Trader Joe’s is a miracle of a grocery store if you love to indulge in “little treat” culture. Hard day at work? Bad night of sleep? Go ahead, get a little treat. Even Timothée Chalamet likes a little treat from Trader Joe’s.

In my opinion, the best treat at TJ’s is a seasonal one that’s only available for an extremely limited run. Every year, fans eagerly await for it to appear on Trader Joe’s shelves. It’s like the ultimate sign that spring is officially here—and that it’s going to be delicious.

I’m talking, of course, about the Trader Joe’s Carrot Mini Sheet Cake.

What is so special about Trader Joe’s carrot cake?

OK, first of all, it’s cute. It’s a tiny little sheet cake with adorably piped cream cheese dressing. It makes for a delectable afternoon treat—in fact, some enthusiasts even carry forks in their purses so they’re always prepared to dig in.

Aside from the aesthetics, fans go nuts about it because it contains no raisins. Raisins are a divisive addition to a lot of recipes, but the raisin-haters win here. Fans also like that it contains walnut meal as opposed to large chunks of nuts that can be difficult to chew. Basically, it’s all the best carrot cake flavors without anything to stop you from enjoying it very quickly—perhaps before anyone sees that you have it and asks for a bite.

Ultimately, the best part about the cake is the cream cheese icing on top. I cannot stress how imperative good icing is to carrot cake, and this one, well, takes the cake! It’s important that you inspect each of the mini sheet cakes and get one that has the frosting piped all the way to the edge—Reddit users have noted that edges and corners on some cakes are woefully under-frosted.

How long will the carrot cakes be available?

I don’t want to be dramatic, but you should stop reading this story and drive straight to Trader Joe’s if you want one. They’re only available for a limited time, and that fact, combined with their cult status, makes them disappear from shelves quickly.

The cakes hit stores this week, and their continued availability is totally dependent on the shopping habits of your fellow Trader Joe’s enthusiasts. Pack up your TJ’s cooler bag and go!
