Place walnuts into your food processor and pulse until they start to form a meal. Add dates and process again until everything is fully combined. Add 1 teaspoon of crust to your lined mini muffin cups. Let set in the freezer for 15 minutes.
To prepare the filling melt the coconut oil and cocoa butter in a small saucepan over low heat. Add to a high-powered blender with coconut cream, maple syrup, cashews, lemon juice, lemon essential oil (if using) and sea salt. Blend starting on low speed and slowly working up to medium and high until smooth and creamy. Add the zest of 1 lemon and starting back at low speed, blend again to incorporate.
Store in an airtight container in the fridge for up to 2 weeks or in the freezer for up to 3 months.
*Option to soak cashews in filtered water for up to 4 hours and drain before using. This step will make the cashews softer.
