I hate when I run out of batter and can't fill up my muffin pan. If you only have half of the holes filled, there's a chance that your muffin pan will warp. To avoid this, you can fill the empty cups up with water, and Voila! No warpage.
Is warpage a word? Probably not. But my tip is still valid and that's all that matters!
