Sprinkles make everything more fun, even your holiday gingerbread house. For ease, start with a pre-assembled house; all the icing, bags and tips you’ll need are included with the kit. Adding rainbow nonpareils turns this iconic holiday centerpiece into a kaleidoscope of color.
Attach sprinkles to roof. With spatula, spread a thin coat of piping gel on roof panel; sprinkle rainbow nonpareils and press to adhere. Repeat on second roof panel.
Attach sprinkles to house. Working on one section of house at a time, spread piping gel on front, back and sides of house, avoiding front door area; sprinkle nonpareils and press to adhere.
Decorate roof. Fill disposable decorating bag with tip and icing. Divide each roof panel into fourths; pipe 5 rows of scallops, about ½ in. deep. Repeat on second roof panel. Pipe zigzags on roof peak.
Decorate house front. Outline and fill in arched front door, about 1 in. wide x 1¼ in. tall; smooth with spatula. Outline door; pipe dot for door knob. Outline 1 in. square windows above and on either side of door; add lines for window panes.
Decorate windows on sides of house. Outline a 2 3/4 in. wide x 1 in. tall window on both sides of house; add lines for window panes.
