Yes, they should! Although it is a bit of a personal choice. Some people prefer their blondies drier, and more 'cakey' instead. If you like your blondies to be moist and characteristically gooey in the middle, be sure to take them out of the oven when the edges are starting to brown, but there is still a slight wobble in the middle of the bake. For less gooey blondies, increase the baking times by few minutes.
