What kind of pie orcake on the truvia commercial when girl eats it all and only berries are left plate?

Unfortunately, I don't have access to real-time information, including specific details from commercials. This means I can't tell you what kind of pie or cake was featured in the Truvia commercial you're referring to.

To find out, you might try:

* Checking the Truvia website or social media: They might have information about the commercial or even recipes for the dessert featured.

* Searching online: You could try a search like "Truvia commercial pie" or "Truvia commercial cake" and see if any results come up.

* Contacting Truvia directly: You could reach out to them through their website or social media channels and ask about the commercial.

I hope this helps!
