Blondies or blonde brownies simply offer a different flavor profile, since they typically don't include chocolate.

In response to a fan who was looking for a way to create gooey blondies without the addition of chocolate, peanut butter, or butterscotch, Duff Goldman tweeted, "Maybe reconstitute some raisins." He went on to explain, "Soak the raisins in how [hot] water so the [they] plump up, then bake the blondies. They should get soft and deliciously mushy."
