1. Bake Pepperidge Farm Puff Pastry Cups according to instructions.
2. When removed from oven and still warm, fill each cup with mini chocolate chips.
3. Beat marshmallow and softened butter together in mixing bowl with paddle attachment until smooth (1-2 minutes).
4. Add extracts and milk and mix well. Slowly blend in powdered sugar and beat until smooth and creamy. Add more powdered sugar if not stiff enough to pipe.
5. Use a piping bag (I used Wilton #12 tip) to pipe little ghosts! Top with 2 mini chocolate chip eyes!
