Costco is famous for its tasty and high-quality cakes. Their Mini Lemon Cakes are a seasonal favorite, offering a soft lemon cake topped with sweet lemon icing and a bit of lemon curd. If you like lemon mixed with berries, the Lemon Blueberry Loaf combines the two in a delicious treat.
For quick bites, the Upper Crust Bakery Lemon Bites are small, tangy, and come in a resealable pack. If you want something richer, the Lemon Meringue Cheesecake gives you layers of creamy cheesecake, lemon curd, and fluffy meringue. These treats are not always available, so it’s good to check with your local Costco before buying.
