Things you’ll need:
-4 inch CookieCutterKingdom Caboose Train Cutter
-Shortbread cookie dough
-Royal Icing in red, blue, and gray
-Piping bags fitted with tip #3 (or try Tipless Piping Bags. Simply cut the tip size you want and discard the bag when you're done. No need for clean up!)
Roll out your dough, cut out the train shapes, freeze them for about an hour, bake at 350, and cool completely.
Pipe your blue and gray areas first: the wheels, the chimney, the window, etc. Let them dry for about 15 minutes. Then pipe the red areas. Let them dry for at least an hour, or overnight.
Once the red areas are all dry, outline the window in blue again. Then outline the wheels in gray, adding detail to the “cattle catcher” (the front of the train - I had to look that up!).
Wrap them individually with ribbon for favors at any transportation-loving kid’s party!
