In December Kottkamp shifts her focus to elaborate gingerbread houses. These aren't cottages decorated with gumdrops. Kottkamp's elegant creations have featured stained-glass windows, a skating rink, and a mountain dotted with marzipan skiers. One house, made for Bethesda's Holton-Arms School, featured rooms–visible through the tiny windows–furnished with a candelabrum, fireplace, and bookshelves. Cakes start at $50, houses at $50.
