Brew 1 cup of On-the-Go Metro tea double-strength and set aside.

Mix the cream cheese, sour cream, vanilla and sugar in a mixing bowl until smooth and creamy. Pour the whipping cream into a smaller, pre-chilled bowl and beat with an electric mixer on high speed until stiff peaks form. Using a spatula, gently fold whipping cream into cream cheese mixture.

Arrange half of the ladyfingers in the bottom of a glass or ceramic loaf pan. Using a small ladle or drizzle spoon, pour half of the brewed tea over the ladyfingers to moisten them. Then spread half of the cream cheese mixture on top.

Repeat the layers, arranging remaining ladyfingers on the cream cheese layer. Soak with remaining tea, then cover with the cream cheese mixture. Sprinkle cocoa powder on top, then cover and place in the refrigerator overnight.
