The Costco Fresh Fruit Topped Bar Cake with Vanilla Whipped Mousse is a Kirkland Signature bakery dessert featuring layers of light sponge cake filled and frosted with airy vanilla whipped mousse, finished with a colorful topping of fresh seasonal fruits.

Presented in a rectangular bar format, the cake is designed for easy slicing and sharing, yielding approximately 8 to 12 servings depending on portion size. The vanilla whipped mousse is light and mildly sweet, with a stabilized texture that holds its shape while remaining delightfully airy. The fresh fruit topping adds a bright, natural contrast to the cream layers, making this an ideal dessert for gatherings, celebrations, or everyday indulgence.

Like other Costco bar cakes, it comes packaged in a sturdy, resealable clear plastic container with a gold cardboard base, keeping the cake moist and easy to transport. For best quality, the cake is recommended to be served within one to two days of purchase due to the perishable nature of the whipped mousse and fresh fruit.
