Soak 1 1/4 cup of cashews in water overnight for the key lime pie filling.

Add the crust ingredients to a food processor and pulse until a sticky dough forms. Press the dough into an 8×8 baking pan lined with parchment paper. Put the crust in the fridge or freezer while you prepare the key lime filling.

Add the soaked cashews, lime juice, lime zest, maple syrup, coconut oil, coconut milk, and vanilla extract to your food process or high powered blender. Blend the filling until silky smooth and creamy.

Give the filling a taste and adjust the level of sweetness or tartness to your taste. You can add more maple syrup or add more lime juice to suit your taste buds.

Pour the key lime filling over the prepared crust. Freeze the bars overnight or until completely solid.

When you are ready to serve, remove the bars from the freezer and use a sharp knife to slice the bars into 9 or 16 pieces. Top with more lime zest and enjoy!
