Not sure I like pairing Moscato. It leans very heavily into stone fruit rather than into the berries and cream in Oops All Berries. I like Prosecco better. It can be a bit nutty.
For me, personally, ideally I want something with some lees aging. That often gets into rich, bready flavors. So a demi sec Champagne or Cremant would work. A rose Cremant d’Alsace maybe even?
Edit: Also Sherry.

Chardonnay isn’t usually vinified sweet enough, sadly, to stand up to Corn Pops and Honeycomb. There probably is one, somewhere, but it’s a reach. You’d really want Sauternes or Tokaji Aszu. They’re produced from grapes infected with a rot that gives them honey flavor notes.
Champagne and Port I like. Rice Crispies I’m curious about. Why and from where?
