Oostvlaamse Vlaai is a local desert or snack that can kind of be compared to a bread pudding – you use a lot of (stale) cookies to make this. In this particular vlaai went a lot of gingerbread, very hard (and stale) speculaas and some macaroons. This gets seasoned with a lot of cinnamon and orange peel. You add a dark syrup and brown sugars to give the vlaai a dark brown color. This gets eaten with a cup of coffee, or people also like to spread it on bread.
