How many calories in a cup of Chocolate Mousse?

Chocolate mousse is a delicious, airy dessert that is made by folding chocolate into whipped cream or beaten egg whites. It’s an incredibly rich and decadent treat. But with all that cream and chocolate, it also packs quite a caloric punch. So how many calories are actually in a cup of chocolate mousse?

The Basics of Chocolate Mousse

Before delving into the calorie count, it helps to understand the basics of how chocolate mousse is made. There are three key ingredients:

  • Chocolate – This provides the chocolate flavor. Dark chocolate is often used since it has a more intense chocolate taste.
  • Cream – Heavy cream is whipped to soft peaks to give mousse its light, airy texture.
  • Eggs – Eggs are used as an emulsifier to stabilize the mousse. Egg yolks also contribute richness.

These three ingredients are combined through careful folding to create the mousse. Proportions vary between recipes, but a classic chocolate mousse contains about:

  • 6 oz bittersweet or semisweet chocolate
  • 2 cups heavy cream
  • 3 large eggs

The specific ingredients and ratios impact the final calorie count. More cream gives you a lighter mousse but packs in more calories. Dark chocolate has a stronger chocolate flavor but fewer calories than milk chocolate. And the number of eggs affects the richness. So the calories per cup depends on the recipe.

Calories in a Cup of Chocolate Mousse

Most recipes for chocolate mousse yield somewhere between 4-6 servings. Given this serving size, a single cup of chocolate mousse contains approximately:

367 calories

However, this number ranges from as low as 200 calories for a lighter mousse up to 550 calories for an especially rich and dense version. Here are some factors that influence the calorie count per cup:

  • Heavy Cream – More cream gives you a lighter mousse but adds more calories. Just 1 cup of heavy whipping cream has over 800 calories!
  • Chocolate – Dark chocolate has fewer calories than milk chocolate. And cocoa powder is less caloric than melted chocolate.
  • Eggs – Egg yolks add about 60 calories apiece, while whites have negligible calories.
  • Sweeteners – Sugar, honey, or syrups add calories. Artificial sweeteners do not.
  • Serving Size – The calories gets divided between the number of servings, so smaller servings mean more calories per serving.

So the calorie count can range quite a bit. But most standard chocolate mousse recipes end up in the 350-400 calorie per cup range. Whether you’re trying to watch your waistline or want to indulge guilt-free, the calorie count is an important consideration.

Calories from Each Ingredient

To get a more detailed view, we can break down the calories by primary ingredient:


  • 1 oz bittersweet chocolate (110 calories)
  • 1 oz semisweet chocolate chips (140 calories)
  • 1 oz unsweetened cocoa powder (20 calories)


  • 2 tbsp heavy cream (51 calories)
  • 1 cup heavy cream (788 calories)


  • 1 large egg yolk (60 calories)
  • 1 large egg white (17 calories)


  • 1 tbsp white sugar (45 calories)
  • 1 tbsp brown sugar (45 calories)
  • 1 tbsp honey (60 calories)

This gives you a good sense of where those calories are coming from. You can see that the cream and chocolate pack quite a punch! Reducing cream and opting for dark chocolate are two easy ways to lighten the calorie load.

Low-Calorie Chocolate Mousse

If limiting calories is your priority, there are some tweaks you can make to create a lighter chocolate mousse:

  • Use 1 cup cream instead of 2 cups
  • Substitute 2 egg whites for 2 whole eggs
  • Choose dark chocolate over milk chocolate
  • Use a sugar substitute like stevia instead of sugar
  • Fold in some whipped egg whites to make it fluffier

This would reduce the calories to around 200 per cup. While not as rich and creamy, it still offers plenty of chocolate flavor in a fraction of the calories.

High-Calorie Chocolate Mousse

What if you want an indulgent, ultra-rich chocolate mousse? You can pack in more calories by:

  • Using 2 cups heavy cream instead of 1 cup
  • Choosing milk or white chocolate which is higher in calories
  • Using 3-4 egg yolks instead of 2
  • Adding a sweeter like honey or maple syrup
  • Folding in whipped cream to make it denser
  • Topping with whipped cream and chocolate shavings

This could give you a chocolate mousse with around 500 calories per cup! While incredibly decadent, it may be wise to serve smaller portions.

Calories in Store-Bought and Restaurant Mousse

If you opt for chocolate mousse from a restaurant, bakery or pre-made from the grocery store, the calories can vary quite a bit. Here are some examples with calorie counts per serving:

Chocolate Mousse Source Calories
Trader Joe’s Chocolate Mousse 140
Whole Foods Chocolate Mousse 300
The Cheesecake Factory Chocolate Mousse 360
Paris Baguette Chocolate Mousse Cake 410
Godiva Chocolate Mousse 450

As you can see, the store-bought and restaurant versions also vary in their calorie content depending on the specific ingredients and recipe. But most contain 300-400 calories per serving.

