Okay, another question. I'm starting to feel retarded, but I have so many questions, and I'm new- so bear with me!
Everytime I bake cupcakes, whether it be boxed or scratch, after they have cooled. . they seem to have formed a crust on top. Like, the tops are hardened and you can pick the hardened top off as a whole. I'm pretty sure thats not how they're supposed to be!

So, does anyone know whats causing this?
And how do I fix it?

Thanks!

i would maybe lower your baking temp or your baking time. i usually bake at 325 for about 16-17 min for box mix entended.

Try doing what Melvira told us. Preheat oven to 400 degrees and when you put the cuppies in back it down to 350 degrees. Sometimes I will even back it down to 325 degrees. They will also dome this way. HTH
