Did you know that vanilla is a bean pod produced by an orchid? If you read about how vanilla beans are produced you can understand why they are the second most expensive spice in the world (after saffron).

Despite the fact that folks use the phrase “plain vanilla” to describe something that is basic or uninteresting, I say that real vanilla flavor is anything but boring.

This Vanilla Mousse recipe is a great way to highlight and appreciate the complex floral flavor of the vanilla bean.

To truly appreciate the vanilla flavor, serve this dessert au naturale. But it’s also lovely topped with fresh fruit, chocolate sauce, chocolate shavings or fruit puree.

Vanilla mousse also makes a great cake filling, especially between layers of light and airy Vanilla Genoise or Vanilla Chiffon Cake.

For you chocoholics I recommend this classic Chocolate Mousse recipe and for fruit lovers I think you’d like Fresh Strawberry Mousse.

  • 8 oz whole milk (1 cup)
  • 1 vanilla bean (split)
  • 4 oz granulated sugar (½ cup, divided)
  • ½ oz corn starch (2 tablespoons)
  • 4 large egg yolks
  • 8 oz heavy cream (1 cup)
  • 2 tablespoons dark rum (or other liquor or water))
  • 1 ½ teaspoons plain gelatin powder
  • 2 large egg whites


  • Place 8 oz whole milk in a pot over medium high heat. Scrape the seeds from 1 vanilla bean and add them to the milk along with the pod. Heat until the milk is scalding hot, but not boiling.
  • Remove 2 tablespoons of the granulated sugar and set it aside.
  • While the milk heats up, whisk together the rest of the sugar with ½ oz corn starch and4 large egg yolks. Whisk the hot milk into the egg yolks, then return the mix to the heat. Cook the custard over low heat, stirring constantly, until the mixture just begins to boil and thickens. Remove from the heat and strain into a clean bowl. Discard the vanilla pod or rinse it and set in a bin of sugar to make vanilla sugar.
  • Refrigerate the custard for at least 2 hours (must be completely cooled) before continuing with the recipe. To speed up cooling, you can set the bowl of custard over a bowl of ice water and stir until cooled.
  • Whip8 oz heavy cream to soft peak and fold it into the chilled custard base. Return the bowl to the refrigerator while you prepare the other ingredients.
  • Place 2 tablespoons dark rum (or cool water) into a microwave safe bowl. Sprinkle 1 ½ teaspoons plain gelatin powder in an even layer over the rum and set it aside to bloom.
  • Combine 2 large egg whites with the reserved 2 tablespoons of sugar in a heatproof mixing bowl. Set the bowl over the pan of almost simmering water (don't allow the bottom of the bowl to touch the water) and heat to 160 °F, stirring constantly. Remove the whites from the heat and whip until they are at full peak and completely cooled.
  • Heat the bloomed gelatin in the microwave in 10 second increments until it's hot to the touch. Working quickly, add a ½ cup of the mousse to the warmed gelatin. Whisk to combine. Pour the gelatin mixture back into the mousse. Immediately whisk until the mousse is smooth and the gelatin is evenly incorporated. Immediately fold the whites into the mousse.
  • Pipe or spoon the mousse into serving dishes while it's is still soft. Refrigerate until set. Serve with fresh berries, fruit sauce or chocolate shavings.

    1. I could say 100% without testing, but my instinct would be to add hazelnut butter to the hot custard. The final mousse may be a bit heavier, but I think that should work.

    1. Full peak means when you lift the whisk and hold it up the egg whites peak and hold their shape without slumping over. It is possible to go too far after full peak and over whisk the whites. At some point if the whites start spinning in the bowl they have release some of the water and the structure is weakened. As soon as the whites hold their shape they are ready.

  1. Wow! This recipe is so delicious. It was a ton of work but the mousse set properly and I super appreciated that the egg whites were not raw but cooked to 160*. Will I make again? Maybe – it is a lot of work. Will I want others to make it for me? Yes. I paired with some strawberries that complimented it perfectly.

    1. Glad you liked it. It is perhaps a “special occasion” recipe. But, once you go through the process, it is quicker the next time.
