Costco’s New Mocha Crunch Bar Cake Is a Must for Coffee Fans—and It’s Under $20

Coffee and dessert enthusiasts have a new reason to visit Costco this fall: Costco recently introduced its Mocha Crunch Bar Cake, and it is quickly generating buzz online.

For just $19, the coffee-infused dessert promises to satisfy cravings without breaking the bank, making it an ideal choice for both casual indulgence and seasonal gatherings.

A Deliciously Layered Dessert

The Mocha Crunch Bar Cake combines several layers of flavor and texture. It begins with a rich chocolate cake, followed by a mocha crunch layer that adds a delicate, nutty flavor. Topped with silky mocha mousse and a light cappuccino cream, the cake is finished with a chocolate drizzle and white chocolate curls, creating a visually striking presentation. The result is a dessert that tastes indulgent and looks impressive on any table.

Beyond its flavor, the Mocha Crunch Bar Cake is visually stunning. Its layered look and cappuccino topping make it a show-stopping centerpiece for dessert tables or Instagram photos. Affordable at under $20, it’s a practical yet impressive choice for parties, family dinners, or just indulging at home.

How It Compares to the Tuxedo Cake

Many shoppers have already compared it to Costco’s beloved Tuxedo Cake, a long-time fan favorite. While the Tuxedo Cake features a classic chocolate-and-vanilla combination, the Mocha Crunch Bar Cake leans into the rich, roasted flavors of coffee, offering a more mature twist.

Reddit users have described it “like their (Costco's) Tuxedo Cake but with mocha frosting,” making it a must-try for coffee enthusiasts.

Tips for Serving and Enjoying

To get the most out of your Mocha Crunch Bar Cake, presentation and pairing matter. Serve it slightly chilled for optimal texture; this keeps the mocha mousse and cappuccino cream layers firm while preserving their creamy richness. Pair slices with a hot cup of coffee or a cappuccino to enhance the coffee flavors, or enjoy them alongside vanilla ice cream for a contrast of temperatures and textures.

For gatherings, consider cutting the bar cake into smaller portions so everyone can sample it without committing to a large slice. Leftovers can be stored in the freezer for up to a month, making it a convenient dessert for future indulgence.

A Seasonal Must-Have

The cake is generously sized, easily feeding eight to twelve people, making it perfect for fall gatherings or a special family treat. Many Costco cakes come pre-frozen, and this bar cake is no exception. Shoppers recommend slicing it before freezing so individual portions are ready to grab whenever a craving hits.

Like many of Costco’s limited-time offerings, the Mocha Crunch Bar Cake may only be available for a short time. Early reviews indicate that fans are enjoying the blend of rich chocolate and subtle coffee flavors. One Reddit commenter mentioned that the crunch layer isn’t for everyone, but the balance of mocha and chocolate creates a satisfying, not-too-sweet dessert.