Tips for Lightening Your Chocolate Mousse

If you want all the mouthwatering flavor but less of the guilt, here are some tips for reducing the calories in chocolate mousse:

Use a Lower-Fat Dairy Product

Heavy cream is the biggest calorie culprit. Try light cream or even non-dairy whipped topping to cut back. Just be aware this can impact the texture.

Choose Dark Chocolate

The darker the chocolate, the fewer calories it will contain. Stick to dark chocolate with a cacao percentage above 70%.

Replace Some Chocolate with Cocoa Powder

Cocoa powder offers great chocolate flavor for very minimal calories. Replace an ounce or two of chocolate with the same amount of cocoa.

Reduce Sugar

Cut back on the amount of sugar added, or use a lower-calorie sweetener like stevia, monk fruit or erythritol. Just a tablespoon less sugar makes a surprising difference.

Use Egg Whites Instead of Whole Eggs

Since egg yolks contain the majority of calories in eggs, using whites instead cuts almost half the calories per egg.

Go Easy on the Cream

You need the cream for texture, but too much really shoots up the calories. Use the least amount needed to make it smooth and creamy.

Make Individual Servings Instead of Large Desserts

It’s easy to overindulge when you have a whole pan. Portioning it out into individual ramekins helps control portions.

Top with Fresh Fruit Instead of Whipped Cream

Skip the usual whipped cream topping and go for lower-calorie options like berries or shaved dark chocolate.

Calorie Count of Popular Chocolate Mousse Brands

To give you an idea of how chocolate mousse calories stack up across brands, here is a look at some popular store-bought options (based on one serving):

Brand Calories
Jell-O Chocolate Mousse Temptations 100
Hershey’s Chocolate Mousse Kit 160
My/Mochi Ice Cream Chocolate Mousse 180
Trader Joe’s Chocolate Mousse 140
Sara Lee Chocolate Mousse Cake 340
Mars Chocolate Mousse Temptations 260
J&J Snack Foods Ultimate Chocolate Mousse 250

As you can see, calories range from 100-340 per serving depending on the specific product. Lighter, air-whipped mousses tend to be under 200 calories while richer, denser versions are over 300 calories.

High Protein Chocolate Mousse

One way to lighten chocolate mousse is to increase the protein content. Adding protein powder or Greek yogurt helps lower calories while increasing nutrition. Here is one high protein chocolate mousse recipe:


  • 1 cup light vanilla Greek yogurt
  • 1⁄4 cup chocolate protein powder
  • 1⁄4 cup cocoa powder
  • 1⁄4 cup honey or sweetener
  • 1 tsp vanilla extract
  • 1⁄8 tsp salt


  1. In a food processor, combine the yogurt, protein powder, cocoa powder, honey, vanilla and salt. Blend until smooth.
  2. Fold in 1 cup whipped cream, either store bought or freshly whipped.
  3. Divide mousse between 4 ramekins and chill for 2 hours.
  4. Top with berries before serving.

This contains only 143 calories and over 5g of protein per serving. It’s still rich and chocolatey but much lighter than traditional recipes.

Calorie Comparison With Other Desserts

How does chocolate mousse stack up calorically against other popular desserts? Here is a calorie comparison per serving (1 cup or serving):

Dessert Calories
Chocolate mousse 367
Cheesecake 370
Ice cream (chocolate) 277
Tiramisu 303
Brownies 213
Cookies (chocolate chip) 138
Cake (chocolate) 382

Chocolate mousse has a similar calorie count to many cakes and cheesecakes. It’s higher than lighter desserts like cookies or brownies. But for a silky, rich chocolate dessert, it’s on par with most options, calorically speaking.

Nutritional Profile of Chocolate Mousse

Looking beyond just calories, here is the full nutritional profile for 1 cup of chocolate mousse:

Nutrient Amount
Calories 367
Fat 30g
Saturated Fat 19g
Trans Fat 0.4g
Cholesterol 119mg
Sodium 88mg
Carbohydrates 23g
Fiber 2g
Sugar 20g
Protein 4g

As you can see, chocolate mousse is high in calories, fat (mostly saturated), and cholesterol. This comes from the heavy cream, eggs, and chocolate. It’s low in fiber, protein, and micronutrients. So while delicious, it’s not very nutritious. Moderating portions is advised.


Chocolate mousse can certainly be a delightful dessert. But with its high cream and chocolate content, it also packs quite a caloric punch. On average, a cup of chocolate mousse contains around 367 calories. However, this number can range from 200-550 calories depending on the specific recipe.

To lighter your mousse, use less cream, opt for dark chocolate, replace yolks with whites, and reduce any added sugars. Even with these tweaks, chocolate mousse remains a high fat, high calorie dessert. Alternatives like fresh fruit or sorbets are lower in calories. But when enjoyed in moderation, chocolate mousse can be part of a balanced diet.
