Blondies Food historians generally agree that recipes named "brownies" and chocolate brownies [as we know them today] were first introduced in the beginning of the 20th century. This coincides with the mass production [availability & affordability] of chocolate and cocoa. Here are our notes on the history of [chocolate] brownies. According to old cookbooks, blonde brownies (also known as "Blondies") predated chocolate brownies, though under different names. The primary ingredients of blondies (brown sugar/molasses and butter) compose butterscotch, a candy that was popular in America in the mid-19th century. Some 19th century American cookbooks contain recipes that combined traditional butterscotch ingredients with flour and a leavening agent (baking powder or soda). Presumably, these recipes would have produced something similar to the blonde brownies we enjoy today. The Tortilla Guy
