Some Costco desserts are only around for a limited time.

The options for Costco desserts vary. Some products are available year around, like the Costco Tiramisu, whereas others only come during select seasons. You can always count on finding Costco sheet cakes, cookies, muffins, and pastries year around.
Apart from the regular favorites, Costco also offers a range of seasonal desserts that customers eagerly await each year. The Costco Pumpkin Pie, available during the fall, has a cult-like following. You may find more refreshing desserts like the Four Berry Pie or Lemon Meringue Cheesecake during the summer.
Best Costco Desserts You Should Buy:
1. “Mini” Lemon Cakes, 48 ounces ($8.99, or $1.50 per cake)

The newest flavor mini cake dessert to be offered at the Costco Bakery is the Lemon Cakes. Some may call these just giant cupcakes. These lemon ones are heavier, weighing in at 8 ounces each – that’s 6 ounces total more than the other flavors! They’re packed with lemony goodness: a lemon cake, lemon buttercream, a dollop of lemon curd, and some white chocolate curls on top. Oh, and they’re whipped up fresh right in the store.
2. Key Lime Pie, 68 ounces ($15.99, or $0.24 per ounce)

The Kirkland Signature Key Lime Pie is available again in summer of 2023. It’s priced at $15.99 for 68 ounces (or $0.24 per ounce). This pie, which weighs 4.25 pounds, could be a great option for bringing to potlucks, barbecues, and holiday meals. You can find this pie in the refrigerated section of Costco’s Bakery. It serves around 16 people, which means each slice costs approximately $1.
3. Strawberries and Cream Bar Cake, 46 ounces ($17.99, or $0.40 per ounce)

The Strawberries and Cream Bar Cake is a 46-ounce dessert priced at $17.99, which equals about $0.40 per ounce. This dessert consists of a white cake layered with strawberry filling and sweet whipped cream. It’s decorated with red-and-white striped white chocolate squares and white chocolate shavings, making it perfect for early summer gatherings.
4. Junior’s Celebration Layer Cake, 44 ounces ($16.99, or $0.39 per ounce)
Unlike other Costco desserts, Junior’s cakes aren’t baked at Costco but rather shipped in already done and ready to sell. Because it’s not baked in-house, you might find it closer to the ready-to-eat meals at your warehouse.
5. Costco Cheesecake, 72 ounces ($16.99, or $0.24 per ounce)

The cheesecake is priced at $16.99 for 72 ounces, which isn’t too bad for a big dessert. Year around you can find the original cheesecake flavor but seasonally, you will find Costco pumpkin cheesecake and occasionally a strawberry cheesecake.
The cheesecake is pre-marked for 18 slices, which would make each slice $0.94.
6. Lemon Meringue Cheesecake, 62 ounces ($19.99, or $0.32 per ounce)

Although the Lemon Meringue Cheesecake costs a bit more at $19.99 compared to the standard plain cheesecake price, the unique mix of ingredients and taste make it a superior option for dessert enthusiasts.
While this cheesecake is smaller than the original cheesecake, it still offers enough to comfortably serve between 16 and 20 people. That makes each slice as low as $1 a slice. I can get behind that!
7. Costco Peanut Butter Pie, 76 ounces ($19.99, or $0.26 per ounce)

Have you ever dreamed of a 4.5-pound, 12-inch giant Reese’s Peanut Butter Cup? Well if you have like me, then the Costco Peanut Butter Pie will be a dream come true. It comes with a buttery graham cracker crust, fluffy peanut butter filling, and a creamy chocolate mousse.
Typically a 12-inch pie can be cut into eight yummy slices, making each slice $1.67 for the peanut butter pie.
8. Four Berry Pie, 75 ounces ($18.99, or $0.25 per ounce)

For summer, Costco has brought a huge Four Berry Pie. The pie is a whopping 4 pounds 11 ounces and has wild blueberries, cranberries, strawberries, and raspberries. It can easily serve 10 people with healthy size slices, making it just $1.89 a slice! Throw some whipped cream on top and you have a slice of multi-berry goodness.
9. Lemon Blueberry Loaf, 33 ounces ($8.99, or $0.27 per ounce)

Costco’s Lemon Blueberry Loaf is a real treat. It’s packed with blueberries and comes with a butter streusel topping and lemon icing – all sitting on top of a tangy lemon batter. It’s a hefty loaf too, weighing in at 33 ounces. The price is pretty friendly at $8.99. Plus, if you can’t eat it all at once, no worries – it freezes really well.
10. Costco Tuxedo Chocolate Mousse Cake, 42 ounces ($16.99, or $0.40 per ounce)

The Tuxedo Chocolate Mousse Cake at Costco has chocolate cake layers, brownie pieces, and a mix of white and chocolate mousse. It’s finished with a layer of chocolate ganache and chocolate pieces.
For a price of $16.99, you receive 42 ounces of this dessert, making it a reasonably priced option for various occasions.
11. Costco Apple Pie, 75 ounces ($12.99, or $0.17 per ounce)

The Apple Pie from Costco is seriously tasty. It’s jam-packed with apples swimming in a sweet cinnamon slurry, all wrapped up in a flaky pie crust that’s just too good. The pie is a big one, coming in at 75 ounces. It’s pretty much a steal for the price — only $12.99. If you’re a pie lover or need to bring a big pie for a party, this one’s for you.
12. Costco Tres Leches Cake, 44 ounces ($14.99, or $0.34 per ounce)

The Caramel Tres Leches Bar at Costco is a must-try if you’re into sweet stuff. This 44-ounce bar of caramel deliciousness takes the classic tres leches cake to a whole new level. And for $14.99? That’s not too shabby. So, if you’re in the mood for something rich and indulgent, you might want to give this a shot.
13. Costco Tiramisu Cake, 38 ounces ($19.99, or $0.53 per ounce)

The Tiramisu Bar Cake from Costco is a delightful Italian dessert that combines convenience with deliciousness. It’s a sponge cake that’s been soaked in espresso, filled with rich mascarpone cheese, and dusted with cocoa powder.
This ample dessert is $19.99 for 38 ounces.
14. Costco “Mini” Cakes, 42 ounces ($9.99, or $1.67 per cake)

Costco offers a few different flavors of its “mini” cakes. Some may call these just giant cupcakes. Recently, we saw lemon, red velvet and raspberry cakes with buttercream icing. During the spring they even had mini carrot cakes with cream cheese icing. Most flavors are priced at $9.99, a package of six weighs in at 42 ounces which works out to almost half a pound each.
15. Costco Pumpkin Pie, 58 ounces ($5.99, or $0.10 per ounce)

The Costco Pumpkin Pie has its own cult following and for valid reasons too. It’s pretty awesome. You get this massive 58-ounce pie that’s all about that sweet, spicy pumpkin flavor, tucked into a crumbly crust. And it’s only $5.99, which is somewhat crazy. If pumpkin pie’s your thing, you should definitely check this one out when it’s in season.
16. Costco Carrot Cake

Speaking of mini cakes, Costco offers a few different varieties of carrot cakes. From the mini carrot cakes ($9.99) we found in the spring to a two and a half pound carrot cake bar cake($15.99), Costco sure knows how to bring the party with carrot cakes.
