Sheet cake usually screams party-sized indulgence and plenty to go around, but Trader Joe’s Yellow Mini Sheet Cake flips the script as a bite-sized version that delivers all the fun in just a few bites.

Trader Joe’s Yellow Mini Sheet Cake comes together with ingredients like a buttermilk cake base, vanilla extract, rice flour, potato starch, cornstarch and tapioca starch, and it’s all finished off with a rich chocolate buttercream, also made with vanilla. As such, Trader Joe’s moist, scaled-down sheet cake satisfies the sought-after pairing of yellow cake and chocolate frosting.

Although Trader Joe’s Mini Sheet Cakes have been savored since their launch in 2018, this new launch is relevant in 2025 with the rise of portion-controlled treats and the demand for inclusive, gluten-free options.
