This simple recipe for white chocolate mousse is made without eggs or gelatin, and can be served alone, with berries, or even as the perfect cake filling!
Most recipes for chocolate mousse call for making an egg-based chocolate pudding, and folding that into whipped heavy cream. They're delicious and I love them. But they're also a bit finicky to get exactly right.
You can make white chocolate mousse by just melting straight-up white chocolate and folding it straight into whipped cream. But that makes for a much heavier, much sweeter mousse. Just another few ingredients are all it takes to make this super light and fluffy, not-too-sweet mousse.
This white chocolate mousse simply must be served chilled, or it tends to wilt. That's really not a Very Big Problem. If you're serving it on a warm day, just keep it in the refrigerator until right before you're ready to serve it.
When you make this recipe with store bought white chocolate, you'll need to be extra careful not to try to heat the chocolate too quickly or it will seize and possibly separate. If that does happen, don't panic! Add the butter and the rehydrated dry milk, and just keep stirring. It should come together smoothly.
Ingredients and Substitutions
I like to provide you with as much information as possible about the ingredients in my recipes, and possible substitutions for them. Please keep in mind that, unless I specifically indicate that I've tried the substitution myself, you're working off my best-educated guess.
Dairy: If you use my recipe for vegan white chocolate, you're half of the way (a quarter?) to making this recipe dairy free. If lactose is your issue, you should probably be fine with the heavy whipping cream. If not, try using coconut cream in place of heavy whipping cream. The whipped cream won't be quite as stable, though, and will taste a bit, well, coconutty.
In place of the nonfat dry milk, use coconut milk powder, which is much more widely available than it used to be. In place of butter, try butter-flavored Spectrum nonhydrogenated vegetable shortening. Boy, that's a lot of dairy to replace.
Eggs: Haha just kidding; this recipe is already egg-free.
Sugar: This recipe simply needs confectioners' sugar in both the white chocolate (unless you can find sugar-free white chocolate, in which case bless your heart). The only substitute that I know for confectioners' sugar is Swerve brand powdered sugar replacement. Try that!
White Chocolate Mousse
2 cups (16 fluid ounces) heavy whipping cream, chilled
1/2 cup (58 g) confectioners’ sugar
1/4 cup (24 g) nonfat dry milk
1/3 cup (2 2/3 fluid ounces) hot water
10 ounces white chocolate, chopped (plus more shavings for serving)
4 tablespoons (56 g) unsalted butter, chopped
1 teaspoon pure vanilla extract
Berries, for serving
In the bowl of a stand mixer fitted with the whisk attachment, or in a large bowl with a hand mixer, whip the heavy whipping cream on medium-high speed until soft peaks form. Add the confectioners’ sugar and beat until stiff, glossy peaks form. Place the bowl of whipped cream in the refrigerator to chill.
- In a small bowl, whisk the dry milk into the hot water until it dissolves completely. Set it aside. Place the chopped white chocolate in a small, heat-safe bowl, and place it over a bowl of simmering water to create a double boiler, stirring occasionally until the chocolate is melted and smooth. Add the butter and vanilla, and mix until once again melted and smooth. Remove the bowl from the heat. Whisking constantly, add the milk powder and water mixture. Whisk until smooth. Set the mixture aside to cool, whisking occasionally until the bowl that the chocolate mixture is in is no longer hot to the touch, about 5 minutes.
Remove the large bowl of whipped cream from the refrigerator, and pour the slightly cooled chocolate mixture into the bowl. Carefully mix and fold the ingredients together, taking care not to deflate the whipped cream more than necessary. Divide the mixture among serving jars or bowls. Cover and refrigerate until set, about 2 hours. Serve chilled, with white chocolate shavings and berries.
