Open the chilled cans of coconut milk and scoop the solid cream into a large mixing bowl. Save the coconut water for a smoothie or discard it. Add the powdered sugar or powdered Erythritol.
Use an electric hand mixer to beat the mixture until light and fluffy. Refrigerate.
Add the soaked cashews, plant-based milk, maple syrup, vanilla extract, and pinch of salt to a blender and blend until completely smooth and creamy, scraping down the sides of the container if needed.
Gently fold the cashew cream into the whipped coconut cream using a spatula. Set aside.
Assemble
In a medium-sized bowl, combine chilled coffee with coffee liqueur.
Lightly press one side of a cake slice to the top of the coffee and remove immediately or use a brush to brush coffee over the cake slices in the pan. Repeat with more cake strips to cover the surface. I used an 8″ (20 cm) square dish that gets slightly wider at the top, you could also use a 9″ (23 cm) square dish or a rectangular one around 10.5 x 6.6 (27 x 17 cm) and at least 3 inches (8 cm) in height.
Spread about half of the mascarpone cream evenly over the cake strips. Add another layer of soaked cake slices, and top with the remaining mascarpone cream. You may have some leftover cake pieces that you can eat plain.
Cover the baking pan with plastic wrap and place it in the refrigerator for 3 hours or overnight.
Finally, dust with cocoa powder and serve. Enjoy!
Notes
Vanilla Cake: You can use store-bought ladyfingers that fit your dietary needs, instead of making the cake. However, if you want to make the vanilla cake and are not gluten-free, you might be able to use regular all-purpose flour or spelt flour.
Cashews: Soak cashews in cold water for about 3 hours (or overnight) or in boiling water for about 20-30 minutes. If you can’t have cashews, you could try using vegan cream cheese to replace the cashews and the milk (I haven’t tried it in this recipe though).
Coffee liqueur: You can use rum instead, or use 1 tbsp maple syrup and add some drops of rum flavor.
