The bars are now available in dairies across the motu, with boxes appearing in supermarkets later this month.
But one dairy let the cat out of the bag early, with Dunedin's Rob Roy Dairy sharing photos of the sweet treat on social media - and fans couldn't get enough.
One sweet-tooth exclaimed: "I have never needed something more!" while others labelled the innovation a "game-changer".
Kiwis overseas clamoured to find out if they were available overseas and discussed plans to return home just for a taste, while others schemed on how to protect their investment.
"Let's buy these and hide them from the kids," one hungry mum told her husband.
Sounds like a plan.
