This recipe for chocolate mousse made in a blender comes via the pastry chef Natasha Pickowicz, who got it from a cook named Monica Stolbach, who in turn got it from her mother-in-law, who got it from a Junior League cookbook published in the 1980s. Straightforward, adaptable and extremely satisfying, it’s one of those recipes that you want to pass along to as many people as you can. Instead of separating the egg yolks and whites, this technique simply involves pouring hot sugar syrup into a blender with chocolate and whole eggs, then folding that mixture into softly whipped cream. The resulting texture is so creamy and rich, it doesn’t need anything at all, though you can top it with extra whipped cream, if you like. —Tejal Rao

Preparation

  1. Step 1

    In a large bowl, or in a stand mixer on medium speed, whip the heavy cream to glossy, medium peaks, about 5 minutes. Set aside in the fridge. In a small saucepan over gentle heat, melt the sugar with ¼ cup water until dissolved. As soon as the syrup begins to boil, turn off the heat.

  2. Step 2

    Add chocolate and eggs to a blender. Blend on medium-high speed while slowly pouring in the hot sugar syrup, which will melt the chocolate and cook the eggs. Keep the machine running until the mixture is extremely smooth, then stream in the espresso, rum, vanilla and salt. Keep blending until the mixture has cooled to room temperature, about 1 minute, pausing to scrape the sides as needed.

  3. Step 3

    Fold 1 cup of the chocolate mixture into the chilled whipped cream until smooth, then add the rest of the chocolate mixture to the cream mixture and fold until there are no streaks. Pour into individual bowls, ramekins or glasses, and set in the fridge until firm, at least 2 hours or up to 24 hours. Serve chilled.

Can a food processor be used in place of a blender?

1/2 c Milk 1 c heavy cream 2 t Butter 1/2 t Instant Coffee 2 Eggs 5 oz semisweet chocolate chips 2 t Cognac or vanilla 1 t Powdered Sugar 1 oz unsweetened chocolate Heat 1/2 cup milk & 1/2 cup cream until it bubbles (Do not boil or scorch). Remove from heat. In blender mix butter, eggs, coffee, chocolate chips, liquor until creamy.On low speed, drizzle in the very hot milk. Blend until smooth, 1 minute.Divide liquid in 4 serving dishes chill 4 hr Beat remaining 1/2 cup heavy cream powder sug

I eliminated the blender and all of the ingredients except the rum, which I tripled. To be honest, it tasted nothing like chocolate mousse, but somehow it didn't really matter.

If I want to avoid the alcohol, I don't think I can just leave it out. What can I use to replace the 1/4 cup of liquid in the recipe?

This is insanely good!! Followed the recipe as written and just knocks your socks off with the richness, texture, and flavor intensity. Used dark Jamaican rum. Directions were spot on. Used Artisan Kettle organic extra dark chocolate, 72% cacao. Already in tiny chunks. I honestly can't understand why people use NYT Cooking site to promote their own recipes. If that's what you want to do then go to Allrecipes or see if Sam Sifton will hire you. Thanks very much Ms Rao

Followed the recipe exactly. Turned out perfectly. As much as I appreciate the comments with alternate versions, I like to hear that it works as instructed too.

I make foolproof mousse much more easily: Mix 1/4 cup sugar with 2 Tbs water, microwave for 1 minute. Add a bag of dark chocolate chips (10 oz.) and 1/2 stick of butter. Microwave for two more minutes, take it out and stir until all the chocolate is melted. Separate three eggs. Add 1/2 tsp vanilla and the three egg yolks to the chocolate and stir; add a little Nescafe if wanted. Whip the 3 egg whites and fold in. Refrigerate, in ramekins if you like, until firm. Serves about 5.

Oh, YES! Made what I believe was this exact recipe, decades ago (from a newspaper clipping), and have been hoping to uncover the old clipping or an alternate source. Incredibly easy; incredibly good. Earned raves at dinner parties as a young wife when I didn't know much about cooking. Thank you, Tejal Rao! In case of desperation, can use stick blender/egg beater as alternative to blender; can replace coffee with water or extra rum; can replace rum with water + extra vanilla (for flavor).

All the recipe says is dark chocolate. What percentage is it? This is extremeny important because it can change the amount of sugar you add to the mouse depending on how sweet or bitter your final mousse will be.

