Ibaraki Milk Co., Ltd. is releasing a new collaboration package of its "Blissful Custard Pudding" featuring the beloved Moomin characters on Monday, April 6, 2026. To celebrate the launch, a prize campaign offering Moomin original goods will also be held.
Rich and Smooth "Blissful Custard Pudding"
The Blissful Custard Pudding is made with generous amounts of fresh cream and egg yolks, slowly steamed using specialized equipment — one of only a few of its kind in Japan — to bring out the full flavor of each ingredient. The result is a rich, full-bodied pudding with a smooth, melt-in-your-mouth texture.
The refined-sweetness pudding is paired with a slightly bitter caramel sauce, delivering a satisfying taste all the way to the last bite.
About the Moomin x Ibaraki Milk Co., Ltd. Collaboration Package
The packaging is designed around the theme of "happiness felt when eating the Blissful Custard Pudding," with a cheerful yellow color as its base. The design features scenes of Moomin Valley characters enjoying their own blissful moments — Moomin skipping along, Little My smiling, and Snufkin spending a peaceful moment.
Six Lid Film Designs Featuring Moomin Characters
Each pudding comes with one of six lid film designs featuring different Moomin characters:
- Moomin & Snorkmaiden
- Moominpappa & Moominmamma
- Snufkin
- Little My
- Mymble
- Stinky
The design included is random, adding an element of surprise with every purchase. Collecting three different designs also makes it possible to apply for the Moomin collaboration original spoon (Prize A in the campaign below).
