First prepare the vanilla cake layers according to the recipe on that post & bake into 2- 8" square pans for approximately 25 minutes or until they are springy to the touch when you gently press the centers.
While the cake layers are baking & cooling prepare the simple syrup by combining the water & sugar together in a small sauce pot, bring to a boil then boil for 2 minutes.
Remove from heat & add the coffee granules then the Kamora.
Prepare the tiramisu cream by first preparing your favorite vegan whipped cream recipe (you will need 2 fully whipped cups) reserve in the refrigerator
Combine the sifted confectioners sugar with the vegan cream cheese in a mixing bowl & mix smooth by hand with a spatula
Slowly add the rum while mixing to combine well
Fold in the whipped cream
Trim the cake layers to fit the 8" X 8" casserole dish then soak the first layer with half of the coffee simple syrup
Spread half of the tiramisu cream over top, then add the next cake layer & the rest of the coffee syrup finishing with the remaining tiramisu cream on top
Dust with cocoa powder and optional espresso beans & refrigerate until set, preferably overnight to allow all the flavors to meld together
