Microwave Chocolate Mousse for One

Jump to Recipe

This small batch chocolate mousse recipe is so easy to make, you'll wonder how you ever lived without it! 😉 Featuring semi-sweet chocolate and heavy cream, it requires minimal prep time, no eggs, and no need to turn on the stove or oven.

A bowl of chocolate mousse topped with whipped cream and chocolate shavings, placed on a white napkin with a spoon and two strawberries beside it on a marble countertop.

A quick note: Anyday kindly sent me a set of their microwave cookware to try, and I've since joined their affiliate program. I used their 4-cup glass round deep dish to develop this recipe and loved it for this purpose, but any similarly sized microwave-safe dish will work. If you purchase through my Anyday links, I may earn a commission at no additional cost to you.

Okay, in case you're wondering, yes: you can use the microwave to make chocolate mousse. And it actually makes a seriously delicious (and extremely low effort) dessert.

The microwave will melt the chocolate and a little cream for the base, and then some whipped cream and chilling time do the rest. Super easy; I'll show you how to make it below.

Serving size: This recipe yields about one cup of mousse which I usually enjoy over one or two days for dessert. If you prefer just a few bites of something rich after dinner, you could easily enjoy it over 3-4 nights.

🌿 Ingredients

Top-down view of labeled ingredients for microwave chocolate mousse: a bowl of heavy cream, a bowl of sea salt and white sugar, a block of semi-sweet chocolate on parchment, and a spoonful of vanilla on a white countertop.

Look for heavy whipping cream rather than light cream for this recipe; that'll give you the fluffiest texture for the mousse.

You can find semi-sweet chocolate in the baking aisle, or use chocolate chips instead.

I tested this recipe with both granulated white sugar and powdered sugar and had excellent results with both. I thought that the granulated sugar might turn out too grainy, but I was actually pleasantly surprised that it did not.

See recipe card below for exact quantities.

⚙️ Equipment recommendation

4-cup microwave-safe bowl - I developed and tested this recipe using the Anyday 4-Cup Glass Round Deep Dish (affiliate link), which I love because you can melt, mix and store everything in the same bowl, but a similarly sized microwave-safe bowl will also work

Electric mixer - a hand mixer or stand mixer work equally well (affiliate links)

📝 Instructions

Chop the chocolate and place it in a microwave-safe bowl with a little cream.
A metal spoon rests in a frosted glass bowl containing melted chocolate and cream, viewed from above on a white marble countertop.
Warm and stir in 20-sec intervals until melted, then stir in a little extra cream.

Place the rest of the cream in a separate bowl and add the vanilla, sugar & salt.
A glass bowl of homemade whipped cream with a white spatula resting inside, on a white marble countertop.
Whip with an electric mixer just until soft peaks form (don't over whip.)
A metal spoon rests in a frosted glass bowl filled with chocolate mousse, sitting on a white marble countertop.
Reserve a little cream for topping, and fold the rest into the cooled chocolate.

Smooth out the surface and chill for at least one hour in the fridge.

✔️ Tips for success

  • Microwave in short intervals. Chocolate scorches easily, especially when you're working with such a small amount.
  • Let the chocolate cool slightly. Folding cold whipped cream directly into very hot chocolate can deflate the cream or make the mixture grainy.
  • Don't over whip the cream. Soft peaks are easier to fold into the chocolate and give you a lighter mousse.
  • Fold gently. You want to preserve as much of the airiness from the whipped cream as possible.
  • Give it time to chill. Refrigeration gives the mousse its classic thick texture (it's worth the wait) 🙂

🥧 Serving suggestions

Fresh raspberries or strawberries are fantastic with the rich chocolate of the mousse, or add a little whipped cream and shaved chocolate on top.

🍅 Use up the extras

Have heavy cream left over? Use it in this delicious whipped Greek yogurt recipe. Extra chocolate? Make these small batch chocolate chip cookies.

💭 FAQ

Can I make chocolate mousse entirely in the microwave?

You can use the microwave to melt the chocolate, but you don't want to microwave the finished mousse. Its airy texture comes from folding whipped cream into the melted and slightly cooled chocolate.

Why did my chocolate turn grainy?

It may have gotten too hot or come into contact with the cold whipped cream while it was still very warm. Heat the chocolate gradually and let it cool for several minutes before folding.

Can I eat it immediately?

Technically? Absolutely. For a true mousse-like consistency, though, give it at least an hour in the refrigerator.

Method
 

  1. Chop 2 ounces semi-sweet chocolate and place in a microwave safe bowl with 1 tablespoon of the cream. Microwave for 20 seconds, stir, then continue microwaving in 20-second intervals, stirring after each, just until the chocolate is melted.
  2. Stir 1 more tablespoon of cream into the melted chocolate and set aside to cool for about 5 minutes, until the chocolate is no longer hot but is still fluid.
  3. Meanwhile, add the remaining cream, 1 teaspoon granulated sugar, ¼ teaspoon vanilla extract, and a pinch sea salt to a separate mixing bowl. Beat with an electric mixer until soft peaks form (don't over whip the cream.)
  4. Fold about one-third of the whipped cream into the chocolate to lighten it. Gently fold in the remaining whipped cream until no obvious streaks remain, saving a small scoop to top your mousse with.
  5. Refrigerate for at least 1 hour, or until chilled and set.

Notes

Storage: Cover and refrigerate for up to 4 days. The mousse will become slightly firmer as it sits.
Substitutions: Milk chocolate works, but the mousse will be sweeter and a little softer. For the best balance, I like to use chocolate in the 60-70% cacao range.
Variations: Add a tiny pinch of espresso powder to intensify the chocolate flavor, a little orange zest for a chocolate-orange version, or top with berries, shaved chocolate, or a spoonful of whipped cream.
