In the bowl of an electric mixer, combine cream cheese, sour cream, sugar, and vanilla. Whip until combined.

Add a brownie square or two to the glass. Pipe or spoon a cream layer on top. Spoon a teaspoon of espresso over the brownies. Add more brownie squares, cream, and coffee. End with a cream layer and garnish with a meringue.
