The Kirkland Signature Strawberry Whip Iced Filled White Cake is a rectangular bar cake from Costco's in-house bakery. It is built from alternating layers of tender white shortcake, a strawberry filling made from real strawberry puree and juice concentrate, and stabilized whipped cream—with cream listed as the primary ingredient. The exposed sides of the bar display the striking red and white strata of the layers, while the top is decorated with white chocolate curls and pink-and-white striped chocolate squares. Color in the decorations comes from natural beetroot extract; no artificial colors are used.

The bar weighs approximately 2 lbs 14 oz and serves 8 to 12 people depending on slice thickness. It is packaged in a clear, resealable rectangular plastic box with a gold cardboard base, making it easy to transport and store in the refrigerator. Because the whipped cream is stabilized rather than traditional, the cake holds its shape well but is best consumed within one to two days of purchase. It can be sliced and frozen for longer-term storage.
