Yes, I wasn't sure either but she clarified in the comment section...
What I did was heat my oven up to 350, put my cupcakes in, then lowered it to 325. So as soon as I put my cupcakes in, the temperature started to lower. I don't know if it's right, but it worked for me!
Note she also said she filled the liners to 3/4 full vs. 2/3.
I'm excited to think I might not have flat cupcakes next time. It's always bugged me.
