Not letting the oven preheat

You could occasionally overlook preheating the oven. You can be so preoccupied with measuring and combining the ingredients that you forget to turn on the oven until the batter is in the pans. You shouldn't just put the pan into a cold oven, even if your batter is ready to go, and you should never do this in front of a baker. A critical step in baking is setting the oven to the proper temperature, and skipping this step can have a significant impact on the outcome.

You risk having raw batter on your hands if you forget to pre-heat your oven or don't let it heat up all the way. This can result in your cupcakes taking longer to bake or turning out underdone. Similar to how baking at the incorrect temperature - either too hot or too cool - can result in cupcakes that are sunken in the middle, have a dry or grainy texture, are dense, or are burnt - Livestrong makes this point. The final word? Preheating your oven should be the very first thing you do after carefully reading your recipe.
