How to Make Vegan Key Lime Pie Bars
Prepare Biscoff Crust: Preheat your oven to 350 degrees F. In a medium bowl, mix together 1 1/2 cups Biscoff cookie crumbs, 3 tablespoons granulated sugar, and 6 tablespoons melted vegan butter until it resembles moist sand. Press this mixture firmly into a parchment-lined 8-inch square baking pan. Bake for 10 minutes, until set. Remove from the oven and let it cool slightly.
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 Mori Nu silken tofu, 1 cup granulated sugar, 3 tablespoons lime zest, 2/3 cup fresh lime juice, and 4 tablespoons cornstarch. Blend until completely smooth and creamy. Pour the mixture into a medium saucepan and heat over medium-high heat, whisking continually until it reaches a boil and thickens. Remove from heat.
Pour Filling on Crust and Set: Carefully pour the lime filling over your baked crust. Let it cool at room temperature for about 30 minutes. Afterwards, refrigerate the bars for at least 3 hours, or until the filling is firm and chilled.
Serve: Once chilled, cut the Vegan Key Lime Pie Bars into squares. Top with dollops of vegan whipped cream if you like, and sprinkle with a little extra lime zest for an uplifting touch. Enjoy each slice, and watch them disappear!
Storing & Reheating
Store any leftover Vegan Key Lime Pie Bars in an airtight container in the refrigerator for up to one week. For longer storage, you can keep them in the freezer for a maximum of three months. When ready to enjoy, let them thaw in the refrigerator overnight. Their texture remains splendid without losing flavor, but topping them with freshly whipped cream just before serving helps revitalize their brightness.
Chef’s Helpful Tips
- Always drain the silken tofu well to avoid excess moisture, which can alter the filling’s texture.
- When juicing your key limes, use a citrus reamer or juicer for maximum extraction—fresh juice makes all the difference.
- For a quicker setting time, you can pop the bars in the freezer after initial cooling for about 1 hour, but allow time in the fridge before serving.
- Make sure to give the crust a thorough press into the pan to prevent it from crumbling when you cut the bars.
- You can experiment with flavor by adding a little coconut extract or vanilla for a twist on the traditional lime flavor.
These Vegan Key Lime Pie Bars offer a refreshing experience you won’t want to miss. Not only are they healthier than traditional versions, but they also bring a splash of sunshine to any gathering. There’s something wonderfully indulgent about enjoying a slice while basking in the sun, soaking in those warm rays.
