Black Thunder Celebrates 30th Anniversary with Mister Donut’s New Crunchy Halloween Doughnuts
Among the myriad of chocolate options in Japan, one local favorite stands out for its affordability and quality: Black Thunder. This palm-sized chocolate bar, priced at just 35 yen (US$0.25), is a pocket-friendly delight packed with crunchy biscuit and cocoa cookie pieces. Its satisfying crunch and delightful blend of flavor and texture have made it a top seller in the Japanese chocolate market, proving that you don't need to spend a fortune to enjoy a premium chocolate experience.
Black Thunder, celebrating its 30th anniversary, has joined forces with Mister Donut for a one-of-a-kind Halloween collaboration. This unique partnership has given birth to a series of doughnuts in chocolate, white chocolate, and strawberry flavors. The chocolate variety, in particular, has been a hit among fans, offering a familiar taste with a crunchy twist, thanks to the inclusion of Black Thunder's signature cookie pieces. Priced at 216 yen for takeout and 220 yen for dine-in, these doughnuts are a must-try for anyone seeking a novel and delicious treat.
Fans Elevate Black Thunder Doughnuts with Crunchy ‘Chase the Thunder’ Hack for Extra Flavor
While many enjoy the doughnut as is, some fans claim it lacks the intense crunch of the original chocolate bar. To address this, they devised a clever hack called “Chase the Thunder,” which involves slicing open the doughnut and inserting two Black Thunder bars inside. This results in a jaw-testing, ultra-crunchy treat intensifying the chocolate flavor and texture, creating a decadent experience for true Black Thunder enthusiasts. However, strawberry doughnuts are recommended alternatives for those seeking a lighter option.
Black Thunder, known for its various flavors, including white and strawberry, has achieved cult status in Japan. Its popularity extends beyond chocolate with its merchandise and themed hotel rooms. Whether indulging in the new doughnuts or sticking to the original bar, Black Thunder fans have no shortage of ways to enjoy this iconic treat.
