Ingredients
  

  • 10 ounces white chocolate finely chopped
  • 1 and 1/2 cups heavy whipping cream cold
  • 1/2 cup whole milk

Instructions
 

  • Melt the white chocolate gently. Place the finely chopped white chocolate in a heatproof bowl set over a pot of barely simmering water. Make sure the bottom of the bowl does not touch the water. Stir frequently with a spatula until completely smooth. Remove from heat and let cool for about 5 minutes. The chocolate should feel warm but not hot to the touch.
  • Whip the cold heavy cream. In a separate large bowl, beat the cold heavy whipping cream with a hand mixer or stand mixer on medium-high speed until soft peaks form. Soft peaks mean the cream holds its shape briefly but still droops when you lift the beaters. Do not overwhip to stiff peaks, or the mousse will become grainy.
  • Fold the whipped cream into the chocolate. Add about half of the whipped cream to the slightly cooled white chocolate. Use a large rubber spatula to fold gently, cutting through the center and lifting from the bottom, until no streaks of chocolate remain. Then add the remaining whipped cream and fold again just until fully incorporated. Be patient and gentle. Overmixing will knock out the air and make the mousse dense.
  • Add the whole milk. Pour the whole milk into the mousse mixture and stir gently with the spatula until well combined. The milk loosens the mousse slightly, making it easier to spoon into molds and giving the final texture a softer, creamier mouthfeel.
  • Fill the molds. Spoon the mousse into dome-shaped silicone molds, filling each cavity to the top. Tap the mold gently on the counter a few times to release any large air bubbles. If you are using ramekins or a serving dish, simply spoon the mousse in and smooth the top with an offset spatula.
  • Refrigerate until set. Place the filled molds in the refrigerator for at least 240 minutes, or 4 hours. For best results, chill overnight. The mousse needs this time to firm up enough to hold its dome shape when unmolded.
  • Unmold and serve. To remove the domes, gently press on the bottom of each silicone cavity or run a thin knife around the edge of a ramekin. Invert onto a serving plate. If the domes resist, dip the mold briefly in warm water for 2–3 seconds, then try again. Serve immediately.

Notes

Optional substitutions and tips: Use high-quality white chocolate with at least 30% cocoa butter for the best flavor and texture. Cheap white chocolate chips often contain too much wax and will not melt smoothly. For a dairy-free version, swap the heavy cream for full-fat coconut cream and the whole milk for unsweetened almond or oat milk. The mousse will still set but may have a subtle coconut flavor. If you do not have dome molds, small ramekins, silicone cupcake liners, or even a single serving bowl work beautifully. Make sure the heavy cream is very cold before whipping. Warm cream will not reach soft peaks and can deflate the mousse.
