Just keep working at it. Keep in mind she's still a baby ... a baby who's all excited about her food, and she wants it, and she wants it NOW!
It's going to take her learning self-control to be calm, so take any tiny moment you can get. Do you clicker train? If not, this may a good time to start. And if so, maybe grab the clicker and use that too (yeah, I know, and your extra set of hands
) - and not only have the bowl ready, but the instant she's calm for even a second, click and put the bowl down. A moment of calm will be when she gets her food. Then after a few days of a moment, try for two moments. Don't go for a minute, start small and work up - we're talking a second. And you be sure to pack all your patience before her meal time, don't be frustrated with her big show. Just take a deep breath and ignore it. Maybe have a few kibbles or treats on the counter handy (don't know what you feed) and IF she by chance is quiet for
even a second, toss something to her immediately so she gets the idea "hey, I get something if I'm quiet!". She'll start figuring it out, cuz dogs do what works for them. It'll happen, she'll get it.
