Heat oven to 350 degrees F. In 1-quart saucepan, melt sweet chocolate and 1/4 cup butter over low heat, stirring constantly, until smooth. Remove from heat. Stir in brown sugar, flour, liqueur and egg; set aside.
Unroll dough into 2 long rectangles; firmly press perforations to seal. Cut each rectangle in half lengthwise. Cut each half crosswise into 6 (2-inch) squares. Press or roll out each square to 2 3/4-inch square. Place 1 square in each of 24 ungreased mini muffin cups; firmly press in bottom and up side, leaving corners of dough extended over edge of each cup.
Place 1 macadamia nut in each dough-lined cup. Spoon about 2 teaspoons filling mixture over nut in each cup.
Bake 12 to 15 minutes or until filling is set and corners of dough are golden brown. Cool 5 minutes. Remove from pan; place on cooling racks. Cool completely, about 30 minutes. Refrigerate until thoroughly chilled, about 1 hour.
Meanwhile, in 1-quart saucepan, melt baking bar and cream cheese spread over low heat, stirring constantly, until smooth. Cover with plastic wrap; refrigerate until thoroughly chilled, about 1 hour, stirring occasionally.
In small bowl, beat whipping cream, powdered sugar and vanilla with electric mixer on high speed just until soft peaks form. Add chilled baking bar mixture; beat on low speed just until well blended. Pipe or spoon topping over tops of chilled cups. Refrigerate until topping is set, about 30 minutes. Store truffle cups in refrigerator.
