Add 1tsp pink gel food colouring to 1/4 of the royal icing. Make sure to keep the royal icing covered in the bowl to stop it from hardening.
Use a spoon to add some of the royal icing on to the top of the cake. Spread all over the cake using a spatula. Spread the pink royal icing around the bottom half of the cake. Smooth using a cake scraper.
Put the cake in the fridge until the royal icing has completely hardened before placing the gingerbread house on top.
After placing the gingerbread house on top, use the left over royal icing from the gingerbread house to pipe icicles around the top of the cake, and around the gingerbread house to create a snow effect.
