The new 'Featured Flavor' was announced Wednesday night on 'The Tonight Show Starring Jimmy Fallon.'

'Marshmallow Moon,' is part of Ben & Jerry's 'Special Stash,' a series of micro-batch ice cream that cannot be mass-produced or widely distributed.

According to Fallon, Ben & Jerry say it's the best flavor they've ever come up with. It's made up of vanilla ice cream, marshmallow, graham cracker swirls and fudge chunks.

You can only find 'Marshmallow Moon' at one of Ben & Jerry's Scoop Shops (only New Hampshire location is on Elm Street in Manchester). You can also order online through Ben & Jerry's website or have it delivered. Unfortunately, you won't find these micro-batch flavors at your local grocery store.
