This Honest Costco Tuxedo Cake Review is NOT sponsored and was written based on my honest opinion as a busy mom who likes a nice sweet treat every now and then!
Costco really does have an amazing variety of products – and desserts!
My husband and I love to describe it as a place that offers one (or maybe two in some cases) of everything but that thing is top notch.
The dessert we’re reviewing today is one of those things.
Costco tuxedo cake layers are creamy and delicious and the flavor does not disappoint.

Honest Costco Tuxedo Cake Review (We Hate that We Love It)
At first glance, just about everything this cake has to offer is exceptional – especially for a big box warehouse cake!
The beautiful design on top and alternating milk and white chocolate layers are stunning.
It looks great served individually and displayed on the counter for a birthday party.
Guests will love the flavor of alternating delicious layers of spongy cake and soft creamy mousse.
I can’t decide whether the top half or the bottom half of the cake is tastier!

The mixed chocolate square and white chocolate straw on top add a nice extra touch of texture to this dessert.
It really is in a league of its own for Costco desserts.
Is the tuxedo cake from Costco good?
Honestly, this cake is one of the most delicious treats we’ve picked up anywhere and it is without a doubt, the best cake we’ve ever purchased at Costco!
We loved trying it for small birthday party instead the usual slab cake.
This cake has so much more personality and our guests sincerely enjoyed it.
It went really well with our coffee in the evening and then as a treat the day after the party!

How much does Costco tuxedo cake cost?
The price of this tuxedo cake is $16.99.
Where to find it in the store?
You can find Kirkland Signature Chocolate Tuxedo Mousse Cake in the freezer in the bakery location. It’s usually near the birthday cake slabs, cheesecake, and occasionally cream cheese.
At our local warehouse, this is to the left of the muffins and freshly baked buns.

How many people will a Costco tuxedo cake feed?
Based on how we cut it, I’d estimate that you could get around 12 to 16 servings from this cake.
You may want to split pieces for younger kids vertically in two though (so they get to try all layers) since this cake is very rich and they likely won’t be able to finish it all – that was our experience.

It’s not great but this is about average for this style of cake made in this setting.
Now, let’s go over how it’s made.

Ingredients
This is where things go down hill for us – Costco’s tuxedo cake is FULL of yucky ingredients!
Here’s what its made with:
Cake (milk ingredients, sugar, water, chocolate, liquid whole egg, flour, cream cheese spread, white chocolate, margarine (modified palm and palm kernel oils, canola oil), cocoa, shortening preparation, (modified palm oil, propylene glycol, monostearate, mono and diglycerides, soy lecithin), icing sugar, canola oil, dry albumen, corn syrup, modified cornstarch, chocolaty coating, white chocolaty coating, colour, baking soda, baking powder, cooking and fancy molasses, salt, sodium phosphate, sodium alginate, soy lecithin, flavour, cellulose gum, xantham gum, carrageen, cellulose gel)
Pearls (coating [chocolate, white confectioner’s coating, glucose, sugar, acacia, modified cornstarch, coconut oil), beads (flour, sugar, wheat malt flour, wheat starch, baking soda, salt, cocoa butter, flavour)
Dark and white chocolates (sugar, modified milk ingredients, cocoa butter, cocoa mass, soy lecithin, flavour)
Whipped cream (cream, milk, sugar, cocoa, dextrose, modified manioc starch, carrageen, cellulose gum, sodium alginate, calcium sulfate, sodium phosphate, flavour and/or cellulose gel and/or mono and diglycerides and/or polysorbate 80)
This feels like it was made in a laboratory NOT a kitchen!
Contains: Milk, Soy, Egg, Wheat
May Contain: Sesame, Peanut, Tree Nuts, Sulfites, Triticale, Barley, Oats, Rye

Better Costco Dessert Options
We love the tiramisu cups from Dessert Italiano!
Since the European Food Safety Authority (EFSA) follows more strict regulations than we do here, European products tend to be higher quality and made with fewer questionable ingredients.
Check out our tiramisu dessert cups review and do a comparison between the novel of ingredients listed above to the one there.
How long is it good for?
Costco tuxedo cake is best up to five days after it was packaged.
Did you toss the plastic lid and can’t find the best before date?
No worries!
Check out your receipt or log in to your Costco account to see when you purchased your cake.
From there, count back five days – or do four if that makes you more comfortable!

Can you freeze Costco tuxedo cake?
Yes, and it freezes really well!
Since this cake is pretty rich you won’t need many slices at once though.
We recommend freezing them individually or as serving sizes according to how family people are in your family or whoever you expect to be sharing with.
We like these glass containers but Costco usually has something in a similar size at the warehouse.

You could also pre-freeze the cake for a short period of time to stiffen it up (one hour should be good) and then plastic wrap individual slices.
This works really well if you’re short on space or want to store them in small freezer pockets like those on the side doors or, in what’s referred to as a pizza compartment at the bottom front of your freezer.
Healthier Recipe
This Costco tuxedo copy cat recipe is unbelievable and uses REAL ingredients like:
- flour
- cocoa powder
- baking powder
- baking soda
- salt
- ground cinnamon
- ground espresso
- unsalted butter
- granulated sugar
- eggs
- vanilla extract
- canola oil (we suggest substituting this with avocado oil!)
- sour cream
- full-fat buttermilk
- strong coffee
- bittersweet chocolate
- cream of tartar
- heavy cream
It’ll take some time and effort but it’s worth making for a special occasion.
Costco Tuxedo Cake Review: Final Thoughts
This cake tastes phenomenal but the ingredients stink!
It has a wonderful rich and creamy flavor but we just can’t get over the amount of additives and unhealthy oils used in this cake.
Based on that alone, I don’t think we’ll be buying this cake again.
Instead, we’ll check out our local bakery and when the warehouse gets something new, we’ll give it a shot.
