We had a spent a wonderful morning making gingerbread houses with out friends. Well to be honest we made the actual houses the day before and decorated them the next day. My friend's children are allergic to milk and eggs so we used a vegan recipe for both the gingerbread and the icing. I think they turned out great! Here is her website that links to the recipes that we used.
