Help me remember this cereal

[Shatandfattered]

I'm currently eating a pack of bobby's BBQ potato snax crisps and I'm convinced I remember a cereal with the same shape and structure, almost like a circle, 3d shreddie type thing? Please help 🙏

Was the best. So light and crunchy!

Yummy, but they're square shaped, hollow "pillows" .

I jsed to love these and haven't seen the fkr years. But Google just told me they're not called Oat Crisp so I'm going to look for some next time I shop!
