It's time to talk cake again! I've reviewed the Costco Kirkland Signature Tiramisu Cake and the Strawberry Shortcake. Today I'm reviewing Costco's Tuxedo Cake. At this risk of spoiling the rest of this review, I think this is the best cake that Costco sells!


First off, this cake does not taste like it came from a grocery store! I eat a lot of desserts, so I feel like I know my cake well. Costco's Tuxedo Cake is nothing like those cakes you buy at your local grocery store (you know, the ones that are dry and have artificial-tasting icing). This cake is rich, chocolatey and you can definitely taste the high-quality ingredients it uses. You only need a small slice to sink into sweet, chocolatey heaven. The cake consists of a few different layers. The bottom layer is a dense, bold-flavored chocolate cake. On top of that is a rich, creamy chocolate mousse with brownie pieces in it. Next up is a vanilla/white chocolate cream mousse. Sandwiched above that is another layer of chocolate cake. Topping it all off is a thick, smooth dark chocolate ganache. The top of the cake is decorated with cocoa nibs and chocolate sticks, which makes it very visually appealing on top of being extremely delicious. I honestly love this cake so much that I’d rather have it than a cake from one of the top-notch bakeries we have in my city! Overall, this cake all together is sweet, rich and quite decadent, so some people might find that it’s too much. Personally, I can’t get enough of it and would happily have it as my birthday cake. It’s not too rich for me and I’m crazy about the smooth, creamy mousse!


At $16.99 Canadian, the price for the Tuxedo Cake is the same as for the Tiramisu Cake, which in my opinion is very reasonable. I could easily see this cake serving 10 - 12 people, so that's pretty inexpensive on a per-serving basis. I'll let you in on a secret. We've purchased a chocolate cake for $48 Canadian from a fancy local bakery - it's one of their signature items. It's really good, but not $30 better than this cake! Not even close! The Costco Tuxedo Cake tastes just as good as the fancy bakery cake to me.


The Tuxedo Cake is as convenient as a product can be! It comes packaged in a rectangular plastic container that you can easily reseal after opening. The cake slices super easily and freezes wonderfully.


I don’t know the nutrition information for this cake and I don’t want to know! Can we please just pretend that it's healthy?!

I can't say enough good things about this cake! You have to try it. If you hate it, just send your leftovers to me and I’ll gladly finish it!
