Line an 8-inch square baking pan with parchment paper, and lightly grease with coconut oil.
In the work bowl of a food processor, place dates. Pulse until finely chopped. Add pecans, ground ginger, cinnamon, and salt; pulse on medium-low speed until a sticky dough begins to forms, with small pecan bits remaining. (Do not overprocess or the dough will become oily.) Press dough into the bottom of prepared pan.
1 cup (150g) pitted Medjool dates, 1½ cups (170g) raw pecans, ½ teaspoon ground ginger, ½ teaspoon ground cinnamon, ¼ teaspoon kosher salt
Drain soaked cashews, and rinse with cold water. In the container of a blender, combine cashews, coconut milk, maple syrup, melted coconut oil, molasses, lemon zest and juice, vanilla, nutmeg, cloves, 1½ teaspoons ginger, 1 teaspoon cinnamon, and ¼ teaspoon salt; blend until mixture is silky smooth and creamy, 2 to 3 minutes. Taste and adjust seasonings, if desired.
2 cups (284g) unsalted raw cashews, ½ cup (120g) full-fat coconut milk, ⅓ cup (113g) pure maple syrup, ¼ cup (56g) refined coconut oil, 3 tablespoons (63g) unsulphured molasses, ½ teaspoon (1.5g) lemon zest, 2 tablespoons (30g) fresh lemon juice, 1 tablespoon (13g) vanilla extract, 1½ teaspoons ground ginger, 1 teaspoon ground cinnamon, 1 teaspoon grated fresh nutmeg, ¼ teaspoon ground cloves, ¼ teaspoon kosher salt
Pour filling into prepared crust, smoothing top with an offset spatula. Tap pan on the counter a few times to release any air bubbles. Freeze until completely firm, at least 3 hours.
When the cheesecake bars are set, run a knife under hot water to warm it up before cutting bars with the still-hot (dried) knife. Cut into 16 squares. Garnish with cinnamon, nutmeg, and pecan halves, if desired.
Garnish: ground cinnamon
Let thaw at room temperature for 10 to 15 minutes before serving.
Refrigerate in an airtight container for up to 2 weeks, or freeze for up to 2 months.
