Costco JM Desserts Chocolate Mousse Review

If you’re in the mood for an extremely rich and chocolaty dessert you’re in luck because Costco is currently carrying the JM Desserts Chocolate Mousse. These are individual chocolate mousse desserts from Belgium that look as fancy as restaurant-quality desserts! But, do they taste as good as restaurant quality?

Both Sean and I absolutely love chocolate so when we came across these new chocolate mousse desserts at Costco we knew we needed to pick them up to review and enjoy ourselves!

They look delicious!

Similar desserts from Costco are the Marie Morin Creme Brulee, Dessert Italiano Caramel Macchiato, Marie Morin Caramel Flan, delici Chocolate S’mores Souffle, Dessert Italiano Tiramisu, delici Belgian Chocolate Souffle and Dolce Mia Chocolate Dream Champagne Flutes.

You can find this in the refrigerated bakery section by all the Costco cakes. The item number is 1671843.


They’re very light, sweet and chocolaty! The biscuit base is quite firm with a little bit of crunch. Even with the somewhat solid base, it’s hard to remove the mousses from their trays to plate them without messing them up. They’re quite delicate.

Rich and chocolaty!

The biscuit base tastes fairly chocolaty, but not nearly as much as the rest of the dessert! These mousses are a chocolate lover’s dream. The mousse itself is rich, light and creamy. The ganache layer is quite thin, but rich. The mousse part tastes more like milk chocolate whereas the ganache tastes more like dark chocolate. The chocolate sprinkles on top don’t really stand out; they melt quickly in your mouth and blend in with everything else.

The mousse has a crisp chocolate biscuit base.


There are six individual-sized desserts in the package and the pack costs $13.49 Canadian which isn’t super cheap but also not overpriced in my opinion.

I think the price is pretty reasonable for what you get. Because the mousse is so rich I feel like two people could share one.

The mousse is a convenient, fancier-looking dessert!


Each mousse comes in its own small plastic tray. The best-before date is only about two and a half weeks from when I purchased the mousse and they need to be kept refrigerated.

Belgian chocolate makes the mousse extra delicious.

I think these are perfect for a dinner party! We bought them just to enjoy randomly when we’re craving something sweet and indulgent which is basically all the time for us!



One mousse is 270 calories, 19 grams of fat, 21 grams of carbohydrates, two grams of fibre, 19 grams of sugar, three grams of protein and 25 milligrams of sodium. When I think about how rich these taste 270 calories, 19 grams of fat and 19 grams of sugar doesn’t seem that high to me.

Nutrition facts.


These aren’t at all healthy and I don’t love the ingredients list. Specifically the palm oil carrageenan and the glucose and fructose syrup. The mousse contains wheat, barley, soy, milk and eggs and may contain nuts and sulphites.

Taste: 9/10

Cost: 7.5/10

Convenience: 10/10

Nutrition: 0/10


Must buy!

Overall these mousses taste as great as they look! They’re an elegant and rich dessert that any chocolate fan is sure to love.

  1. Looked this up because I recently bought them then had a total panic because on the box it says 3977 kcal per 100g and one dessert is 76g. OK for one small food item over 200kcal is high but is alot better that I first thought it was looking at the label
