How do you make ben and jerrys wavy gravy ice cream?

Unfortunately, Ben & Jerry's has never made a "Wavy Gravy" ice cream flavor. It's possible you're thinking of a different flavor or it's a fan-made creation.

Ben & Jerry's is known for their wacky and creative flavors, so if you're looking for something similar to what you described, I can suggest some other flavors you might enjoy:

* Chocolate Fudge Brownie: This classic flavor features a rich chocolate ice cream with chunks of brownie.

* New York Super Fudge Chunk: A decadent blend of chocolate ice cream with gobs of fudge, walnuts, and chocolate cookies.

* Coffee Coffee BuzzBuzzBuzz!: This flavor is perfect for coffee lovers, combining coffee ice cream with espresso bean fudge chunks.

If you have a specific flavor in mind, please let me know and I can see if I can find more information about it.
