Follow these easy steps to build your own Christmas cookie houses:

1. Make the Icing:
   In a large bowl, sift the icing sugar and gradually mix in the milk until you achieve a thick paste. This icing will serve as the “glue” to hold your cookie houses together.
2. Build Bases:
   Spread some icing on one biscuit, then place another on top to create the base of your house. Repeat this process to make six bases.
3. Create Walls:
   Spread icing along the long edge of another biscuit and press it against a second biscuit to form a V shape. Attach this to the top of a base using icing. Repeat until you have constructed six houses.
4. Decorate:
   Use the icing to stick lollies, M&Ms, and sprinkles onto the cookie houses. Let your creativity shine as you decorate with a variety of colors and patterns.

Enjoy your festive creations! These cookie houses make for a wonderful centerpiece and a delicious treat.
