An edible paste dispenser for applying decorative icing to cakes and other foods includes a tip assembly that connects paste containing chambers of a dual-chamber pastry bag and directs edible paste into a common extrusion nozzle. The tip assembly includes a pair of mating tubes secured via a locking nut to the extrusion nozzle. The tubes each have a sidewall portion that is generally S-shaped in cross-section and permits stable assembly and cooperative engagement of one tube with the other tube. After insertion of a tube into each pastry bag chamber, the tubes are attached to a common extrusion nozzle. The resulting extruded paste can include two different colored decorations, which can appear swirled S or other curvilinear shape provided by the two engaged cones. The tips of the cones, and paste containing bags, terminate just above the exit portal of the common nozzle.
