In the US, there are 3 main types of molasses: light, dark, and blackstrap, and they differ by their colors and sweetness level. Generally speaking, dark molasses is what's used for baked goods like bread, gingerbread, and Molasses Pie (aka Shoofly Pie). It has a rich flavor and lends its color to the finished products. Blackstrap is less sweet as it is bitter, not something you want in your baking!
