Finding the perfect dessert for special occasions can feel like a real puzzle. We all want something that looks fancy enough to impress our guests, but nobody wants to spend hours in the kitchen wrestling with complicated techniques or hunting down hard-to-find ingredients.
That’s why this white chocolate orange mousse has become my go-to dessert recipe: it’s surprisingly easy to make ahead of time, relies on simple ingredients you can find at any grocery store, and combines two flavors that were just meant to be together.
Why You’ll Love This White Chocolate Mousse
- Make-ahead friendly – You can prepare this mousse up to 24 hours in advance, making it perfect for dinner parties or special occasions when you want to minimize last-minute prep.
- Luxurious taste – The combination of smooth white chocolate and fresh orange creates a sophisticated dessert that tastes like it came from a fancy restaurant.
- Light and airy texture – The whipped egg whites and cream give this mousse an incredibly smooth, cloud-like consistency that melts in your mouth.
- Impressive presentation – With its elegant white color and orange zest garnish, this dessert looks beautiful on the table without requiring any fancy decorating skills.
What Kind of White Chocolate Should I Use?
For mousse, you’ll want to stick with real white chocolate that lists cocoa butter as one of its main ingredients – skip those “white baking chips” or compounds that use other fats instead. Good quality white chocolate like Ghirardelli, Lindt, or Callebaut will melt more smoothly and give your mousse a better texture and taste. When you’re shopping, check the label to make sure you’re getting the real deal – if it doesn’t contain cocoa butter, it might leave your mousse grainy or too sweet. Just remember to chop your white chocolate into small, even pieces before melting to prevent it from seizing, and always melt it gently using low heat or a double boiler setup.
Options for Substitutions
While some ingredients are key to getting this mousse just right, there are several substitutions you can try:
- White chocolate: This is a must-have ingredient that shouldn’t be substituted as it’s the base of the mousse. Make sure to use real white chocolate (with cocoa butter) and not candy melts.
- Gelatin powder: For vegetarian options, you can use agar agar powder instead – use the same amount but be sure to boil it briefly to activate. Keep in mind the texture might be slightly different.
- Orange liqueur: Don’t want to use alcohol? Simply use orange juice instead. You can also try orange extract (use just 1/2 teaspoon) mixed with water to make up the full amount.
- Crème Anglaise: If you can’t find or make Crème Anglaise, you can use vanilla custard sauce from the store. Just warm it slightly before using.
- Egg whites: For food safety or dietary concerns, you can use pasteurized egg whites from a carton – measure about 120ml as a replacement.
- Orange rind: If fresh orange isn’t available, you can use 1-2 teaspoons of dried orange zest, or even a mix of lemon and mandarin zest for a similar citrus note.
Watch Out for These Mistakes While Making
The biggest challenge when making white chocolate mousse is temperature control – if your melted chocolate is too hot when combining with other ingredients, it can seize up or become grainy, so always let it cool until just warm to the touch.
When working with gelatin, a common mistake is not letting it bloom properly in cold water first – give it a full 5 minutes to soften before dissolving in hot water, and make sure it’s completely dissolved before adding to your mixture to avoid unpleasant lumps.
Egg whites need special attention too – make sure your bowl is completely clean and free from any traces of fat, as even a tiny bit of egg yolk will prevent proper whipping, and fold them in gently using a figure-eight motion to maintain the air bubbles that give your mousse its light texture.
For the perfect orange flavor balance, add the orange zest gradually and taste as you go – it’s easier to add more than to fix an overpowering citrus taste.
What to Serve With White Chocolate Orange Mousse?
This light and creamy dessert pairs wonderfully with a few simple accompaniments that won’t overshadow its delicate orange and white chocolate flavors. A handful of fresh berries – especially raspberries or strawberries – adds a nice pop of color and brings a bit of tartness that balances the sweetness of the mousse. I like to serve it with thin, crispy butter cookies or shortbread on the side, which give a nice contrasting crunch. For drinks, try serving it with a small glass of dessert wine like Moscato d’Asti or even a cup of Earl Grey tea, whose bergamot notes really complement the orange in the mousse.
Storage Instructions
Chill: Once you’ve prepared your white chocolate orange mousse, cover each serving with plastic wrap pressed directly onto the surface to prevent a skin from forming. Pop it in the fridge for at least 4 hours to set properly, though overnight is even better for the flavors to develop.
Keep: This mousse will stay good in the fridge for up to 3 days. Just remember to keep it covered – those citrus and chocolate flavors are wonderful, but they can also pick up other fridge smells if left uncovered!
Serve: Take the mousse out of the fridge about 10-15 minutes before serving to let it soften slightly – this brings out the orange and white chocolate flavors beautifully. Add your whipped cream topping just before serving for the best presentation.

Ingredients
- 180 grams white chocolate
- 3 tablespoons hot water
- 1½ teaspoons gelatin powder
- 4 egg whites or from 3 larger eggs
- 30 ml orange liqueur or orange juice
- 200 ml store-bought or homemade crème anglaise (if using your recipe, omit orange and cardamom infusion, and make half)
- Grated rind of 1 orange
- Whipped cream
Step 1: Melt the Chocolate
Pour about 5 cm of water into a medium-sized pot and bring it to a simmer over medium heat.
Once simmering, switch off the heat and place a heatproof bowl on top of the pot, ensuring it fits snugly but does not touch the water.
Break the chocolate into pieces and place them in the bowl.
Allow the chocolate to melt slowly, stirring occasionally, until fully melted and smooth.
Step 2: Prepare the Gelatine Mixture
In a separate small bowl, mix together some boiling water and gelatine until the gelatine is fully dissolved.
Set this mixture aside to cool slightly while you proceed to the next steps.
Step 3: Whisk the Egg Whites
Using an electric beater, whisk the egg whites in a separate bowl until they form soft peaks.
This means the egg whites should hold their shape but still have a smooth, glossy appearance.
Step 4: Combine Gelatine and Chocolate
Return to the bowl on top of the pot.
Stir in the gelatine mixture and your choice of liqueur into the melted chocolate.
Whisk the mixture until it is smooth and integrated, keeping the bowl over the warm pot to maintain the mixture’s temperature.
Step 5: Add Crème Anglaise and Orange Zest
Remove the bowl from the pot and whisk in the Crème Anglaise and orange zest until the mixture is smooth and well combined.
Ensure the mixture remains fluid and does not seize.
Step 6: Fold in Egg Whites and Chill
Using a large metal spoon, gently fold the beaten egg whites into the chocolate mixture until fully combined, being careful not to deflate the egg whites.
Pour the mousse mixture into 6 serving glasses or ramekins.
Chill in the refrigerator for at least 2 hours until set.
Step 7: Top and Serve
Just before serving, top each mousse with a dollop of whipped cream.
Enjoy your rich and creamy chocolate dessert!
