The night before you're going to make the tiramisu jars, place your cans of coconut milk in the fridge.
15 minutes before you're ready to begin, place the cashews in a bowl and cover with boiling water to soften them. Brew your coffee or espresso at the same time and place in the fridge to cool completely.
Drain and rinse the cashews. Add to a high-powered blender with the dairy-free milk, maple syrup, pumpkin purée, lemon juice, vanilla, pumpkin pie spice, and salt. Blend for 2 minutes until smooth and creamy. Set aside, and if there is room, place in the fridge to cool while you perform the next step.
In a large bowl, scoop out the thick white part of both coconut milk cans. It should be pretty solid after chilling. Discard the coconut water or save for another recipe. Using a hand mixer, whip the coconut milk for 2-4 minutes until air has incorporated and it is light and fluffy.
Pour the cashew mixture into the coconut milk bowl. Using a spatula, gently fold together until homogenous, being careful to not knock the air out of the whipped coconut milk.
Then it's time to layer! Grab your baking dish and begin with a layer of soaked ladyfingers. Dip the lady fingers into the cool espresso (quickly, they will absorb fast) and place on the bottom of the dish. Break pieces to fit so that the entire surface area of the dish is covered.
Then spoon a thick layer of the cream mixture on top to completely cover the lady fingers (about half the total cream amount). Repeat with another layer of ladyfingers, followed by another layer of cream until you reach the top of the dish. My 8"x8" pan fits 2 layers of each.
Cover the dish with plastic wrap or aluminum foil and place in the fridge overnight. When you are ready to serve, mix a little cinnamon into the cocoa powder and sift over the top. Slice into 9 squares and enjoy immediately!
