Costco Kirkland Signature Sour Cream Butter Pound Cake Review

The name “pound cake” originates from a recipe that called for a pound of each of its four main ingredients: butter, sugar, eggs, and flour. Costco is offering its own rendition of this timeless treat in the form of the Kirkland Signature Sour Cream Butter Pound Cake, incorporating sour cream into the mix. Sour cream tends to work well in cakes because it enhances the moisture level without diluting the batter, resulting in a moist yet dense texture. Has Costco done enough with these simple ingredients to make this Pound Cake worth buying, or it is too plain and boring?

Other cakes from the Costco bakery are the Kirkland Signature Raspberry Cheesecake, Kirkland Signature Tuxedo Cake, Kirkland Signature Tiramisu Cake, Kirkland Signature Carrot Cheesecake, Kirkland Signature Pistachio Cake, Kirkland Signature Raspberry Lemonade Cake and the Kirkland Signature Lemon Poppy Seed Loaf.

Location in Store

This is located in the non-refrigerated bakery section at Costco. The item number is 1719752 and I bought it in Kalispell, Montana.

The cake is pretty large and dense!


The cake itself is quite plain and a medium density; somewhat moist and somewhat light. It’s spongy with a fine crumb and almost melts in your mouth. I don’t know if you can call a cake smooth, but that’s what crossed my mind as I was eating the cake. It doesn’t have much texture.

Although it’s dense it’s fluffy with a fine crumb.

The icing on top mostly adds sweetness – it’s pretty sweet! The entire cake is fairly moist despite the layer of icing being quite thin. The sour cream flavor isn’t particularly noticeable, but it’s there if you pay attention and look for it. You’ll notice a slight hint of tang from the sour cream.

Ready to slice!

I’m not really sure what else to say about this Pound Cake or how to rate it. It’s good, but very plain. I think it might be better if it were served with a berry compote or something to add a bit of flavor.


The cake costs $7.99 USD which isn’t bad for such a heavy, huge cake. It’s also pretty plain and not very fancy so I don’t think I’d pay more than $7.99.

The glaze on top is light.


The cake has a best-before date that’s four days from the day it was purchased on. The cake doesn’t need to be kept refrigerated despite containing sour cream but if you’re not going to be eating it right away I’d probably slice it up and freeze it to maintain freshness.

I think this cake is pretty boring on its own and it tastes like its lacking something so I’d recommend having it with a berry compote, strawberries and whipped cream, ice cream or grilled peaches.



There are 16 servings in the cake and one 120-gram serving contains 370 calories, 17 grams of fat, 210 milligrams of sodium, 51 grams of carbohydrates, one gram of fiber, 44 grams of sugar and six grams of protein. That’s a lot of sugar and carbs, which isn’t surprising.


Sugar is the first ingredient followed by flour, eggs, butter and sour cream which is what pound cake should have! If you make your own pound cake at home you probably wouldn’t be adding a bunch of ingredients I don’t love seeing like soybean oil, palm oil, artificial flavors and soy flour.

This is why baking at home is something I always prefer over store-bought baked goods. I like simple, whole ingredients and I don’t think it’s necessary to have all these other ones added.

The cake contains wheat, egg, milk and soy and may contain peanuts, tree nuts and sesame.

Taste: 7/10 (It’s good! Just a bit boring.)

Cost: 8/10

Convenience: 10/10

Nutrition: 0/10


Give it a try!

I personally wouldn’t buy this again because I find it a bit lackluster but it’s not bad or anything like that! The cake is moist and sweet and tasty, just a bit plain.

  1. I’m a confused by your review. The cake is $8 USD? Are you sure you bought it at a Canadian Costco or did you get it from the States? I think the Costco apple pie is a better deal for $10 CAD, it’s so much bigger and actually tastes good, weighing about 1.350 kg.

  2. I guess this is what you get when you make “food” on a production line and schedule. Not what I would call as resounding “gotta buy it”.

    I would “Give it a try, though.” Go great with your morning coffee, I’m sure, despite the sub-standard taste/texture.

    Make it and bake it … yourself! You control what goes into it. Flavor, nutrition, quality of ingredients.

    Looks like someone made a trip to Kalispell. Probably get it in Spokane and Coeur-de-Alene which is closer for me. Haven’t seen it in my store. USA only perhaps … they do that.

  3. I found the cake to be dry and very bland. Ended up throwing it away. Went in looking for the lemon blueberry (moist and delicious) to be told by a bakery employee it had been replaced by the pound cake.

    • You could have made it into a strawberry shortcake or added some custard cream the recipes are endless, you didn’t have to throw it away there are so many children that are starving out there

  4. 44g of sugar per serving? Holy moly that’s 11 teaspoons in one slice!!! It better taste amazing for that much sugar imho. Nope. Not happening lol. Thanks for your review! 😳

    • Krikey … no kidding,that’s 9g more than a “full-on” can of Coke. Yes, but every so often, spread between two people (presumably) and over a 4 day period … you can probably handle it. I expect your pancreas will forgive you.
