Mr. Ito Blueberry Tart Cookies

The Blueberry Tart has been part of Mr. Ito’s lineup since 2006 and marked its 20th anniversary in 2026 — a run that is unusual for a product this specific in its construction.

The format is worth understanding before the first bite.

The base is a custard-flavored tart shell — made with egg, sweetened condensed milk, skimmed milk powder, and cheese powder — baked in a flower shape until just set.

The blueberry jam is added afterward, not before baking.

This is what Ito Biscuits calls the “After Depot” method: jam applied to the already-baked shell rather than baked into it, which preserves the fresh, juicy character of the fruit rather than cooking it down further.

The jam itself is a blend of multiple blueberry varieties, each chosen to contribute something different — the balance between sweetness, tartness, and aroma — rather than relying on a single variety to do all the work.

After the jam is applied, each piece is left to rest for five days before shipping — long enough for the jam and the tart shell to fully integrate, the shell softening slightly as it absorbs moisture from the jam, the jam firming as it settles into the pastry.

The result is a texture that is neither crisp nor soggy but somewhere in between: moist, yielding, and more reminiscent of a proper tart from a pâtisserie than of a packaged biscuit.

Eight individually wrapped pieces. The version that has stayed on the shelf for twenty years without needing to change.
