In a separate bowl, combine coffee and liqueur. Add 3 tablespoons of the coffee mixture to the cream mixture. Dip one side of each ladyfinger into remaining coffee and layer sides and bottom of a 9-inch loaf pan with the lady fingers. Spread cream mixture over ladyfingers. Dust with half the cocoa powder. Dip remaining ladyfingers in coffee and layer on top of cream. Dust with remaining cocoa powder. Chill for 2 to 3 hours or until set. Decorate with strawberries  drizzled with white chocolate.
