Hey everyone... So everytime I make cupcakes they sink in the center, doesnt matter if it is WASC or straight from box...(my scratch ones come out fine) Any idea what i can be doing wrong?

This happened to me, especially when I baked chocolate or red velvet cupcakes. I decided to bake them a minute or two longer and it came out okay...could be the temperature of your oven might be lower than you have set it for. Hope this helps.

What temp are you baking at? If your temp is too high, it will rise to fast and then fall. And your oven temp could be off too. Try baking at 335 and see if that helps.
