when will portillos have the strawberry cake shake

Portillo’s appears to have offered a strawberry cake shake as part of its limited-time strawberry lemon cake shake lineup in past summer promotions, with one launch starting June 16 and another seasonal return page saying it’s available “for a limited time only” while supplies last.

What that means

• It’s not a permanent menu item.
• The most reliable pattern is a summer seasonal return.
• Portillo’s has also tied similar cake-shake flavors to limited-time dessert promotions, which suggests this one comes back in short windows rather than on a fixed year-round schedule.

Best practical answer

If you’re trying to catch it, watch for Portillo’s summer dessert announcements and expect it to show up around the start of summer again, not as an everyday item.

Recent context

Portillo’s has continued rotating limited-time cake shake flavors in 2026, which reinforces that these launches are seasonal and temporary rather than permanent. TL;DR: the strawberry cake shake is usually a limited-time summer item , and the safest expectation is that it returns seasonally rather than on a fixed date.
