Thicker and softer Sourdough Gingerbread Cookies are how we love our ultimate Christmas treats to be! Full of warming spices and treacly flavours from the brown sugar, gingerbread cookies are not only delicious but certainly a fun cookie to make! This is an overnight recipe though, so it will require some patience, but all good things are worth waiting for, right? Make the sourdough discard cookie dough in the evening, then chill it in the fridge overnight. Bake, ice and enjoy the next day!
