Vanilla Ice Cream That Isn’t Cold? A Specially Crafted Flavor
“Vanilla & Chocolate Chip Thunder” was developed with a focus on capturing the rich taste of vanilla ice cream.
The key to the flavor is the “fresh cream-flavored powder.” Using this helps express the rich milkiness and deep vanilla flavor unique to ice cream. With one bite, the fragrant aroma spreads through your mouth as if you were eating real vanilla ice cream.
Furthermore, vanilla-scented waffle crunch is mixed in. The composition is designed to evoke the essence of ice cream through both aroma and texture.
Four Ingredients Create the “Ultimate Crunchy Texture”
The biggest draw of Black Thunder is its uniquely hard texture, described in Japan as “zaku-zaku.” In this new version, four different ingredients are combined to achieve an even more complex and rhythmic crunch.
- Chocolate Chips: Generously added, providing sweetness with every bite.
- Waffle Crunch: Adds a light scent of vanilla.
- Biscuits: Create a substantial and strong crunch.
- Cocoa Cookies: Add a slightly bitter accent.
The mixing of these ingredients creates a texture that is never dull—it’s like an “orchestra of snacks” in your mouth.
Never Boring! A Bitter Chocolate Finish
While a vanilla and chocolate chip combination can often be overly sweet, this product is designed with the aftertaste in mind.
The bottom of the chocolate bar is coated with a purposefully bitter chocolate. This bitterness balances the overall sweetness, making the aftertaste surprisingly refreshing despite the snack being very filling. The exquisite balance of sweet and bitter will have you reaching for the next bite.
An Energetic and Pop Package Design
The fun nature of the product is evident right from the packaging.
The center features an energetic catchphrase: “Hop! Step!! Choco Chip!!!” The design is dynamic, looking as if the ice cream and chocolate bar are jumping right out at you.
The jagged patterns in the background visually represent the “zaku-zaku” crunchy texture that is the symbol of Black Thunder. The bright coloring, reminiscent of the arrival of spring, will make it easy to spot on store shelves.
