Here is my go-to white chocolate Baileys mousse recipe, with a smooth, creamy texture that combines rich white chocolate, a generous splash of Irish cream, and light-as-air whipped cream.
This dessert has become my friends’ favorite choice for dinner parties and special occasions. I often make an extra batch to keep in the fridge because everyone always asks for seconds. Nothing beats having a little fancy dessert waiting for you after a long day, right?

Why You’ll Love This Baileys Mousse
- Quick dessert – This elegant mousse comes together in less than 40 minutes, making it perfect for last-minute dinner parties or when you need a quick sweet fix.
- Simple ingredients – With just 8 basic ingredients, most of which you might already have in your pantry, this recipe is surprisingly straightforward to make.
- Make-ahead friendly – You can prepare this mousse several hours or even a day before serving, which makes party planning so much easier.
- Adult dessert option – The Bailey’s Irish Cream adds a sophisticated twist to classic white chocolate mousse, making it perfect for grown-up gatherings or date nights.
What Kind of White Chocolate Should I Use?
For mousse, it’s really important to use real white chocolate that contains cocoa butter, not the white baking chips or candy melts that are made with palm oil. Check the ingredient list – the first few items should include cocoa butter and milk solids. Good quality white chocolate bars from brands like Ghirardelli, Lindt, or Callebaut will melt smoothly and give your mousse the right texture and flavor. When you’re melting the white chocolate, take it slow and steady – white chocolate can be a bit finicky and will seize up if it gets too hot. A double boiler or short bursts in the microwave at 50% power work best for getting that perfectly smooth melt you need for mousse.

Options for Substitutions
Need to make some swaps for this mousse recipe? Here’s what you can try:
- Gelatin: If you’re vegetarian, you can use agar agar powder instead of gelatin – use the same amount, but be sure to boil it with a bit of water first to activate it properly.
- Bailey’s Irish Cream: No Bailey’s? Try another cream liqueur like Kahlua, RumChata, or make your own by mixing 2 tablespoons heavy cream with 1/2 teaspoon instant coffee and 1/2 teaspoon vanilla extract.
- White chocolate: This is a key ingredient that shouldn’t be substituted as it’s crucial for the mousse’s texture and flavor. Just make sure to use real white chocolate, not candy melts or chips.
- Whipping cream: Heavy cream works perfectly here too. Just don’t try to use half-and-half or milk – the mousse won’t set properly.
- Egg yolks: For food safety reasons, use pasteurized eggs if you’re concerned about raw eggs. There’s no good substitute for egg yolks in this recipe as they’re essential for the mousse’s structure.
Watch Out for These Mistakes While Making
The trickiest part of making white chocolate mousse is properly tempering the egg yolks – if you add them directly to the hot mixture, you’ll end up with scrambled eggs instead of a smooth mousse. To prevent this, slowly stream a small amount of the warm cream mixture into the egg yolks while whisking constantly, then pour this mixture back into the main pot. Another common mistake is not letting the gelatin bloom properly – make sure to let it sit in the hot water for a full 5 minutes until it’s completely dissolved and slightly translucent. When melting the white chocolate, keep the heat low and stir frequently to prevent it from seizing or becoming grainy – if it does seize, try whisking in a few drops of warm cream to smooth it out. Finally, when folding in the whipped cream, be gentle but thorough – overmixing will deflate your mousse, while undermixing will leave you with white chocolate streaks.

What to Serve With Baileys Mousse?
This creamy, boozy dessert pairs perfectly with a hot cup of coffee or espresso to balance out its sweetness. Since the mousse is already rich and decadent, I like to serve it with some fresh berries on top – raspberries or strawberries work especially well and add a nice pop of color. For an extra special touch, you could drizzle some dark chocolate sauce over the top, which creates a nice contrast with the white chocolate in the mousse. If you’re serving this at a party, set out some crisp butter cookies on the side for a bit of crunch!
Storage Instructions
Chill: This Bailey’s mousse needs at least 4 hours in the fridge to set properly, but it’s best when chilled overnight. Cover each serving glass or container tightly with plastic wrap to prevent the mousse from absorbing any fridge odors or forming a skin on top.
Keep: You can keep your mousse in the refrigerator for up to 3 days. The texture is usually best within the first 48 hours – after that, it might start to lose some of its fluffiness, but it’ll still taste great!
Make Ahead: This dessert is perfect for preparing in advance for parties or special occasions. You can make it up to 2 days before serving. Just remember to keep it covered in the fridge and add any toppings like chocolate shavings or whipped cream right before serving.

Ingredients
For the mousse:
- 1/8 tsp salt
- 2 large egg yolks
- 1 cup whipping cream (cold, for best whipping results)
- 4 oz melted white chocolate (cooled slightly)
- 3 tbsp sugar
For the gelatin mixture:
- 2 tbsp Baileys Irish Cream (adds a distinct, rich flavor)
- 1 tsp plain gelatin
- 1 tbsp hot water (to dissolve the gelatin completely)
Step 1: Prepare the Gelatin Mixture
Start by mixing 1 teaspoon of unflavored gelatin with 1 tablespoon of hot water in a small bowl.
Allow this mixture to stand until the gelatin has softened.
Step 2: Dissolve Gelatin in Bailey’s Irish Cream
In a microwave-safe bowl, heat 2 tablespoons of Bailey’s Irish Cream liqueur until hot, about 30-45 seconds.
Stir the hot liqueur into the softened gelatin until the gelatin is fully dissolved.
Step 3: Whip the Cream
Using the bowl of a stand mixer, whip 1 cup of heavy cream until firm peaks form.
Once whipped, place the cream in the refrigerator to keep it cool while you complete the other preparations.
Step 4: Prepare the Egg Yolk Mixture
In the stand mixer, whip together 2 large egg yolks, 3 tablespoons of sugar, and 1/8 teaspoon of salt.
Whip on high speed until the mixture becomes pale and thickened, which should take about 4-5 minutes.
Step 5: Melt the White Chocolate
During this time, melt 4 ounces of white chocolate.
You can do this in the microwave or using a double boiler until the chocolate is fully melted and smooth.
Be sure to stir frequently to avoid any burning.
Step 6: Combine All Elements
Once the egg yolk mixture is pale and thickened, beat in the gelatin mixture and the melted white chocolate.
Scrape down the sides of the bowl as needed to ensure everything is fully incorporated.
Step 7: Fold in Whipped Cream
Take the cooled whipped cream from the fridge and gently fold it into the egg yolk mixture by hand, using a rubber spatula.
Fold in the cream in two additions, ensuring you don’t deflate the airy texture of the mixture.
Step 8: Serve the Mousse
Transfer the finished mousse into serving bowls.
Refrigerate for a few hours to set fully if desired, or serve immediately for a delightfully creamy treat.
Enjoy your decadent Bailey’s Irish Cream and white chocolate mousse!
