In a bowl, beat the softened mascarpone cheese, 2 tablespoons icing sugar, cocoa powder and espresso powder until smooth.
Whip the cream with the remaining icing sugar and vanilla extract until soft peaks form. Fold most of it (leaving a small amount for topping) into the cheese mixture.
Divide the tiramisu dip into small glassed and top each with a small dollop of the remaining cream. Dust with cocoa powder on top. Serve with Italian lady fingers or your favorite cookies for dipping.
