This Costco bakery coffeecake features a moist, tender lemon-flavored cake base topped with a generous layer of crumbly butter streusel. The bright citrus flavor of lemon is balanced by the rich, buttery sweetness of the streusel topping, creating a classic combination well-suited for breakfast, brunch, or a mid-day treat.

Baked fresh in Costco's in-warehouse bakery, the coffeecake delivers the satisfying texture contrast between a soft crumb interior and a lightly crisp streusel crust. Its generous size makes it ideal for sharing at gatherings, family breakfasts, or office settings. The butter streusel topping provides a caramelized, golden finish that complements the lemon notes throughout the cake.
