- Drain and rinse the soaked cashews. In a blender or food processor, combine the cashews, almond milk, maple syrup, vanilla extract, and salt. Blend until smooth and creamy. 
- In a large mixing bowl, whisk the aquafaba and granulated sugar until stiff peaks form. Gently fold in the cashew cream mixture until well combined. 
- In a separate bowl, mix the coffee or espresso and the coffee liqueur together. 
- To assemble the tiramisu, dip the ladyfingers in the coffee mixture, making sure to not soak them too much. Place a layer of ladyfingers in the bottom of an 8x8 inch dish. 
- Spread half of the cashew cream mixture over the ladyfingers. Repeat with another layer of ladyfingers and cream mixture. 
- Dust the top of the tiramisu with cocoa powder. Cover and refrigerate for at least 2 hours, or overnight, to allow the flavors to meld and the ladyfingers to soften. 
- Before serving, let the tiramisu sit at room temperature for about 15 minutes to soften. Serve and enjoy!
