreshing bite!
