I might suggest a toilet paper storage cylinder like this: https://smile.amazon.com/dp/B00J1ZM2C4/ref=cm_sw_r_apan_i_ZD806EWDHJ635TTR3CHB

I was initially looking for one that might open at the front with a sort of shelves for the different kinds of rice cakes, but thought I'd reply first and come back with an edit if I find something like what I originally imagined.

Edit: Or maybe a toilet paper storage tower like this: https://smile.amazon.com/dp/B07MH35NFJ/ref=cm_sw_r_apan_i_A22AP62596EWZFZ1QD5A Since it has a door, it might be easier to access the different flavors. And still looking!

Edit 2:. Another option for ease of access would be something designed for rolled towels that hangs on the wall, like this: https://smile.amazon.com/dp/B09PDFFNYL/ref=cm_sw_r_apan_i_8ZQFCCDTNRHY66WHH223 It won't keep them out-of-sight, but would keep them off the counter and easily accessible for nibbling.
