In a stand mixer, cream together the cream cheese and sugar using a paddle attachment until light and fluffy. Add in the vanilla extract and mix until combined. Set aside.
To a small cup, add in hot water and matcha, whisking to dissolve. Let cool a little.
Remove the chilled bowl from the refrigerator, and using a whisk, whip up the heavy whipping cream and powdered sugar until it reaches soft peaks.
Use a spatula to gently fold the whipped cream into the cream cheese mixture until incorporated. The mixture will become much lighter.
Carefully take a ladyfinger and dip into the matcha tea, ensuring the cookie absorbs the liquid. (Don't soak for too long or the cookie will become soggy).
Remove the ladyfinger and place onto the bottom a serving cup. Repeat with another ladyfinger until the bottom surface is covered and even.
Layer 1-2 spoonfuls of the whipped cream cheese mixture over the ladyfingers. Repeat with layering. Dust the tops with additional matcha powder.
