Costco's Blueberry Trifle is a large, ready-to-serve layered dessert from the fresh bakery section. It features alternating layers of soft sponge or pound cake soaked in syrup, sweet blueberry compote or filling, rich vanilla custard or cream, and a generous topping of whipped cream, typically finished with fresh or glazed blueberries on top.

Designed to serve a crowd, this dessert is presented in a clear trifle bowl to showcase its decorative layers. It requires no preparation and can be served directly from the container, making it ideal for gatherings, potlucks, and celebrations. The dessert balances the tartness of blueberries with the sweetness of custard and the light texture of the cake layers.
