Have you made gingerbread houses with your kids? I used to do this every year when my son was young, and even as he grew up, he still wanted to join in with my young nieces... lots of fun!!
I would start with a gingerbread house kit for each (you can buy many places for about $10). I would assemble them ahead of time and secure them on a piece of foam core. We wouldn’t just decorate the houses, but rather make whole scenes. I would buy additional candies, cookies, Santa wrapped chocolates, etc. One rule... everything had to be edible, so I would make a paste out of confectioners sugar and water, put it in a pastry tube and that would be our glue. Those Keebler fudge logs are great for chimneys with a chocolate wrapped Santa going in or on a sleigh. We had decorated pathways and trees along the way. After all decorated, I would spread a thin layer of that sugar paste and we would fill with mini marshmallows for snow.
Everyone proudly enjoyed viewing their creations the days leading up to Christmas!!
