Cut 6 inch circles from wax paper; cut in half and shape into cones; secure
edges with tape.
Place dark chocolate into a pan and melt, let cool until slightly thickened,
then transfer to a ziploc bag. Make a tiny hole in the bottom corner, and
drizzle a bit into the lower 2 inches of the cone. Let cool completely.
Melt white chocolate, and cool until slightly thickened. Brush a thin
layer over chocolate layer in cones, making sure to get the bottom of the
cone. Chill until firm.

light and fluffy. Add liquer, beating at medium speed until combined.
Add whipping craem to liquer mixture. Place mixture into a pastry bag and
pipe into cones. Chill until firm and ready to serve.
