Place the empty cereal box horizontally and cut both ends using a scissor. The cereal box will be the main building of the Candy Castle so it should be in good condition and should be cut in a proper manner.

Now attach the two empty paper towel rolls to either side of the cereal box with duct tape. Make sure you stick the rolls firmly as they will be the pillars of the Candy Castle. Smaller boxes can also be attached to the side of the empty paper towel rolls or on the back of the cereal box to give the castle a more authentic look.

Spread royal icing on the structure and decorate it with the help of cookies and candies. Also spread royal icing on the outer side of the cones. Now attach two cones upside down on the two empty paper towel rolls to give a proper castle look.

Attach three more cones on the top of the cereal box in the middle and stick them with the help of duct tape. Cut the tips of the cones and place three lollipops in them to give the look of spires in the castle. Continue to spread the royal icing on the remaining parts of the Candy Castle and decorate the structure according to your desire with the help of more candies and cookies.
