If muffins come out with knobby shapes, what is the most likely reason?

Temperature controls how quickly the batter expands and how the crust forms. If muffins come out with knobby shapes, the most likely reason is baking at too high a temperature. When the oven is too hot, the exterior sets and browns too fast, trapping steam inside while the interior keeps expanding. That rapid, uneven expansion creates a top that is bumpy or knobby rather than a smooth dome. The other possibilities don’t produce that surface texture: batter that’s too cold tends to stay dense and slow to rise; overmixed batter develops a tougher, tunneled crumb rather than a lumpy top; too little leavening makes muffins flat and compact.
