Tiny Chocolate Cones

(Microwave 700 watts). To make the cones:- Cut twenty-five 9cm foil squares. Fold each diagonally in half to make a triangle. Hold each triangle with the long side towards you. Bring lower right point over to meet top point. Roll left side of foil around right side to form a cone with a tight point at the bottom; secure with tape. Repeat with the other squares. Place chocolate and butter in a medium bowl. Heat, covered on HIGH 2 - 2 1/2 minutes, or until melted. Remove from microwave and stir until smooth. Stir in cream and vanilla. Set the bowl over iced water; beat mixture until fluffy. Fold in nuts, keeping 1 Tbsp. Spoon the mixture in a piping bag fitted with a medium star tube; pipe into foil cones. Sprinkle with reserved nuts. Put in the refrigerator for a least 1 hour or until set.