This is basically the same recipe that came with my Cuisinart food processor in 1980. In that recipe, you process two eggs with 1 cup of chocolate chips for about 30 seconds, the with the food processor running, you pour in the boiling syrup made from the sugar and water. It melts the chocolate and heats the eggs enough to not be a problem. I know, I’ve been making and eating this for 40 years and I’m immuno-compromised.

Easiest of all, and delicious, this is from 30 years ago. 3/4 cup milk 6 oz semi-sweet chocolate chips 1 egg 1/8 tsp salt 1 tsp vanilla 2 tbsp sugar Heat milk until just short of boiling. Blend chocolate chips, beaten egg, salt, vanilla and sugar in blender until smooth. Add hot milk, beat 2 minutes at high speed. Break bubbles with wooden spoon and pour into pot de creme pots. Chill for several hours or overnight. Makes 6 small pots.

I saw this and made it immediately as I had all ingredients on hand. The end result looks nothing like the photo and really lacks that airy mousse texture. While the taste is fine, this really turned into more of a ganache with a bit of a greasy/rich mouthfeel.

Curious -- where does the fiber come from?

For the blenderless among us, will a food processor work and if so which blade?

Would Vitamix work?

Wanted to like the recipe- smells delicious. Sadly, it broke our blender before completed. Will stick with a normal mousse recipe next time.

Used 12.5 oz ghirardelli 72% dark choc chips (low sugar) and brandy. Put eggs in blender first with chocolate on top for best texture. Beat the cream well. Made 9 7-oz ramekens. Result: dark chocolate mocha brandy mouse with firm but airy texture. Would have preferred chocolate mousse with hints of coffee and brandy. Feedback from 12 people: 1 perfect, 1 too strong, rest 'yum but better with less coffee/brandy.' All added extra whip cream and fruit to cut intensity.

The reason this gets 4 instead of 5 stars: instructions are vague regarding type of chocolate & alcohol with no advice on how substitutions/omissions could affect outcomes. Results will vary widely depending on type of chocolate/alcohol and on how long you beat the cream. Even putting chocolate below the eggs in the blender affected how things cooked/melted and therefore the texture. Easy to make, but also easy to make badly if not careful. A few edits could increase number of yummy results.

I made this for Mother's Day dinner tonight and everyone loved it! We don't drink alcohol or coffee so I put in about 1/2 c fresh squeezed orange juice strained through a sieve. It wasn't strong enough to give a pronounced orange flavor but it gave a more complex flavor along with the vanilla For those worried about the eggs cooking, sugar water boils at a higher temperature (around 280*) so it is plenty hot enough if you use room temperature eggs and chocolate.

Not sure. But you could make it as written and eat two helpings

Can you half this and not suffer bad consequences?

Made this for Valentine's Day, followed the recipe exactly, and it turned out divine. If you love chocolate, and you still didn't try this recipe, what are you waiting for:) (used cheap brandy from Trader Joe)

How much water to make sugar syrup? Is it one to one? Recipe doesn’t say

It says in the instructions- 1/4 c.

Can I halve this recipe?

Can these mousse cups be frozen?

This was delicious and so easy! I used dark chocolate chips because that's all I had. I used rum, but next time I might try Chambord.

If I use 1/4 cup Kahlua (coffee flavored rum) in place of dark rum, should I leave out the 1/4 cup espresso? If so, what do I add to replace 1/4 cup liquid?

Made it as the recipe directed and turned out great! I agree it is not as silky as typical mousse and a bit more rich and thick. It also could use a bit less rum although my husband disagrees and thinks it’s perfect. I would recommend the whipped cream topping to help cut the richness and small servings :) enjoy!

I had been making Alton Brown's mousse for the longest time but it was always such a pain to make. I found this and I'm never looking back. So easy. I pulled everything together while the heavy cream whipped to medium peaks. The piping hot syrup was just enough to melt the chocolate and egg mixture to very smooth. My vitamix was more than up to this task. 10/10 will make again for Christmas family get together.

Note to self, use bittersweet chocolate. It seized horribly when I used 100%. Also, it's okay to put the eggs and chocolate in the blender together before starting the sugar syrup.
