Gingerbread houses? Not at my childhood home. I was born a few days after Christmas, so the birthday cake idea seemed silly after overeating from Thanksgiving through Christmas. We started making "candy houses". I think it may have started with gingerbread, but my mother didn't care for the flavor of gingerbread. It was a tradition got to help stick the candy on, with a thick fast drying icing. I got to rip the candy off and eat it on my birthday. Eventually the cardboard boxes we made the houses out of became a sturdy, wooden house, including a wooden yard, and a wooden fence, and...of course, an outhouse. (including the opening door with a crescent moon on it). One year my father brought this contraption home from his cabinet shop. It has survived all the years (40 or so) and all the candy stuck on over foil.
What is your holiday tradition that has survived?
