One day before serving, pour the cashews and coconut milk into a bowl. Scrap vanilla bean seed into the bowl. Cover and place in fridge overnight. Pour cashew mixture into a Vitamix blender. Add 1/2 cup of maple syrup. Blend until smooth an fluffy.
In a small bowl, combine graham crackers, sugar, and melted Earth Balance. Spoon graham cracker mixture into the bottom of small serving bowls (the plastic ones seen in my photos were purchased from Party America). Place a dollop of cashew-coconut milk mixture on top.
In a small pot, heat together blueberries, remaining maple syrup, cardamom, and lemon zest just until berries are hot enough to start bursting. Allow to cool before spooning on top of cheesecake. Garnish with a few fresh berries and mint, if desired.
