Prepare the Vegan Ladyfingers: Preheat oven to 350F (175C). In a bowl, whisk together flour, baking powder, and salt. In a separate bowl, whisk together sugar, oil, plant-based milk, and vanilla extract. Add the wet ingredients to the dry ingredients and mix until just combined.
Line a baking sheet with parchment paper. Pour the batter onto the baking sheet and spread evenly. Bake for 15-20 minutes, or until a toothpick inserted into the center comes out clean. Let cool completely, then cut into ladyfinger shapes (approximately 3-4 inches long).
Prepare the Matcha Soak: In a bowl, whisk together hot water, matcha powder, and sugar (if using) until the matcha powder is completely dissolved. Set aside to cool slightly.
Prepare the Matcha Cream: In a high-speed blender, combine soaked cashews, coconut cream, plant-based milk, maple syrup, matcha powder, vanilla extract, and salt. Blend until completely smooth and creamy. If the mixture is too thick, add a little more plant-based milk until it reaches the desired consistency.
Assemble the Tiramisu: Dip each vegan ladyfinger into the matcha soak for a few seconds on each side (do not over-soak, or they will become soggy).
In a serving dish, layer the soaked ladyfingers along the bottom. Spread a layer of matcha cream over the ladyfingers.
Repeat layers of soaked ladyfingers and matcha cream until all ingredients are used, ending with a layer of matcha cream on top.
Cover the dish and refrigerate for at least 4 hours, or preferably overnight, to allow the flavors to meld and the tiramisu to set.
Before Serving: Dust the top of the tiramisu with matcha powder. Slice and serve chilled.
Optional Tips:
For a stronger matcha flavor: Increase the amount of matcha powder in the cream and soak.
For a richer cream: Use more coconut cream and less plant-based milk.
Vegan Ladyfinger Substitution: Use vegan biscotti for a crunchier texture, but adjust the soaking time accordingly.
If you do not have time to bake your own ladyfingers: Purchase vegan-friendly cookies and cut them into strips.
