We picked up the new Costco Kirkland Signature Key Lime Cake for Father’s Day, the key lime cake has replaced the Kirkland Signature Tiramisu Cake. This is a fun new Costco cake released just in time for summer.

If key lime isn’t your thing and you want to see other Costco cake reviews I’ve done you might want to check out my reviews for the Costco Kirkland Signature Raspberry Lemonade Cake, Kirkland Signature Tuxedo Cake, Kirkland Signature Chocolate Celebration Cake, Kirkland Signature Chocolate Truffle Cake, Kirkland Signature Strawberry Shortcake and the Kirkland Signature Strawberry Cheesecake.

This can be found in the refrigerated bakery section and the item number is 1559792.

The Costco Kirkland Signature Key Lime Cake is not as good as the Costco Tiramisu cake but it’s still pretty tasty! It’s got a white sponge cake with subtle, sweet, key lime flavored icing both on top of the cake and between the layers of the cake. It has a whipped cream style vanilla icing around the edges of the cake and the sides are encrusted in cookie crumb.

The cookie crumb is delicious! In my opinion it tastes like coconut but there’s no coconut listed in the ingredients.

The cake is refreshing, sweet, moist and delicious if you like lime! It’s great for individuals who want a lighter cake or don’t love chocolate.

I do wish that they used real whipped cream instead of what’s actually on the cake because I think real whipped cream would cut the sweetness and I just really prefer real whipped cream over the fake stuff.

I paid $19.99 Canadian for the cake that easily serves 12.


The cake has a best before date of about five days from the date it was packaged. This is a perfect dessert for a summer birthday or barbecue. We had leftovers and I froze a piece to enjoy later in the weekend and it froze really well.

Definitely not healthy! The ingredients list is extremely long and full of unhealthy ingredients.

1/12th of the cake is 390 calories, 22 grams of fat, 230 mg of sodium, 44 grams of carbohydrates, one gram of fibre, 33 grams of sugar and four grams of protein. That’s a lot of sugar, carbs and fat but that’s to be expected when it comes to cake.


Taste: 7.5/10

Cost: 8/10

Convenience: 10/10

Give it a try!

Not my favorite Costco cake but I did still enjoy it! I’m more a chocolate cake kind of girl!

  1. Our daughter bought one and shared it with us. LOVED IT!!! If calorie counting is important to anyone, this probably isn.t a good choice.

  2. We were at Costco today looking for key lime cake. We were told this cake was discontinued. Too bad… We really miss that delicious, light and refreshing taste. It was our birthday celebrations, weekend gather party No. 1 favorite cake.

  3. Yummy!!! Delicious lime cake. Light, tasty and refreshing. Our favorite No. 1 Costco cake for birthday celebration, weekend gathering party or once in a while treat…
    Just love it!!!

  4. I am inquiring about the ingredients in this cake – what is the source of mono and diglycerides?
    Cellulose gel and polyglycerol esters of fatty acids
    Are these derived from
    Plant source or animal source ?

  5. Thanks for reviewing! I do like something other than chocolate cake at times, but especially in the summer, something light and fruity is right up my alley. My birthday is coming up in a couple weeks and I think this one will be great as I’m not a fan of traditional birthday cake either.
