Throughout the history of baking, brownies and blondies have been debated about which are better. While most people agree that they're both delicious in their own way, there's one element that differentiates them: chocolate! In order to make a true blonde (brownie), you must take out any traces of cocoa powder from your recipe--and this is why many recipes call for butterscotch as an added flavor instead. Brown butter and brown sugar are two ingredients in most recipes that help give a blondie its distinctive caramel-y taste!
